Imagine that you are working away in the shop. As usual around lapidary work, there’s a little water on the floor. As usual, you pay little attention. You reach over to turn the switch on your equipment. ZAP! Would you rather 1. Your family learned CPR so that they might rescue you when you are electrocuted? OR 2. You felt a short tingle, the electricity turned off, and you went to work to find and repair your machine’s electrical short? One doesn’t have to be a genius to know you’d prefer number 2. But, have you prepared so that number 2 is assured. If not, read on. There is a device called a ground fault interrupter (GFI). If answer number 2. appeals to you, you should learn about them and get some installed. What does the GFI do for you? GFIs detect the flow of current when something (perhaps you) in the circuit is grounded and, in a millisecond, turn off the current. If you are in the grounding circuit, it happens so fast that it will be over before you realized that you were in the circuit. Your life is spared. No sparks fly. No fire starts. Just, suddenly, the electricity is off. GFI’s come in a couple of forms. One is as a unit to fit into your master electrical panel board. It will protect all the electrical equipment plugged in that circuit. The other is as a replacement in your wall plug-in box. It protects everything plugged into that one box. Neither is expensive ($12 to $25). But, most of us don’t want to (and shouldn’t) fool around with the back of our master panel board, So, it is best to have an electrician install GFI’s there. You can install one in the wall box yourself IF you know what you are doing. If you don’t, call an electrician for that, too. The saddest feeling known is to say to yourself “If I had only done that first." Get your GFI’s and install them now! Side thought - It is an excellent idea to put these on any circuit near a water faucet - especially around the bathroom, the kitchen, and the laundry. by Mel Albright - AFMS Safety Chairman Angle of repose REPOSING EASILY Whenever we rock hounds go on a field trip, we are likely to be around a creek bed, a road cut, a quarry, a steep bank, or a spoils pile. If so, we should all remember that there is something called the angle of repose. No, I'm not talking about how flat you should be when you lie down to rest. The angle of repose is a civil engineering term. It is a fact that a pile of anything - sand, rocks, marbles, hay, or whatever - has the property that the slope of the side of the pile determines whether the pile slides down or not. If the slope is over the angle of repose, it WILL slide - sooner or later. If it less than the angle of repose, it will sit there forever without sliding. The angle depends on the materials in the pile and on their sizes, so there is no general rule as to what angle is safe. Therefore, most road cuts and fills are slightly less steep than the angle of repose. If you stand below or try to climb a slope that is too steep for the material it is made of, there is a very good chance that the top will come down on you. It gets more complicated. Consider what happens when you step into the side of a slope. Your foot forms a hollow. This means the material just above and just below your footprint is at too steep an angle. So, it slides down. As it goes, it continuously forms a slope that is too steep, so the material slides and slides and forms a major slump. If you are trying to ride it or if you are below it, that is not good. When you dig or extract a sample from a pile or a cliff or a quarry wall, the same thing happens. If you dig a tunnel, you have definitely formed a highly unstable slope and the slightest jar may bring it all down on you. That's why mines have shoring. Several children are killed each year because of this. I'm sure you have heard of it. So, when hunting rocks, test the slope you're on or below for stability before getting into a position where you might get hurt or buried. And, always keep an eye on any rock hound that is above you. They might start something that hurts you! by Mel Albright - AFMS Safety Chairman Sun protection DANGER - SUNSHINE One of the fastest increasing diseases today is skin cancer. It is caused by too mush sunshine. It does not appear right after you get too much sun, though. It will appear 10, 20, 30, or more years later. So, the only sure protection is to start now to develop good habits to avoid sun damage to your skin. Then, keep on being careful. The basic cause of damage from the sun is through ultraviolet radiation. Recent research has said that one serious sunburn as a child can lead to cancer. Recent research reports that sunscreen does not protect against skin melanomas - the deadliest cancer. In my area, our TV weathermen report the UV exposure factor. They include the safe exposure time. In summer, it typically is something like 8 minutes for fair skin people, 14 for medium skin people, and 22 for dark skin people. The Skin Cancer Foundation recommends the following as ways to prevent and control skin damage from the sun. Stay out of the sun during the most dangerous times - 10 AM to 2 PM (11 AM to 3 PM daylight time). Wear a hat, a long sleeve shirt, and long pants (tight-knit cloth) when in the sun. Apply sunscreen before going out and re-apply every 2 hours or after swimming while outside. Use at least a 15 SPF sunscreen on all exposed skin (the 15 means it takes 15 times as long to reach the same sun exposure as with no sunscreen). The higher the altitude, the more UV comes to you and the more sunscreen is needed. Cloudy days do not protect you - UV comes right through clouds. If you work outside, use sunscreen daily. A tan does NOT protect you. Some medicines, drugs, cosmetics and birth control pills make you more sensitive to sun damage. If you develop and allergy to one sunscreen, change to another one. Watch out for reflective surfaces - sand, snow, water (The Great Salt Plains). Staying in the shade doesn’t help around these. Stay out of tanning parlors. Keep infants out of the sun. Start using sunscreen on children when they are 6 months old. Teach your children sun protection early and insist they follow the rules.

What’s your reaction when someone says there’s going to be a safety talk? If you’re like most people, you immediately wish you were somewhere else. Is it because the people who talk about safety are boring? Or, do you consider yourself infallible and immortal? Yes, many speakers are and no you aren’t either. When we get bored at the sound of the word "safety", we’re not really thinking danger is a part of the things we do. However, we are engaged in a hobby in which there are a great number of ways to hurt yourself or be hurt by others. So, we really should think about what we are doing and how we are doing it. We use poisonous materials, have flammable materials, use acid and caustic materials, use fire, generate dangerous fumes, drive in convoys, get out in the sun a lot, are often around unstable cliffs, ditches, and the like, use tools which often release flying material, use electrical equipment around water, use rotary tools, and more. Do you know how to protect yourself and your friends in every one of these cases. Or, are you like many of us? - just go ahead and never think about something going wrong? Do you own protective equipment - like canvas and rubber gloves, eye protection, safety shoes, safety hats. If you own them, do you use them? Face it, most of us don’t. Can you treat insect and snake bites? May I suggest something new? How about a "Safety Minute" at each club meeting. Either have a safety chairman or ask someone new each meeting to simply mention some one thing that people in the club do that should require safety considerations. No one has time to get bored. Everyone is reminded that there are ways to get hurt in following this hobby. An extra free benefit of this idea is that people will become more safety conscious even doing things that are never mentioned in the meeting. Hey, give it a try! by Mel Albright - AFMS Safety Chairman Skin cancer DO YOU SEE SPOTS? The next time you take a bath, stop afterwards and look over your skin all over your body. Do you see any spots? See any rough patches of skin? See any small "bumps" of white dead skin? Any moles that are changing or growing? Any thing else that looks unusual? If you do, it is time to see a Dermatologist. Maybe QUICK! Sun damage to the skin is one of the major health problems today. But, it is not caused by what you have done lately. It depends on you sun exposure 10, 20, 30, or even 40 years ago. By far, the most serious problem you might see is melanoma cancer. This cancer spreads rapidly and is deadly. The four things that might indicate melanoma are: A varied color growth that is asymmetric, has irregular edges is something to worry about. If it is larger than 6 mm in diameter, it is really dangerous. This includes long time moles that change size, color, or shape. Run! do not walk, to the doctor if you see something that might be this. Next in importance are basal cell carcinoma and squamous cell carcinoma. Although not as deadly as melanoma, these can be serious if not treated. Any of these 5 things might indicate that these are present. 1. An open sore that bleeds, crusts, or oozes for more than 3 weeks. 2. A reddish patch. It may sometimes be crusty. It may itch or hurt. 3. A smooth growth with a rolled border with an indentation in the middle. 4. A shinny bump or nodule which is pearly or translucent. They are often pink, red, or white. Less common, they may be tan, black, or brown. They MAY BE CONFUSED with a mole. 5. A scarlike area which is white, yellow or waxy. It will be shinny and the surrounding skin is taut. Also important are three pre-cancerous conditions. These may lead to cancer if they are untreated. Solar or actinic keratoses occur as rough, dry, pink to tan patches on sunexposed skin. These are caused by the ultraviolet in the sun and. Leukoplakia is a smooth, white patch which affects the mucous membranes, primarily the lips and inside the mount. Radiodermatitus appears as a mottled area with a decrease of skin pigment. We’ll discuss how to limit skin damage from the sun in another article.

You can’t quite tell if it's any good. You want to see what’s inside. So, you take your rock hammer or another rock and hit it to chip off a piece. ZING, a chip hits your eye. You are now one-eyed. That great specimen you want is partially buried in the matrix right there!. All you have to do is get it loose without breaking it. So, you grab a chisel and a hammer and start chipping. ZING, a chip hits your eye. You are now one-eyed. You need to get that rock out of the ground. All it needs is a little prying. You grab a crowbar, point the end at the crack and bang it down to force it into the ground. ZING, a chip hits your eye. You are now one-eyed. You want some rocks for tumbling. All you have are too big. So, you grab a big one, set it down on the ground, take a hammer and bang away. ZING, a chip hits your eye. You are now one-eyed. Your piece of slab is too big. It’s real time consuming to trim it with your saw. So, you grab a pair of pliers, grab a corner, and pry to break it off. ZING, a chip hits your eye. You are now one-eyed. OR, you score the slab with a glass cutter, line the score over a bench edge, and start tapping to break it. ZING, a chip hits your eye. You are now one-eyed. You’re cleaning a fossil. As you chip away to get matrix off, you lean closer and closer to see that you get it exactly right. Suddenly your hammer slips and bounces. ZING, the hammer hits your eye. You are now one-eyed. You’re gluing with epoxy. You get a little hardener on your hand. You wipe the sweat off your forehead. You get a little hardener in your eye. ZING, you are now one-eyed. Wild? Exaggerated? Not really. It happens all too often. Plastic safety glasses at WalMart - about $1. Plastic face shield at WalMart - about $5. Worth it? by Mel Albright - AFMS Safety Chairman Sun stroke/sun exhaustion SUN SAFETY Do you ever hunt rocks on a warm to hot day? Garden? Hike? Or something else active? Then, in much of the United States, you’d best learn to recognize the symptoms of thing going wrong when we get too hot. HEAT CRAMPS are the less serious, but still dangerous result of too much heat. These are spasms of the muscles brought on by exertion in hot weather. Many times, the calves are the first muscles affected. What causes cramps? Intense sweating followed by drinking of salt free water. They are more likely to occur if you’re out of shape, in poor health, tired, or have been drinking alcohol. BUT, they can occur to anyone! To avoid cramps, take it easy in hot weather, eat salty foods or take salt tablets, or drink athletic drinks that have salt in them. If cramps occur, stop, get in a cool place and rest, stretch and message the cramped muscle. Drink something salty. HEAT EXHAUSTION occurs when you run out of body salt and/or water. Symptoms are fatigue, lightheadedness, thirst, maybe cramps, spasms, nausea and/or vomiting. Mental ability will be normal. Low grade fever (99 to 102F), a rapid pulse, and dehydration are often present. In HEAT STROKE, the most serious effect, the individual will have a high fever (104 to 106F). There will be mental confusion, unusual behavior, convulsions, or coma. The blood pressure may be dangerously low from shock. IMMEDIATE CARE for heat exhaustion or heat stroke includes moving the individual to air-conditioning, lying on their back, with a fan if available. Remove or loosen tight clothing, place cool compresses on forehead, neck, and under arms. You may sprinkle water on them, but do not put them into a tub or swimming pool. If they vomit, give them nothing by mouth. Otherwise cold, salt-containing liquids will help. Use 4 teaspoon salt in 1 quart water and give them 4 oz. every 15 minutes. If symptoms persist, or if they are unconscious, transport immediately to a hospital. Remember, some people tolerate heat better than others. Even though you feel fine, if any of the above symptoms starts, act immediately. Continuing on and insisting "I’m O.K." or "I’ll be O.K. in a minute."is NOT the way to go. It can only make things worse. Reference: COMPUSERVE FIRST AID SECTION Convoy FOLLOW ME!!! by Mel Albright, AFMS Safety Chair For many rockhound clubs, the field trip season is upon us. For others, it is fast approaching. So, now is an appropriate time to think about such trips. In the classical fashion, everyone meets at 7:30 AM at McDonalds or some such arrangement. Then, the leader says "Let’s go!" - "Everyone follow me.", jumps into his vehicle and goes driving off down the road. Everyone else falls in behind and each driver careful tries to memorize the car ahead of him so he won’t get lost. And - AWAY THEY GO! What are the problems with this? First, let’s consider the dynamics of the "follow the leader" approach. The lead driver takes off, and, usually drives at the speed limit or a little slower. The next car can’t exactly match his speed, so they get close and slow down, then get farther away, and speed up. The next car’s speed is even more erratic. By the time you get to "tail-end Charlie", he’s going anywhere from 20 miles under the speed limit to 20 over just trying not to be left. Then, throw in a stop sign or traffic light. Some cars go through, there’s a pause for traffic, then a few more go, then there’s another pause, and so on. After a few cycles, the cars have to speed like crazy to re-find those that went ahead. During all this, the driver is concentrating on the convoy - not on traffic. So, the chances of an accident go way up. Sometimes, less daring drivers refuse to speed and they and many behind are lost and miss the field trip. SOOOO! For safety, several things need to be done. First, before starting, every driver should get detailed directions or a map of where they are going. Then no one is afraid of losing out. This way, no driver is afraid of being left behind, so they can concentrate on traffic and road conditions. Second, the leader should drive 5-10 miles under the speed limit at as nearly a constant speed as possible to minimize yo-yoing. Third, the convoy should pull to the side of the road and wait for everyone to catch up any time there’s a turn, a stop sign, a town to go through, or a traffic light. Finally, it would really help if the leader is in radio (CB) contact with a buddy who has agrees to be "tail-end Charlie". Then, if there’s a flat or any other problem, the leader can stop and wait for things to be straightened out. HONK! HONK! HEY, WE GOT US A CONVOY HERE! Bugs and varments BUGS AND VARMINTS by Mel Albright (AFMS Safety Chair) Whenever we go rock hunting, we should remember that we’re going into someone else’s world. Who’s? Well, we really don’t know. It might be some snake, some bug, some plant, or, even, something really big - like a bear. So, how do we prepare to be friendly - or at least not to make something mad? Often, the best thing to do is simply not to go there. If there’s poison ivy or poison oak or poison sumac around, go somewhere else. By the way, can you recognize all or any of these that thrive in your neck of the woods? If not, best get someone to show you. Believe me, it’s better than finding out the hard way. As a kid, I spent 2 weeks of my life in bed from poison ivy. What about snakes? First, remember most are not poison. Second, remember that some are. Third, find out the difference. In the United States, they state that there are only a few - rattle snakes, cottonmouth snakes, coral snakes and copperheads. Believe it or not, the snake would rather not bite you. If they don’t feel threatened, they’ll leave you alone. So, when in snake country, there are a few rules: Do not walk fast; Look before putting your foot down; Don’t jump or step over stuff- logs, rocks, etc.; Don’t reach into dark places before you look to be sure no one’s there; Don’t put your stuff on the ground where it might provide cover for a snake. And remember, a rattle snake does NOT always rattle first! Then there’s bugs and spiders who can be unfriendly - scorpions, black widows, fiddle-backs, and the like. Again, a few simple rules will cover you - Don’t reach into a place before looking into it. Don’t put one hand down to support yourself while doing something else without checking out where it’s going. When you reach under something, you are reaching into the bug’s domain . Turn it over instead. Shake out any shoes, clothing, bed rolls, or whatever before putting yourself into them. Never say that some place is too tight for a bug. You’d be amazed at what a small crack a scorpion can sneak through (and loves to do so). I got a fiddleback bite one time by sitting on my garden tractor. The spider was under the seat! Now I look first. Then there are the nuisance bugs - ticks, chiggers, no-see-ums, gnats, skeeters, and the like. Here, the best way is to be prepared. Use bug repellent BEFORE venturing out. Dust your ankles with flowers of sulfur. Don’t wear floral or sweet scents. Wear shirts with sleeves and long pants. Bees, wasps, hornets, and bumble bees are usually highly visible. Watch for them! Remember, that hole in the ground might be the entrance to a bumble bee nest! Also, remember that many soft drinks are attractive to them and they can and do land on your pop can - even while you’re holding it. Finally, consider the bigger stuff - bears, skunks, and their neighbors. Be noisy, talk and rattle, and look ahead and they’ll be no problem. One exception - if you see ANY wild animal that doesn’t seem afraid or, even, approaches you, try your very best to avoid them. THEY MIGHT BE RABID! If you see a nocturnal animal wandering around in the daylight, there again is a good chance that it is rabid. In my area, that is especially true for skunks, possums, fox, and raccoons. Check with the agricultural or wildlife people in your area if you are not sure what wild animals might be rabid. Laboratory/shop THE COMPLEATE SHOPPE Most rockhounds have a shop or a place that acts as one. Most of us have it as well equipped as we can afford. But, how well equipped is it for safety? Perhaps the best way to understand what’s needed is to compare our shop with an industrial chemistry laboratory. Let’s look at lab equipment. The lab must, by law, have a suitable fire extinguisher readily available. Most often, that means it is hanging on the wall next to the "front" door. The lab will have a safety hood where air is drawn from the lab proper and exhausted outside and high off the ground. The lab will have safety cans - cans that have a spring-loaded lid to keep them closed and will be made of non-sparking material. The lab will have all-metal boxes or shelves or cabinets. The lab will have a non-skid floor with matting if the floor is likely to get wet. The lab will have safety glasses, face shields, ground fault electrical outlets, safety buckets, rubber and plastic gloves, safety waste cans, tongs and other tools for moving hot materials, an eye fountain for emergencies, a nearby emergency shower, dust and filter masks, a first aid kit, and other specific safety devices for the operations going on in the lab. AND MORE! Well that’s something, but what does it have to do with a rockhound’s shop? Maybe nothing. Most likely, a whole bunch. If you have any flammable liquids around, you should have them in safety cans stuff like alcohol, acetone, methyl-ethyl ketone, gasoline, kerosene. Actually, the lab will have the absolute minimum possible inside with the rest stored outside in a fireproof metal cabinet. Safety cans mean no spills. No spills means no fires. Other flammable stuff - glues and the like - should be stored in tightly closed metal containers (a metal fishing tackle box). Bottles of acids should be stored in safety buckets - they’ll contain the acids if the bottle breaks. Fuel bottles, such as acetylene or propane bottles, are securely chained to prevent their turning over and, perhaps, breaking off the valve. (Talk about a rocket!) The safety hood in a lab will prevent the buildup in the lab of any flammable or toxic material in the air. You should copy the principle in your shop. Work with ventilation. Fresh air should come first to you, then to whatever you’re working on and then be exhausted (A floor fan hung in a window often works well.) or blown away if you’re outside. The personal safety stuff - gloves, masks, safety glasses, tools, ear protectors and so on are all cheap and all available at WalMarts and most hardware stores. Spares for guests should be on hand. The fire extinguisher and first aid kit are musts. The ground fault electrical outlets certainly should be used. The non-skid floor mat is needed in many rock shops. The proper tools for the job in hand are a good safety measure. We might not be as well equipped as a commercial lab. The closer we can come the safer we will be. We should indeed consider all the same safety factors and what we can do to be safe. by Mel Albright - AFMS Safety Chairman Tain’t So "ALL THAT GLITTERS IS NOT GOLD" In Gilbert and Sullivans operatta H. M. S. Pinafore, Buttercup reminds us that "all that glitters is not gold" and that "jackdaws strut in peacock feathers". We should keep her advice in mind when we read "hints" in our own and in exchange bulletins. These ideas come from people with good faith, but often little or no scientific background. Editors copy from each other with little effort to evaluate the ideas. Many feel as I did when I started - "If it didn’t work, it wouldn’t have been suggested." So - they may be short-cuts to disaster. A few that I have seen include: "Use permanent automobile anti-freeze in you saw instead of cutting oil." I doo not know what this would do to your saw blade or how well it would lubricate. I do know that ethylene glycol (antifreeze) is a toxic material. It is bad for your health and for that of any pets you may have around. Skin exposure and breathing of the mist created by the saw would both be bad for you. This hint is a real loser. DO NOT DO IT! "Use kerosine as a cutting oil in your saw." Again, this is a bad idea. Kerosene is A FUEL. It is less volatile than gasoline and more volatile than diesel oil. It doesn’t ignite as easily as gasoline, but it will ignite from sparks and heat. You could end up with several gallons of fiery fluid running around the floor. DO NOT DO IT! "Heat a cab and some wax in a microwave oven for fast dopping." Do you remember Mt. St. Helens? The big explosion that occurred? That came from superheated steam. You can create a smaller version of the same explosion in your microwave if you follow this hint. All rocks have water in the pores inside. Microwaves work by heating water. The steam formed can create unbelievable force when it is confined as in the rock pores. When the rock fractures, there will be lots of shrapnel flying around. DO NOT DO IT! Generic "mix this with that to do this" hints. When two chemicals are mixed, there is often a reaction. Some reactions are quite vigorous and release lots of energy. Mixing acid and water is a sample (see "superheated steam" above). AAA - always add acid to water. Other mixing reactions release toxic fumes. An example is porcelain cleaner and laundry bleach. They release chlorine gas. If you try one of these hints, start outdoors and with limited quantities. Or - DO NOT DO IT! Remember - some good sounding ideas are really, really bad. Read them with caution and, if you’re not familiar with the material’s properties, ask someone about them. by Mel Albright - AFMS Safety Chairman "Safety" glasses ARE YOUR SAFETY GLASSES REALLY SAFE? by Mel Albright - Chair, AFMS Safety Committee We are constantly reminded to wear ‘safety’ glasses. So, we tell the optical shop or the eye doctor that we want safety glasses. Or, if we don’t wear prescription lenses, we buy ‘safety’ glasses from somewhere. Then, feeling virtuous, we proceed to work away. Did you know that you are NOT very well protected? WHAT! But they said these are safety glasses. Well, they are and they aren’t. Several years back, the U. S. government passed a law that all glasses sold must be "safety’ glasses. The law’s meaning was that, if the glasses break, they will shatter into small, non-pointed pieces and form no knife-like shards that might puncture the eye and go deeply into the eye. This is the standard for safety glasses. In industry, ‘safety’ glasses mean much more. In addition to breaking properly, they are designed to be break resistant. That is, if something hits them, they will tend to stop it instead of just breaking. Even more, industrial safety glasses may be designed to stop liquid splashes from hitting the eye - not just straight on, but also from the side. So, we rockhounds should ask for and get industrial grade ‘safety’ lenses and frames. It is that resistance to breakage that offers us the most protection. I’ll admit safety glasses are not particularly attractive, but that’s not their purpose. Personally, I like a face shield in the shop instead of glasses. It is more protective, cooler, and restricts your vision far less than glasses. Actually, a face shield would be better on field trips, too. But it sure isn’t as handy. Whichever, be sure to wear one of them when appropriate. AFMS Newsletter - Vol 95, No. 6 August 1995 First aid kit THE PERFECT? LIGHT-WEIGHT FIRST AID KIT by Chris Rylands - Bellevue, WA [Did you know rockhounds field trip the internet, too? Recently, the rockhound e-mail exchange group had an interesting discussion. It started when Chris Rylands (BRIOSA@aol.com) attempted to describe the perfect light-weight first aid kit. See if you agree with Chris or perhaps you think of something that should be added. - Mel Albright, Chair, Safety] The idea of this kit is small and lightweight but yet an all around life saver. >>One of those blue plastic eye cups if you need to wash out your eye, and an eye patch and eye ointment for infections. Most rockhounds do not bother using their eye protection.

First dig a 3 ft x 2 ft deep hole. Place one bag in the bottom center of the hole, shape it as a cup. Lay the plastic suction tube in the cup bottom and up and out of the hole. Now cover the hole with the other plastic bag one layer thick. Totally seal the circumference of this hole and bag with sand. Now place a stone in the center, as to made a depression in the bag over the cup. As the humidity condenses on the top bag the moisture beads up and rolls to the drip point and lands in the cup. Then you suck on the straw.

Spiders LIONS AND TIGERS AND BEARS? - HECK NO! ARACHNIDS!!! Mel Albright, Chair, Safety Arach-what? Well, Spiders, if you weren’t scared by the motion picture starring a few million of them. Spring and Fall are prime times for people and spiders to interact - not always to the spiders disadvantage. Spiders love warm, indoor places - quiet ones - and wood, brush, and rock piles. Shoes, seldom used closets, rock storage, under tables and chairs, outdoor stone piles, wood piles (like firewood), debris piles (like from the garden or yard), unused cabins, laundry piles, and the like are the domain of the three spiders that people should look out for. The three are the black widow spider, the fiddleback spider, and, one that may be new to you, the hobo spider. The renowned black widow is a hairless shiny black spider with a red or yellow hourglass on her belly. (Yeah, I know, I don’t wait to turn them over, either.) The females are 12 to 18 mm. in body diameter, so they aren’t too hard to spot - except they place their nests under things and out of sight. They rarely kill anyone but their bite may leave you thinking they have. From 10 minutes to an hour after a bite come muscle spasms, burning, cramps, nausea and dizziness. Vomiting may also occur. Stone piles, log piles, rarely used sheds, and other debris piles are favored by this one. (In the old days, it was on the underside of the outhouse seat - especially dangerous for men.) The fiddleback or brown recluse is a pale brown to reddish with a dark violin shape on its back. Its body is 8 to 14 mm. It is the most dangerous spider. Its venom is stronger than pit viper snake’s venom. Its bite may cause fever, chills, headache, and - sometimes - death. The bite may also ulcerate and cause tissue loss that doesn’t heal - even causing permanent damage. If you find a bite with a reddish spot in the middle and a whitish halo around it, go directly to medical help. (I’ve felt this one, so I can say the bite also hurt like heck.) Basement crannies, clothes piles (even in bed with you!) , and other dark places are preferred spots. (Mine was under my riding mower seat with the mower in a dark, rarely used barn.) The hobo spider is an import and has spread from ports. It is considered the most common indoor spider in the U.S. They are brown and their body is from 10 to 15 mm. They attack where other spiders run. Their nests are funnel shape. Their bite leaves a spot and a halo like the fiddleback’s bite and can cause 2 to 6 inch blister that take up to 6 months to heal and sometimes require surgical removal before healing is possible. The bites may also cause short term memory and vision loss, nausea, headaches, and fatigue. Rarely, the bite kills. They are most likely to move indoors with you when the weather starts changing in the fall. In the fall, they also mate and are particularly touchy and aggressive. They like wood piles, crawl spaces, barns, haystacks, and undisturbed clutter. All three occur in every continental state. The fiddleback is most common in the south and the midwest. The hobo is very common in the Pacific northwest. The Black widow is everywhere except Alaska. If you are bitten: Light bites require light use of ice packs and cortisone cream. Bulls-eye bites or those with other symptoms require immediate medical care. If you’re bitten, try to kill the spider and take it with you for identification.

This point was driven home for me many years ago when a young man on my production team had an eleven hundred pound steel roll from a toilet paper rewinder fall on his foot. The resulting blow caused his safety shoe protective cap to explode and thus expend the momentum from the roll, and produced a nasty looking and painful set of blood blisters and black and blue marks on the top of his foot, but no broken bones or loss of toes. Today's safety shoes are available for many functions, in many styles, and are quite affordable. In selecting a pair of safety shoes, consider what you will be doing in pursuit of our wonderful hobby. If your passion is the art of the lapidary, slabbing rocks, or the sale or display of rocks, minerals, or fossils, a nice pair of low cut safety shoes with protective tips (steel or nonmetallic), such a sneakers, oxfords, penny loafers, even slip ons, may provide you with the protection you need from a dropped specimen or hand tool. If you attend field trips or walk over rugged terrain, you should consider safety shoes that support the ankles and provide protection from sharp sticks, thorns, stones, abrasion, temperature, moisture, and walking impact. A pair of waterproof boots that lace over the ankles would be ideal for this purpose. Higher lacing boots would be advised for areas where thorn bushes, cactus, or snakes are found. Full grain leather or waterproof safety shoes will provide moisture protection for normal weather encountered, however for extensive wear in water, such as creeks, beaches, snow, mud, etc., I strongly recommend that overboot or waders be used over the safety shoes. The soles of safety shoes should provide solid grip traction, but not clog or chew up the trail. A properly fitted set of safety shoes with a liner and footbed inside will provide ventilation, insulation from heat or cold, protection from rubbing, and absorption of walking impact, and all day comfort. The wearing of wool socks (or other materials recommenced by the manufacture) in the safety shoes will wick perspiration away and protect the feet from extreme temperatures and disease. Tucking the bottoms of your trousers and shoelaces into the top of the boots will keep insects, stones and other undesirable items from getting up your pantlegs and down into your safety shoes, and will reduce the chance of you tripping over your shoe laces. Please note that general issue army boots do not have protective tips and thus are not safety shoes. Only certain army personnel, like mechanics, are issued safety shoes. Today safety shoes are available from most shoe stores. Tell your shoe store salesperson what your needs are, and find the style that you like. You may find that you are wearing them everyday for safety. Hammer Safety Safety First by Bill Klose, EFMLS Safety chairman March 2000 EFMLS News Hammers used by rock hounds come in every size, type and construction, and include rock hammers, bricklayer's or mason's hammers, blacksmith's or sledge hammers, machinist's peen hammers, jeweler's hammers, setting hammers, soft face hammers, lead or copper faced hammers, trimmer's and welder's hammer's, as well as a variety of mallets, such as rawhide, rubber, and tinner's. I have even seen napping hammers (a 3 pound high carbon steel hammer with tapering faces used for forming stones during road construction or similar stone work) and railroad track mauls (used for driving railroad spikes). As it is hard to anticipate what a rockhounds "favorite weapon" will be, I though I would present a list of general hammer safety practices followed by the proper use of some of the more common hammer types. Always select the proper type, size, and weight of hammer for the job. Always wear eye protection. Always strike a hammer blow squarely, avoiding glancing blows and over and under strikes. The hammers striking face should be parallel with the surface being struck. When striking a chisel, punch, or wedge, the striking face of the hammer should be 3/8" larger than the struck face of the tool. Both the striking hammers face and the struck face of the tool should be free of oil. Do not strike another hammer with a hammer. Do not strike a harder surface with a hard surface hammer. Never use a hammer with dents, cracks, chips, mushrooming, or excessive wear. Replace the hammerredressing is not recommended. Replace worn or damaged handles. A qualified individual should replace hammer handles. Most hardware stores will replace hammer handles for a nominal fee. They can also provide a rubber sleeve for sledge hammers, which will prevent handle damage just above the head. Bricklayer's or mason's hammers are designed for setting or splitting bricks, masonry tile, and concrete blocks. Never use them to strike metal or drive tools such as chisels. The blade of a bricklayer's hammer should be kept sharp by redressing at a 40 degree angle with a bench grinder. Keep the metal cool while grinding by quenching often in water to protect the metals tempering. Hand drilling hammers are used with chisels, star drills, punches, and hardened nails. Never use common nail (claw) hammers for striking metal, such as chisels, as they are designed for driving unhardened nails and their shape, depth of face, and balance make them unsuitable for this use. Machinist's peen hammers (ball, cross, or straight) are designed for striking chisels and punches and riveting, straightening and shaping metal. Blacksmith's or sledge hammers are designed for striking wood, metal, concrete, or stone, depending on size, weight, and shape. When using a hammer, grip the handle near the end where it is designed for gripping and will give you the best control and impact with the least effort. Watch your hands, shins, and feet. It may be advisable to wear gloves, long sleeve shirts, and high lacing safety shoes to protect from flying debris and sharp shards if the situation warrants it. When storing hammers for a period of time, lightly lubricate metal parts, but wipe any oil or grease from rubber mallets or rubber handle grips to prevent damage to the rubber. So get out there and hammer up a storm, safely. Safety with Common Hand Tools in the Field SAFETY FIRST by Bill Klose EFMLS Safety Chairman April 2000 EFMLS News Last month we covered hammers. Now lets look at other hand tools commonly encountered in the field. Chisels and drills are used with hammers. Flat cold chisels are used to form and cut cold metal, so we should use brick chisels (double beveled point with an included angle of 80 degrees) and brick sets (single beveled point with an included angle of 45 degrees) to split rocks. Star drills have all cutting edges to an included angle of 70 degrees. Hold chisels or drills with a loose fist, keeping the fingers relaxed in order to minimize the chance of being hit by a glancing blow. A sponge rubber pad forced over the chisel or drill above the hand may also protect the hand from a glancing blow. If some one else is holding the chisel or drill, it is best to use a set of tongs or a chisel holder to guide the chisel. Gloves are always recommended for both individuals to protect from glancing blows and flying chips. The following safe practices apply: Protect cutting edges by installing protective covers. Store in racks where they may not be chipped or broken. Regrind broken or chipped chisel edges before using. Remember to cool in water often to protect the temper of the metal. Drill cutting edges should be hand filed. Replace chisels and drills with mushroomed heads to prevent shards of metal from breaking off and causing injury. Lubricate with light oil before storing. Crowbars, pinch bars, and wreaking bars are favorite tools of the rock hound. Be sure to use the proper size for the job, with a point or toe that will grip the object to be moved and a heel that will act as a pivot or fulcrum. Use of a block of wood under the heel may also keep the bar from slipping and causing hand injuries. Store bars secured upright so they wont fall or cause tripping hazards. Never hit a bar with another tool and do not try to pry an item that will cause the bar to bend. Knives are responsible for more disabling injuries than any other hand tool according to the National safety Council. Use knives only for the purpose intended, not splitting rocks with a hammer. Keep the knives blade sharp and cut away from the body, avoiding jerky motions. Use knives with retractable blades whenever possible. If the item to be cut is held in the other hand, wear cut resistant gloves. Always wear a sheathed knife at the hip towards the back, never on the front part of belt. This prevents severing an artery or vein in a leg in case of a fall. Wipe knives with a separate cloth with the sharp part of the blade turned away, not on clothes of with fingers to prevent cuts. Wash knives separate from other utensils. When not in use keep knives in sheaths or racks and guard their edges to protect people as well as the knives edge. For long term storage apply a rust preventative compound on all metal parts and place in a dry spot. Avoid horseplay such as "fencing" when using knives and have plenty of room so you wont bump into anything. The 18" machete is used to cut tall grass, vines, and small brush and is heaviest and widest near the pointed end and has a handle shaped to fit the hand. When using a machete, always make sure no one is close enough to be injured before swinging the tool, and always clear the swing path so as not to deflect the blade. Do not use a dull or defective tool and store properly in its sheath when not in use. For prolonged storage coat metal parts with light oil. Axes are designed for cutting, felling, trimming, notching, and splitting wood and soft material. A narrow blade is for hard wood and a wide blade is for soft wood. A single bit axe may also be used for driving wooden stakes, not chisels and drill bits. Never strike an axe against metal, stone, or concrete. Never strike with the side of an axe. Never use an axe with a worn or damaged handle. Use steel wedges for splitting wood and use a sledge hammer or maul for driving a steel wedge, not a single bit axe. Keep axe blades sharp - a dull blade may glance back and cut the user. Always wear safety shoes, safety glasses, and durable pants. Before swinging an axe, ensure you have a path clear of vines, brush, etc., with no one standing close. During swing, let hand slide down the handle towards the other hand near the end. Have your weight evenly distributed with knees set but not tense. The body should be relaxed and free to swing and bend at the waist. For a right handed person, the left foot should be closer to the work. Protect axe blades with a sheath or metal guard. Carry axes at side-single blades pointed down. Axes, like knives, should be kept sharp by honing. Double bevel mattlock and pick mattlocks are designed for digging and cutting. There use and safe practices are similar to that for axes. Long handled shovels are used for digging in open areas and D handled shovels are for light digging in confined areas. The spade is for heavy digging in confined areas. The post hole digger is used to bore holes for posts, explosive charges, etc. Shovel blades should be kept well trimmed and the handles in good shape and free of splinters. Wear heavy safety boots with sturdy soles and use the ball of the foot, not the arch, to press the shovel into the ground. If the instep is used and the foot slips off the shovel, the sharp corner of the shovel may cut the shoe and the foot. Keep legs well separated with spring in the knees - the leg muscles should take much of the load while shoveling. Dip the blade in water often or coat the blade with wax or grease to keep the shovel free of sticky material and caking. Treat the wooden handles with linseed oil occasionally to avoid cracking and splinters. Store shovels against or hang on the wall in a rack or shovel box. Lyme Disease and Some Other Hazards Found where Rockhounds Roam SAFETY FIRST by Bill Klose EFMLS Safety Chairman Submitted for the May 2000 EFMLS News With the onset of spring the rock hounds heart turns to the field and rock hunting. The renewal of spring with all it's beauty and bounty, also brings out the reptiles, insects, spiders, centipedes, scorpions, and poison oaks, ivys, and sumacs. The dangers posed by these creatures and flora of nature are well documented in the AFMS "Safety Manual" which I highly recommend club members review prior to heading out for the 2000 collecting season. The Safety manual is available in your local club library or from the EFMLS Supplies Coordinator Ned Reynolds for $l.50 plus $ .35 Shipping and handling at 37 Broadway, AMENIA NY 12501-0394. Some additional data has come to light since the AFMS "Safety Manual" was published that I would like to review with you here. The wood and deer ticks, which commonly occur in thick woods or tall grass, have been long associated with Rocky Mountain Spotted Fever, but in recent years their bite has also been linked to Lyme Disease and several other severe illnesses, including encephalitis (brain inflammation), Ehrlichiosis, and Babesiosis. Lyme disease has been reported from all U. S. States except Montana, since it was first identified in children in Lyme, Connecticut in l975. The symptoms of the disease include an expanding red rash around small hard white lumps, arthritis, fever, chills, aches, enlarged lymph glands, and joint swelling. Not all of these symptoms may occur, which makes diagnosis difficult. Several weeks to several months later symptoms may include facial paralysis, joint inflammation, heart palpitations, memory loss/difficulty concentrating, and changes in sleep habits or mood, so early treatment by a physician is a must. But not to worry. On the positive side, the illness is limited to warm weather periods (April through September), not all ticks will be carrying the disease, and even if you are bitten, the tick usually must be logged in your skin for 36 to 48 hours to actually pass on the bacteria that causes Lyme Disease. So prevention of tick infestation by not allowing ticks a point of entry through your clothes, the use of tick repellent in areas where they are known to occur, staying clear of tall grass and dense woods, frequent inspection of you and your pets for ticks, prompt and careful removal and disposal of ticks, and washing of hands after handling ticks (do not crush between fingers to kill) will ward off the possibility of contracting tick-born disease. There is no immunity built up to Lyme disease after having had it, but it cant be passed from one person to another. A vaccine has been developed and is given as three injections in a 12 month period, but is not recommended for children or the elderly. Added to the list of critters in the AFMS "Safety Manual" is the caterpillar, some species of which have poisonous spines or hairs, which when touched can cause skin irritation, itching, redness, swelling and a raised rash. Wash well after touching a caterpillar. Animal bites. Most animal bites are caused by household pets, however bites from wild animals can be especially dangerous because of the possibility of being exposed to rabies. Bites that only break the skin should be washed thoroughly with soap and water and covered with an antibiotic cream and clean bandage. If you haven't had a tetanus shot in the last 10 years, get a booster shot. A bite where the skin is badly torn or that creates a deep puncture and is bleeding should have pressure applied to stop the bleeding and be shown to a doctor as soon as possible. If there are signs of infection or you suspect the animal may have rabies (displays odd behavior, is foaming at the mouth, etc.) see your doctor immediately. Because we EFMLS rock hounds fan out all over the U. S. to collect, I am adding some Western items for your consideration. Cacti. If you are struck by cactus spines, pull them out with a tweezers or fine toothed comb, being careful not to break them off in the skin. For fine spines use scotch tape or apply a thick layer of household glue, letting it dry, then slowly peel it off, taking the spines attached to it. Apply an antiseptic to the punctures and watch for any infection from fungus on the spines. Valley fever is well known to fossil collectors at Shark Tooth Hill, Kern County, California, but is also known to occur across the Southwest to Texas and into Northern Mexico. The disease may last for years but once recovered, a person is immune. Valley fever cannot be transferred from one person to another and at this time there is no vaccine available. Valley fever is a highly infectious fungus disease which occurs in the soil and is inhaled as airborne spores into the lungs. Most cases occur during dry periods following periods of heavy rain. It produces flu like symptoms, and in rare cases serious fever and scarring of the lung tissue. It is occasionally fatal or causes meningitis. The cure is bed rest and possibly antibiotics. Pulmonary Syndrome Hantavirus. This disease occurs in rodent urine, feces, and saliva in the Southwestern U. S.. It is primarily carried by the deer mouse, but has also been detected in pinion and brush mice, and the western chipmunk. The symptoms include a high fever, backache, respiratory distress, excessive urine production (polyuria) and abdominal pain with possible hemorrhaging of the capillaries. Recovery is in three weeks or kidney failure. Death may result from the loss of blood. Person to person transmission and transmission by insects or cats and dogs is not known to occur. Protection includes staying away from areas with heavy rodent infestation and use of HEPA (High Efficiency Particulate Air) respirators when having to enter known areas of infection or heavy rodent infestation. A fairly rare disease in the U.S. but with a high mortality rate and well worth being aware of. There is no need to panic and cancel collecting trips because of all the potential pitfalls out in the field, but it is important to be aware of them and what to do if the need should arise. Safety in the Heat and Sun SAFETY FIRST by Bill Klose EFMLS Safety Chairman Submitted for the June 2000 EFMLS News Now that the warmer weather is with us, so are the dangers associated with sunlight and hot temperatures. Exposure to the sun for excessive periods of time can cause sunburn, premature aging of the skin (leathery, rough and wrinkled), and the long term risk of developing skin cancer. Eye exposure to Ultraviolet (UV) rays can also cause cumulative destructive changes in the structure of the cornea and lens of the eye. Visible light, if too intense, can cause eye strain, headache, and destroy eye retina tissue. Infrared radiation transmits heat to the eye, causing discomfort, and if prolonged, can contribute to the development of cataracts. Sunlight reflected from sand, snow (leftover from winter), and water can also increase damage to the eyes and skin. To avoid exposure to the sun, wear long sleeves and pants (not shorts!) of dense cloth, hats, sunglasses with UV protection, and a non-allegetic, waterproof, sunscreen with a Skin Protection Factor (SPF) of l5 or more on the remaining uncovered skin. Reapply the sunscreen every two hours. Protect your skin and eyes even on cloudy days which can be when you will receive your worst exposure. UV damage can be more sever at higher elevations where the air is thinner and filters less out of the sunlight. In exceptionally hot parts of the country, such as the Desert Southwest, avoid exposure to the sun between 10 AM and 3 PM when the suns rays are the most intense. Some newspapers and TV stations forecast a Sun Intensity Index with the weather, which tells how many minutes it takes for fair unprotected skin to redden. This time is then multiplied by the SPF of your sunscreen to give you an estimate of how long you can delay becoming sunburned. If the Index is not available and you usually sunburn in 20 minutes, than multiply the SPF (15) and you should be protected for 300 minutes or 5 hours before you sunburn. Recent studies have shown that sunscreen does not protect against skin melanomas, a serious form of skin cancer, and that serious sunburns can lead to skin cancer 10 to 30 years later. Do not believe the myth that a sun tan will protect your skin from sunburn. Effects of heat and humidity on the body. The core of the human body works on an optimum temperature of 98.6F + or - 1.8F (Internal organs, cavities, not skin). Heat cramps, heat exhaustion (or prostration) and heat stroke may occur if the core temperature rises above this optimum temperature. A persons ability to think and reason may also be impaired. The body has its own internal mechanisms to maintain the optimum core temperature described by the equation: Hs = Hm +/- Hc +/- Hr - He Hs = Stored Heat Hm = Heat gained due to Muscular Work (Metabolic activity) Hc = Heat gained or lost by convection from the surroundings Hr = Heat gained of lost by radiation from the surroundings He = Heat lost by the evaporation of sweat From the equation you can see that decreasing activity, temperature, the amount of radiated heat and increasing evaporation rate all will contribute to the decrease of core body temperature. This means that staying out of direct sunlight and heat or taking frequent breaks in a shady, cool, or air conditioned place, will decrease the chances of developing heat disorders. The intake of fluids containing salt (at least a pint an hour), such as sport drinks, or water and salt pills, will also help the body control core temperature. In hot humid weather, especially above 97 F, it is best to stay indoors and avoid all strenuous activity, as the body can not sweat enough to properly control core temperature. Heat cramps can be caused by muscle exertion during hot weather and are characterized by sudden sever cramps of the skeletal and abdominal muscles, excessive sweating and thirst. If you should suffer these symptoms, rest in a cool spot, take a salty drink, and message the cramped muscles. Heat exhaustion or prostration is caused by the body running out salt and/or water. The symptoms may include profuse sweating, with pale, moist, cool skin, headache, weakness, dizziness, loss of appetite, heat cramps, nausea (with or without vomiting), urge to defecate, chills ("goose flesh"), rapid breathing, tingling of the hands and/or feet, dehydration, a low grade fever (99 f to l02 F) and confusion. Heat stroke is caused by profound disturbance of the body's heat regulating mechanism due to prolonged exposure to the sun, high temperatures, high or low humidity, and lack of air circulation. Symptoms include red (flushed) dry skin, headache, dizziness, nausea (Stomach pains), confusion, weakness, loss of consciousness, convulsions, weak and rapid pulse and breathing, a high fever (104 f to 106 F) and low blood pressure due to shock. To treat heat stroke and heat exhaustion, move the victim to a cool spot (air conditioned and with a fan if possible), lay on the back with legs elevated, loosen tight clothing, and place cool compresses on the forehead, neck, and underarms. Water can be sprinkled on the victim, and if conscious and not vomiting, l teaspoon of salt dissolved in a quart of water can be administered by mouth at the rate of 4 ounces every 15 minutes. If the symptoms persist or the victim is unconscious, seek medical attention or transport to a hospital immediately while continuing treatment.

Pliers and File Safety SAFETY FIRST by Bill Klose EFMLS Safety Chairman Submitted for the September 2000 EFMLS News With the coming to the end of the collecting season it is now appropriate to look at shop hand tool safety. A few of the field hand tools, such as hammers, chisels, and knives, are also commonly used by rock hounds in the shop, but will not be reconsidered here. A commonly used group of tools are the pliers and tongs. Slip joint pliers, which include the well known water pump pliers, have serrated jaws with a rod-gripping section and are used to hold objects. The slip joint accommodates objects of different sizes. These pliers may also have a cutting edge for cutting soft wire and nails, however cutting large or hard items will spring the jaws. Arc joint pliers are similar, but may have straight or curved jaws and will accommodate a larger variety of object sizes. The tightening of bolts or nuts with slip joint or arc joint pliers is not recommended and will usually result in damage to the nut or bolt and may lead to damaged knuckles when the pliers slip. Use wrenches for tightening nuts and bolts. Vice grip pliers are designed to provide a tighter grip but are still not to be used to tighten nuts and bolts. Parallel jaw pliers are designed to hold flat surfaced objects such as sheets of metal. Flat nosed pliers and round nosed pliers have a fixed pivot jaw and curved handles and may or may not have insulated grips. The flat nosed pliers may have smooth or serrated jaws and are designed to bend light sheet metal or wire. Round nose pliers are used to make loops in soft wire. Diagonal cutting pliers have a fixed pivot and curved handles that are offset from the jaws about 15 degrees so as to provide the operator enough knuckle clearance while making flush cuts. These pliers are designed for cutting small light pieces of wire, cotter keys, etc. and should not be used to hold or grip items. When cutting, restrain the piece to be cut off so it will not become a missile hazard. End cutting pliers or nippers are used to cut off wire flush to the working surface, thus keeping fingers away from the wire ends. Hand shears are made with straight or curved cutting blades and are used for cutting sheet metal. Shears are made for right-handed operators so that the cutting line is always in full view for accuracy. Straight blade shears are used for cutting straight lines and curves, while curved bladed shears are used for cutting short straight lines and curves and small intricate designs. When using diagonal pliers, end cutting pliers, or shears, keep fingers away from the jaws and cutting edges and always wear eye protection. Do not attempt to cut heavier material than the tool is designed for. Do not use plies or shears as hammers or pry bars. Keep shears sharp with an oil stone or file. Grinding is not recommend and shortens shear life. Keep pliers and shears clean and lubricate the pivot point with a light oil. Store in a dry location on hooks or a shelf, protecting the cutting surfaces from contact with other tools. A thin coat of oil can be applied to protect from rust. Do not remove insulation from handles or oil insulated handles. Replace pliers that have broken handles, cutting edges or jaws. Straight-lip flat jaw tongs have a fixed pivot point, two straight jaws and long straight handles and are used for placing hot items into and picking them out of pickling solution. Files come in many types and sizes and are used in metal smithing and soap stone carving. Some general safety precautions for using files are: 1. Never use a file without a securely attached file handle (unless it is a swiss pattern type). 2. Do not oil files which will cause the file to slide across the work, preventing fast cutting. 3. Do not use files for anything but filing. 4. Clean files often as clogged files will scratch the work. Always use a file scorer and file cleaning brush to clean a file-do not strike against another tool or object to remove filings. 5. Store files in a file rack or box so that the file faces or edges do not touch each other or other tools. Do not store files with lubricants on them. Wrap each file with a waterproofed barrier wrapping paper. A variety of other hand tools can be found on the rock hounds work bench and each has it's own operating and safety instructions. Work Safe! Grinding, Polishing, and Buffing Machines SAFETY FIRST by Bill Klose EFMLS Safety Chairman Submitted for the October 2000 EFMLS News Now that the field collecting season is about over for many of us, we turn our attention to processing the summers "harvest" of goodies. For many of us this means using our lapidary equipment, especially the rotating grinding, polishing, and buffing machines. Abrasive disks and wheels are made of bonded abrasive and are usually spindle mounted by a center hole to the grinding machine. Polishing wheels are wood faced with leather, stitched canvas, or similar materials. A coat of emery or other abrasive is glued to the periphery of these wheels. Buffing wheels are made of disks of felt, leather, canvas, or linen to which a coat of mild abrasive, such as tripoli, can be applied to the periphery. Some lapidaries will also have brush or scratch wheels made up of protruding wires of different types, sizes and lengths. Make sure that the machine to be used is heavy duty enough to accommodate the size and type of wheel you will be using and that the surface speed of the wheel peripheral is within the operating range recommended by the manufacture. If you do not know the recommended speed of a grinding wheel, operate below 2500 surface feet per minute (sfpm) to eliminate the risk of the wheel disintegrating and causing damage to the surrounding equipment or personal injury. Polishing and buffing wheels are operated at a speed of 3,000 to 7,000 sfpm with 4,000 sfpm a good speed for most purposes. All machines should be connected to a power source of the proper rating for the machine and grounded. Circuit breaker or Ground Fault (GFI) circuit breaker protection are highly recommended. The shut off switch or plug should be within reach of the operator in a dry place protected from any spray from the machines coolant. Stand to the side of a grinding machine when starting up and allow at least one minute of warm up time before starting to grind. Always use coolant when the wheel is turning and while grinding, but never allow coolant to flow over a wheel that is not turning, as the coolant may collect on one portion of the wheel and throw it out of balance, which could cause the wheel to disintegrate upon starting. Before stopping a wheel, discontinue applying coolant and run the wheel until it dries evenly, thus maintaining balance. Only the periphery or circumference of standard grinding wheels are designed for grinding-never grind on the sides of a grinding wheel. For bench and floor stand grinding wheels, the peripheral guard should enclose the wheel and spindle as completely as possible, not to exceed 65 degrees of wheel circumference exposure. The guard should be adjusted to maintain a maximum opening between the top of the guard and the grinding wheel of 1/4 inch (6 mm). Safety guards should also cover any exposed arbor ends and drive belts. A work rest should be installed at the height of the horizontal center plane of the machines spindle no more that 1/8 inch from the grinding wheel to prevent work from becoming wedged between the rest and the wheel, resulting in the wheel breaking. this distance should be checked often as the wheel wears. Adjustment of the rest and the guards should only be made when the wheel is stopped, to avoid contact with the moving parts and resulting damage to the equipment and possibly fingers. Grinding work should be done near the center plane of the wheel and moved back and forth across the face of the wheel to produce even wear. Do not force the work and take too heavy of a cut. Do not hold small pieces of work against a wheel with bare hands. Small pieces should be placed in a simple jig or fixture or attached to a dop stick to protect the fingers from injury. The floor in front of the grinder or polishing machine should be of rough cement or a non slip rubber mat to prevent falls on the wet surface. Abrasive wheels that are out of true or unbalanced will not only produce poor work and reduced wheel life, but could cause machine damage or operator injury. Rutted or rough wheels can be redressed with wheel dressing tools. The wheel dressing tool should have a hood guard to protect the operator from flying particles from the wheel or broken cutters and should be used with a rigid work rest set close to the wheel. Prior to use, inspect star dressers for worn shafts and disks. If using a diamond dresser, apply to the face of the wheel at the center plane of the wheel or slightly below the center plane, never above. Never use a lathe cutting tool to dress a grinding wheel. The wheel dresser should be moved across the wheels face while holding the heel or lug firmly against the edge of the tool rest. Apply moderate pressure evenly and slowly. Before and after dressing a grinding wheel, round off the grinding wheels edges with a hard grinding stone to prevent the edges of the wheel from chipping. Wear a safety shield over your safety glasses for added protection from heavy particles. Wheels that are badly worn or out of balance should be taken out of service. Abrasive wheels should not be bumped or dropped during handling. New wheels and wheels that have been in storage should be inspected for cracks and other damage and should be given the "ring" test by suspending the wheel by its center hole on a peg or finger and gently tapping it on the side with a wooden screwdriver handle at 45, 135, 225 and 3l5 degrees around its circumference from its vertical center plane. A good wheel will produce a clear metallic ring of various pitches, depending on its grade and size. Do not use wheels that have been in storage longer than recommended by the manufacturer. Abrasive wheels should be mounted between matching balanced flanges that have a diameter of more than one third of the wheels diameter. Mount compression washers of blotting paper (less that 0.025 inch thick) or rubber or leather (less than 0.l25 inches thick) between the wheel and the flanges to compensate for unevenness of the wheel or the flanges. Firmly mount the wheel on the grinders spindle with a spindle end nut, but not so tightly so as to distort the flanges or break the wheel. A wheel that is loose on the spindle will run off center causing vibration. Once mounted on the machine, the wheel should be turned several rotations by hand to ensure that the hood guards and work rest have the proper clearance and that the wheel is properly centered on the spindle. Mounting procedures for polishing and buffing wheels, and brush or scratch wheels are basically the same as for abrasive wheels. When any of these wheels are moving do not touch any moving part of the machine or wheel to determine its smoothness or condition. Always wear safety glasses with side shields or goggles. Do not wear loose clothing or gloves that could get caught in the rotating components of the machine. In some cases gloves may be required for protection from some liquids used during the buffing or polishing process. Books on lapidary or chapter 12 of the AFMS SAFETY MANUAL on lapidary safety and manufactures instructions discuss these materials and there hazards. Adequate personal protection should be worn when using brush or scratch wheels, such as aprons (leather, heavy canvas, heavy rubber), leather gloves, face shields and goggles. When applying abrasive to a rotating wheel, hold the side of the cake lightly against the wheels peripheral. Where possible apply polishing compounds with a brush. If a stick is used, apply the side of the stick to the off side of the wheel, so if it is thrown, it will fly away from the wheel. Usually all operations should be done wet, however if the polishing procedure calls for sanding or polishing dry, wear a dust respirator or use a suction blower to remove any dust. Silica dust if inhaled can lead to a serious lung condition that is incurable, silicosis. The lapidary is filled with other rotating machinery, such as diamond saws, flat laps, drills, etc., etc. All of these machines are supplied with operating, maintenance, and safety instructions by the manufacture. Use all safety procedures and enjoy our hobby without pain and with all your appendages. Traveling Safety SAFETY FIRST by Bill Klose EFMLS Safety Chairman Submitted for the December 2000 EFMLS News The AFMS SAFETY MANUAL has several chapters devoted to the family car and its care prior to a trip and the car as a life saver. At this time of the year we, as rock hounds and members of the traveling public, have to consider winter driving, for most of us this means driving in the snow and ice. Prior to venturing out in winter weather, consider if the trip is worth the risk, or if the trip can be delayed until conditions are better. Winterizing the family vehicle is a must. Make sure that your brakes, windshield wipers, defroster and heater system, and exhaust are all in good condition. Check your fluids for the proper types and levels, such as winter grade oil, proper antifreeze levels and temperatures, and winter type windshield washer fluid. It may pay to have a tune-up, prior to going into winter, to avoid starting problems on the colder days. Make sure that tires are properly inflated and the tread condition is good per the manufacture's instructions. Make sure the battery has good capacity and that the battery connections are clean and tight. Have all belts and hoses inspected. Have the brakes adjusted if required. Make sure all lights are in working order, including the emergency flashers. A number of items should be carried in your vehicle in case of emergency. These include the standard jack, lug wrench and spare tire or "donut", window scraper, flash light with spare batteries, matches in a watertight container and a "survival" candle, emergency flares and reflective triangle, first aid kit with pocket knife, jumper cables, adequate blankets and or sleeping bags, set of tire chains, traction mats, sack of sand for traction, and ice melt, small shovel and snow shovel, medicine, energy food bars or dried foods, such as trail mix, and bottled water. Portable radios and cell phones with spare batteries for both are highly desirable. Extra cloths, shoes, gloves, hats and rain gear will be required if it turns colder, you get wet, or you are not dressed for the outdoors, but only for a warm car. A small tool kit that includes, screw drivers, wrenches, pliers, a tire pressure gauge, "bungy cords", duct tape, bailing wire, and a rag can be used for minor roadside repairs. Carry a pencil (or pen) and paper and a brightly colored rag to us a flag. Before leaving the house, dress warmly in layers of light loose fitting clothing. Run the defroster and heater when warming up the car, which should be driven as soon as possible to avoid damage to engine parts. Allow extra time for the trip and drive an appropriate speed for the road conditions. Keep the gas tank at least half full at all times and full at the start of a longer trip. Keep an empty clean or new gas can with the emergency supplies. Make sure the windows and lights are clear of snow and clean. Use seat belts and car seats that are properly installed in accordance with the manufactures instructions. Do not lean forward in vehicles that have air bag (ABS) systems, but try to give the air bag cover at least 10 inches of clearance to provide sufficient space for deployment. Drive with the lights on and the mirrors properly adjusted. Use proper signals while turning. Keep a safe distance from the car ahead to allow reaction time and proper braking. If driving in the snow, the best steering is in the tracks of the vehicle ahead. If you go into a skid, take your foot off the brake and gas, let the engine slow you down, and steer gently in the direction of the skid, until you regain steering control. If you have standard brakes, pump the brake petal gently until stopped. If you have anti-lock brakes, apply firm and constant pressure on the brake petal-you will feel the brake petal pulsate, which is common. Never jam on the brakes. Remember that 4-wheel drive and Sport Utility Vehicles (SUV') may have higher ground clearance which helps them get going better than other vehicles in heavy snow, but are not immune to winter conditions and have the same basic handling characteristics when braking. Some SUV's have a high center of gravity and are more prone to roll over during sharp turns. When traveling with trucks, make sure the driver can see you, by driving slightly to the left side where you can see his mirror. Remember that if you can't see his mirror, he can't see you. If you pass a truck, give him a wide berth, and turn up the speed of your windshield wipers if the road is wet or snow covered. If the road is too slippery, you may consider not passing. Do not follow a truck too closely and stay back a safe distance when at a stop light or sign-he may roll back slightly on a hill before he moves forward. If the visibility gets too bad, pull as far off of the road as possible, and turn on your emergency flashers. If you have a flat tire, need repairs or have damage to the vehicle, never try to fix or survey the problem on the highway, get as far off the road to as safe place as possible, even if it means damage to the tire and rim. If the car is disabled, put out flares or reflective triangles, and if you can't safely effect repairs, call for help and stay in the vehicle for protection from the elements and passing vehicles. Road rage should be considered during any season of the year. The best way to avoid making other drivers angry and aggressive is to be courteous, content, and considerate. When you merge, always use your turn signals and allow plenty of room. If you are cut off, slow down and give them plenty of room. If you are in the left lane and someone comes up behind, move over to the right, and let them pass. Use your horn seldom, if ever. Do not come up behind other cars with your high beams on, or tail gate. Do not make any gestures, even shaking your head, that might anger another driver. Do not make eye contact with an angry driver and give him plenty of room. It takes two angry drivers to start a fight. Get help if an angry driver is following you and trying to start a fight. Use a cell phone to call police or go to a police station or place where there are people around. Do not get out of your car or go home. Make your trip to a winter rock show or a visit with friends or relatives during the holiday season enjoyable and safe. Eye Safety SAFETY FIRST by Bill Klose EFMLS Safety Chairman Submitted for the January 2001 EFMLS News Most articles on rock hound safety invariably touch on eye safety in some form or another, whether it is protection from the sun on the way to a collecting site, protection from flying particles at a collecting site, or protection from dust, chemicals, or particles while processing the finds back in the shop. Eye hazards include, particles, mists, vapors, fumes, gases, lazer light and ultraviolet light. At once you can see that not all of these hazards are commonly encountered by most rock hounds, but some will be encountered by all rock hounds. Safety glasses or spectacles are designed to provide impact protection from flying particles and have heavier frames than normal spectacles and impact resistant lenses, usually of polycarbonate. They can be tinted to protect the eyes from lazer or ultraviolet light. As most particles enter the eyes at an angle it is recommended that they accommodate and are worn with side shields. Safety glasses with prescription corrective lenses are available, even bifocal and "multifocal". Do not use spectacles intended for protection from radiation and glare from the sun indoors where your vision may be impaired by the tinted lenses. Spectacles should be fitted to your eye and bridge size and temple length. The temples should fit comfortably over the eyes. The frame should be close to the face and supported by the bridge of the nose. Keep spectacles clean and clear of scratches. Store your spectacles in a case in a dry, clean place where they will not fall or be stepped on. Scratched or damaged spectacles interfere with vision and do not provide protection. Safety spectacles alone do not provide adequate protection for the eyes from fumes, vapors, liquids and large particles. Safety goggles provide a secure shield around the entire eye area to protect against hazards coming from many different directions and spread the force of impact over a larger area around the eye. Goggles are most effective when worn with safety spectacles and are also provided with impact resistant and tinted lenses. Goggles that are unvented or indirectly vented will provide protection from splash hazards. Goggles can be provided with fog free coatings. Face shields should be worn with safety spectacles and goggles to provide additional protection of the face from sparks, splashes, splatter, and larger particles. Never wear a face shield alone. Face shields are available with protective head gear and chemical hoods. Typical rock hound usage of a face shield would include poring hot liquids, use of acids to clean minerals or fossils, breaking rocks with hand and mechanical equipment, and dressing grinding wheels. So whatever your pleasure while rock hounding, consider what potential hazards are present and select the appropriate face and eye protection required. Frost-bite and Hypothermia SAFETY FIRST by Bill Klose EFMLS Safety Chairman Submitted for the February 2001 EFMLS News My fall fossil collecting was cut short this year by old man winter's early arrival. As in past years I didn't give up easily, and braved out into the cold and wind with the help of wisdom provided in Chapter Sixteen of the AFMS SAFETY MANUAL. It is a little late for the fall, but the late winter and early spring are blessed with some collecting days that have similar wind and cold conditions. The two problems that must be avoided are frost-bite and Hypothermia. Frost-bite is caused by the cutting off of circulation to and possible destruction of superficial tissues, especially in the extremities (hands, feet, ears, nose) and other exposed areas of the body. The wind (wind chill factor) and moisture can add to the effects of cold temperatures, even when above freezing. Symptoms of frost-bite begin as a prickly feeling on exposed areas of skin followed by numbness and waxy looking patches. In more sever cases these patches get lumpy, redden, blister, and the skin dies and falls off, or gangrene sets in. Sever pain is associated with this condition. At the first signs of frostbite, dry the affected area and cover with clothing or tuck (hands and feet) into clothing or armpits to prevent further cooling. Do not rub or apply snow to the frost-bitten area. The affected area can be placed in water a little above body temperature (not above l04 degrees F). Do not place hands under running hot water, as there will not be any feeling initially, so they could become burned. As the frostbitten area "thaws" it is normal to feel pain or a burning sensation. If blisters form, do not break them, protect them with a loose dressing and seek medical attention immediately. The best protection against frost-bite and hypothermia is to keep warm, keep moving, and keep dry. Dress in loose layers of warm, waterproof, and windproof clothing, that cover exposed areas. Warm gloves and a hat are essential. Up to 80% of the bodies warmth can be lost out through an uncovered head. The young and elderly are especially at risk, as are people who have been drinking alcohol, have diabetes or poor circulation. People taking beta blockers to lower blood pressure are especially at risk. It is best to pair up with someone who can watch for signs of frost-bite or hypothermia. Hypothermia is the loss of body temperature and can be life threatening. The symptoms are initially uncontrollable shivering with pale and numb skin. The person than behaves confused and forgetful, acts tired and wants to sit or lie down. In sever cases, the person will go unconscious, and will have shallow breath and erratic heartbeat, and than the pulse weakens and slows. At the first signs of hypothermia, take the victim to a warm, dry place and give them hot liquids (not alcohol). Prevent further heat loss by blankets, warm rocks, or a companion in bed with the victim. Get medical attention as soon as possible if the symptoms have gone beyond the shivering stage. If you aren't a cold weather collector, these same precautions apply to any activities performed during cold weather conditions. Back Safety SAFETY FIRST by Bill Klose EFMLS Safety Chairman Submitted for the March 2001 EFMLS News As I got into my winter routine of reorganizing my collections, I started to notice a little persistent lower back pain related to the constant lifting and carrying of loaded boxes of rocks and fossils. I have had extensive training in proper lifting techniques in the military and industry, however a review is always enlightening. Prior to lifting it is a good idea to consider a number of things. How heavy or bulky is the object to be lifted and carried? How good a shape are you in and have you had any back problems in the past after lifting? Many back injuries are of a cumulative type, where a repeated minor injury will flare up and become worse. How much room is there around the object to be lifted and how much room is around where it is to be deposited? What kind of obstacles are there along the transportation route, such as trip hazards, holes, overhangs, etc.? If any of these questions create a concern, or if in doubt, get help or use an aid such as a dolly, hand truck, or even fork lift. Statistics show that 80% of back injuries occur in people between 30 and 50. Be sure to utilize appropriate safety equipment such as safety shoes and work gloves when lifting. The use of back belts, as seen at some stores and outlets, has not been shown to prevent back injury according to recent studies. Prior to the lift, make sure you have adequate clearance for your hands and arms. Stand close to the load with the feet apart and the toes pointed out to provide firm footing. Bend your knees, not your waist. Grip the load firmly with a "full palm Grip". Do not place your fingers under the load. Tighten your stomach muscles and then lift head and shoulders first, and then with your back straight, use the strength of your legs to slowly and smoothly push up. "Jerk-lifting" a load will multiply the stress to the lower back. Keep the load close to your body at all times with your back upright. Never hold the load away from your body. Make sure you can see over the top of the load. If you should have to change direction with the load, move the whole body with your feet. Do not twist your body which can be especially dangerous to the back. To raise the object above shoulder height, first lift to waist height and rest on the edge of a ledge, hip or stand, and then shift hand positions, so the object can be boosted after the knees are bent. The knees should be straightened as the object is lifted or shifted to the shoulders. If the object is to be placed on a table or shelf, first set it on the edge, and then push it far enough onto the support so it will not fall. The object should be released gradually as it is set down and then pushed into place with the hands and body in front of the object. When setting the object down, keep the back straight and upright, bend the knees, and lower the object down slowly and smoothly. Don't add the weight of your body to the load. Lift safe and stay healthy in 2001. Ear Safety SAFETY FIRST by Bill Klose EFMLS Safety Chairman Submitted for the April 2001 EFMLS News Hearing loss affects about 28 million people in the U. S., about 10 million of these people received this damage, in part, as a result of exposure to loud noises. More than 20 million Americans are exposed to hazardous levels of noise on a regular basis that could result in noise-induced hearing loss (NIHL). Occupational noise exposure is the most common cause of NIHL, but non occupational exposure, such as live or recorded high volume music, airplanes, automobiles and recreational vehicles, household tools and some appliances, are also major contributors to NIHL. Very loud sounds of short duration, such as an explosion, gunfire, or loud banging, can produce immediate, severe, and permanent loss of hearing. Longer exposure to less intense levels of sound over time, exacts a gradual toll on hearing, initially without the person's awareness. The louder the level of noise, and the longer the duration of exposure, the greater the potential for damage. How can we protect ourselves from this hazard? The best method is to eliminate or reduce the level of intensity of the noise source and the time of exposure. The next best prevention method is to wear hearing protection in the form of ear plugs (disposable or fitted) or ear muffs when exposed to noise. Rock hounds are most commonly exposed to noise while in automobiles or recreational vehicles on the way to collecting sites. Some collecting sites contain industrial equipment and vehicles that can generate considerable amounts of noise. When at these sites it is best to wear the same level of protection that the workers at the site are wearing, as the employer has determined the level of protection required for his employees. Rock hounds also use hammers and even large portable gasoline engine powered diamond saws at collecting sites to recover specimens, and should protect their hearing with ear plugs and or ear muffs. Back in the shop, all rotating equipment, such as diamond saws, grinding wheels, rock hammers, hydraulic rock trimmers, etc., contribute to the noise level. Consider wearing ear plugs or muffs to prevent NIHL. Reduce the effects of noise and enjoy collecting in 2001. Vehicle Safety SAFETY FIRST by Bill Klose EFMLS Safety Chairman Submitted for the May 2001 EFMLS News The winter weather is now behind us in most areas of the United States, so the rock hounds heart turns to the field trip and warm weather show schedule. Both of these activities require the use of the family pack mule, the automobile. In order to arrive safely we must prepare the "family truckster" for the trip and then "pilot" it there safely. Prior to leaving on a trip, make sure your vehicle is in good mechanical condition. Make sure the engine is in good condition after the winter and that the breaks are in excellent condition. This may require a tune up and brake adjustment or replacement. Check the tires for wear and proper air pressure, including the spare tire or "donut". If the tires show wear, rotate them, or replace them. A wheel alignment may be prudent, if it appears that misalignment is the cause of uneven tire wear. If you are going to be traveling over long distances with out services or on rural roads, especially rutted dirt roads, it may be advisable to replace the "donut" with a full size tire. This will provide the ability to reach services that are farther away then the recommended range and speed for the "donut" and provide clearance for the vehicles body on rutted roads, especially with the loads we rock hounds are known to carry. The tires should always be fully inflated. Soft tires provide a smoother ride but will heat up and may fail in the hot summer weather. Make sure your windshield wipers are in good condition and the inside and outside of the windshield and other windows are clean. Adjust the seat headrests to the level of your ears, not to the lower area of your head or the curvature of the neck. Make sure your headlights are properly adjusted and clean. Adjust your mirrors so as to reduce the "blind zone". It may be advisable to replace the inside rear view mirror with a wider type to improve rearward visibility. Avoid buying vehicles with dark tinted windows, which can impair visibility. Ensure that the seat belts and children's safety seats are in good condition and properly installed. An oil change and lube will improve engine performance and mileage after the winter driving. Check the supplies in the trunk for bottled water, a tire iron with the lug nut key, if anti-theft lug nuts are installed on your vehicle, flashlight, emergency flasher or triangle and blanket. Extra break fluid, engine oil, windshield wiper fluid, and transmission fluid are recommended, as is an emergency tool kit and first aid kit. Make sure your cell phone is in good working order and it's battery is fully charged and a spare cell phone battery is in the vehicle, especially if relying on the vehicle for power, which would not be available in case of a vehicle battery failure or wiring problem. Plan your trip before heading out, so you can concentrate on driving and not navigating. Have the maps and guides available in the vehicle and have someone else familiar with them to aid with navigation should the need arise. Make reservations in advance and plan the trip, so each days activities will not exhaust the driver. Provide for frequent stops to rest the driver and if possible share the driving responsibilities. AARP recommends that "if you are planing to take an unfamiliar route at night, try making a trial run during daylight". Avoid driving in heavily traveled or high speed areas during rush hour and bad weather. Make sure that your prescription glasses are current and that you have both clear and dark glasses with you before you leave. Carry something to eat, like energy bars, in case you are marooned alongside an isolated highway for a period of time. Once you are on the road, keep a safe distance (three second rule) behind the vehicle in front of you. If you are going to change lanes, signal way in advance and look in the inside and outside rear view mirrors and over your shoulder before making your move, to avoid not seeing a vehicle in the "blind area" in the rear quarter area of your vehicle. When passing, provide adequate space and use your turn signals prior to pulling back over into the travel lane. Do not travel in the passing lane. Do not talk on the cell phone, eat, or engage in any other activity while driving that will distract your attention or keep you from having both hands on the steering wheel. Use your headlights one half hour before sunset until one half hour after sunrise and whenever there is poor visibility or rain. Keep the radio volume down and be alert for emergency vehicles flashing lights and audio warnings. Use your safety belts and stay at least ten inches from the vehicles air bags. If your vehicle should have a flat tire or other casualty, get as far off the pavement as possible and put out a flare, flasher or emergency triangle, so others can see you. It is better to drive a short ways on a flat to get the vehicle out of traffic danger. If it is not safe to change the tire or repair the vehicle yourself, call for help. Do not encourage road rage by making jesters, looking at other drivers, or exhibiting aggressive driving habits. If you should be pursued by an another driver, proceed to a populated area, preferably a police station. Do not go to your home and do not get out of your vehicle. Always be alert for the unexpected. With all these do's and don'ts, get out there and enjoy the warm weather. See you all safely at the EFMLS show in Syracuse. Field Trip Safety SAFETY FIRST by Bill Klose EFMLS Safety Chairman Submitted for the June 2001 EFMLS News "SAFETY RULES FOR FIELD TRIPS" were expertly laid out for us decades ago in Chapter One of the "AFMS SAFETY MANUAL". As the field trip season gets underway, it behooves us all to review the 17 items listed. I have repeated these rules as written and added a few comments within or after a few in brackets. 1-- Never go on a Field Trip alone. Have some one along who can help, or summon help if necessary. <Make sure someone knows where you went and when to expect you back. Carry a cell phone to expedite communications.> 2-- Should there be children, have the child within seeing and talking distance. A child not only could get lost, but could encounter a snake, scorpion, etc., or have an accident of some sort. 3-- Do not collect directly above or underneath people where there might be danger of falling rock. 4-- Park so that all cars can get out. Do not block the roadway. 5-- Should you leave the Field Trip early, notify the person in charge. 6-- Make sure all fires are out and wet down with water or smothered with dirt completely. 7-- Break all matches in fingers before discarding, and be careful where they are thrown. 8-- Break any cigarette before discarding and then crush it on the bare ground. 9-- Do not throw rocks, and do not allow children to do so. 10-- Avoid old mine tunnels. Never go into a mine alone. Carry a flashlight and a candle. Carbon dioxide or other gasses may be present. There may even be a lack of oxygen. <Mines are also havens for snakes, scorpions, spiders, rodents and there feces, etc.. Mines also may have uncovered deep shafts and pits.> 11-- Respect property rights and signs. Obtain permission to enter property if owned by private persons or company owned. <Attend Company safety briefings and sign releases if required. Pay attention to and practice Company safety policys.> A-- Inquire if there are vicious animals in the fields. B-- Never walk <or drive RV's like 4 wheelers> on newly planted or cultivated fields without special permission. C-- Be extremely cautious in hunting near abandoned buildings. You may stumble into a deep well <or cesspool> not properly covered. D-- Refill any deep hole you dig, so people or animals might not fall in. <Do not dump dirt and other debris into streams.> 12-- Respect another's diggings. If a person has left for lunch or for any reason with the intention of returning, and has left a pick, coat, or definite marker, find another place. 13-- Leave any place in good condition. Don't leave papers, cans, etc., lying around to mar the beauty of the place, and to tell others you have been there. 14-- Close all gates you may have opened. 15-- Never eat wild berries <or anything else> unless you are absolutely sure they are safe. <Carry bottled water and do not drink from streams or wells that have not been recently tested.> 16-- Be able to recognize Poison Ivy, Poison Oak, etc. Should there be any doubt, don't touch! 17-- Always be alert for snakes, scorpions, <ticks, spiders, rodent infestations> etc. Be very cautious where you put your feet and hands. As you can see, a lot of hard gained practical experience has been incorporated into these safety rules. To these I would add the following rules. Do not over exert or stay in the direct sunlight or heat too long. Take a rest in the shade from time to time and drink plenty of fluids. Properly wear appropriate safety equipment, sunscreen, and clothing. Bring and use the appropriate well maintained and inspected tools. Don't expect others to provide tools for you. Have your vehicle in proper working order with appropriate emergency supplies and equipment. Use proper lifting and carrying techniques to bring home your finds. Do not overload your vehicle. Many of these safety rules are covered in greater detail in other chapters of the AFMS Safety Manual and on the AFMS web site. Have a safe field trip season and see you all at the EFMLS gatherings at the Syracuse Show this summer. Lapidary Safety SAFETY FIRST by Bill Klose EFMLS Safety Chairman Submitted for the September 2001 EFMLS News "LAPIDARY SAFETY" is the substance of Chapter Twelve of the AFMS "SAFETY MANUAL" and provides a good review for the indoor activities that follow a good summer of field collecting. I am going to repeat the wisdom laid out in this chapter as written, with a few of my comments in brackets where appropriate. In "Lapidary" one may be subject to many conditions, some of which are potentially harmful. Some of the agents used, are caustic or poisonous. The following safety rules, if followed, will lessen the risk of possible harm or injury. 1-- Protect your eyes when chipping or grinding rocks. "WEAR PROTECTIVE GLASSES". (Goggles and safety shields provide additional protection from caustic liquids and large flying chips and should be worn over safety glasses when the situation warrants it. What you are currently grinding may not be caustic, but what was used in the equipment previously and may still be in the water?) 2-- Run your grinding wheels no faster than the speed recommended by the Manufacture. (If you are unsure, run the wheel no faster than 2500 sfpm (surface feet per minute). Polishing and buffing wheels are operated at a speed of 3,000 to 7,000 sfpm with 4,000 sfpm a good speed for most purposes.) 3-- Do not let your wheel become water logged. Keep it running until all water has been thrown out; otherwise, it will cause a heavy spot and make your wheel out of balance. (Do not turn on cooling water until the wheel is up to speed. Out of balance wheels could cause the wheel to disintegrate upon starting. The floor in front of grinder or polishing machine should be of rough cement or a non slip rubber mat to prevent falls on the wet surface.) 4-- Keep your wheel true. It will wear longer and there will be less chance of its parting while in use. (Grinding work should be done near the center plane of the wheel and moved back and forth across the face of the wheel to produce even wear. Do not force the work and take too heavy of a cut. Wear appropriate eye, hand, and body protection when using dressing tools. Follow the manufacturers instructions for the dressing tool being used. Only the periphery or circumference of standard grinding wheels are designed for grinding-never grind on the sides of a grinding wheel. We have all done it! Insure the work rest and peripheral guard are properly installed and only adjust them when the equipment is not running.) 5-- Keep all belt pulleys and belts covered. It may save a finger. 6-- Use dop sticks whenever possible. It may save a badly cut finger. (Small pieces may also be placed in a simple jig or fixture.) 7-- A word of "warning" to those individuals who use "dry sanding" of their cabachons. Silicosis is a serious disease which is caused by the inhalation of fine silica dust. Use a dust mask or suction blower, or change to wet sanding. "Silicosis cannot be cured". (It may be prudent to wear a chemical mask if wet sanding and the cooling water is being reused and could have dangerous compounds dissolved in it from the materials that are being or have been sanded.) 8-- Be careful with your alcohol lamp. It could cause a fire. 9-- Keep all containers properly labeled. Putting polishing powders in baking powder cans, for instance, without a proper label, can be dangerous. "(Had the Linde A Powder my hired lady used, been Tin Oxide, it could have been serious. As it was, she couldn't figure out why the cake didn't raise!)". 10-- The use of Oxalic Acid, when properly used, greatly facilitates the polishing of agates. Oxalic Acid is caustic to the skin, as well as a frank poison, if accidentally ingested or inhaled. Also getting some in the eyes from the spray from the polishing wheels, may cause a burn of the cornea, resulting in impaired eyesight. When using this acid, proper precautions must be taken. A--It is advisable to apply the polish to the wheel, with a brush. (This is good practice for all polishing compounds, not just acid.) B--Wear protective glasses. (Drip proof or mist proof Goggles over the glasses provide additional protection.) C--It may be advisable, under certain circumstances, to wear protective gloves. (A rubber apron will protect clothing and underlying skin.) D--Immediately wash any contact areas of the shin, with soap and water. Medical attention may be advisable. 11-- Sulfuric Acid and Nitric Acid are sometimes mixed with polishing compounds when faceting sapphire. They are also used in the polishing of sapphire cabachons on lead laps. These acids are severe caustics and will cause severe burns if they come in contact with the skin or eyes. In using the techniques above, one must use the utmost precautions. Any contaminated areas must immediately be washed with soap and water. If any gets in the eyes, thoroughly irrigate with water, and seek medical attention. The application of a baking-soda pack is often advisable, or the sponging with a solution of baking soda in water, to the burned area. 12-- The polishing compounds we use today are, as a rule, relatively non-toxic, except to some individual(s). The use of detergents added to the polishing powders, can cause a dermatitis of the hands. This can be eliminated if the offending substance is eliminated. (The uses of masks, goggles, face shields, gloves, and rubber aprons, can also reduce the risk of dermatitis.) 13-- The use of epoxy Resins are very irritating to the skin, and severe cases of dermatitis have resulted. This can easily be prevented by not getting the hands in actual content with the resins. Acetone will remove this, if you should get some resin on the skin. 14-- The various cutting oils used in the diamond saws, are primary irritants to the skin, and will, in many individuals, produce a dermatitis. Also, the fire hazard, in the use of certain cutting oils, must be realized and proper precautions taken. 15-- (This paragraph deals with silver-soldering and should be the subject of it's own safety article). 16-- Do not overload outlets. If in doubt, have the circuits checked by an electrician. 17-- Keep switches and motors in a dry place, where the water from grinding will not splash on them. (The shut off switch or plug should be within reach of the operator. Stand to the side of a grinding machine when starting up and allow at least one minute of warm up time before starting to grind.) 18-- Be sure to have all motors and outlets grounded. In case of faulty wiring or short circuit, the ground will absorb the shock-"not you". Standing on a rubber mat will give some protection. Electric shocks can cause death! (Circuit Breakers or Ground Fault (GFI) Circuit Breakers are highly recommended over plug fuses. A wet rubber mat will only give you a false sense of security. Water is an electrical conductor!) 19-- Suspicious wires lying on the floor or ground, should be avoided--at home or on field trips. They may be harmless, but if they are not, "beware". 20-- When a person suffers electric shock, it is important to use a stick or other object to separate him from the source before beginning resuscitation. (Shutting off the power source, if known, will also decrease the hazard to all concerned.) 21-- AN ELECTRICIAN'S FEE IS A SMALL PRICE FOR ONE'S OWN SAFETY! Too all this I would also add, use proper lifting techniques when hauling all that "good stuff" into the lapidary. It has been suggested at EFMLS annual meetings, that hazardous minerals would be a good topic. After investigating the potential topic I have come to the conclusion we should treat all minerals with respect and protect ourselves accordingly. It is better to always practice safety around all minerals than let down our guard when a hazard is present that we may not be aware of. Do you really always know what you are licking or grinding? Fire Hazard Safety SAFETY FIRST by Bill Klose EFMLS Safety Chairman Submitted for the October 2001 EFMLS News The heat of the summer is starting to fade in most locations that rock hounds like to frequent, but that same heat has left dry conditions behind. Take heed of the hazards of the fall forest and grass fire season as you pursue the last collecting days of the year. Chapter Eight of the AFMS "SAFETY MANUAL" deals with "Fire Hazard" and will be repeated here with a few of my comments in brackets where appropriate. At the approach of summer (and fall and early winter) camping season, all campers should be reminded about the use of fire on the timber and range lands. Most forest fires and range fires, are caused by carelessness; a few are caused by lightening, and some can be caused by glass contains, containing clear liquids, and bright bent cans acting as a magnifying glass, or magnifying mirror--focusing the sun's rays on combustible material. (Northern Forest Fire Laboratory, Missoula, Montana). Always build fires in prescribed areas if present, and if not, clear an area of leaves, grass, and branches, and make a protective rock ring around the fire area. (Check the local papers, radio stations, and fire rangers or stations where you are camping to see if an outside burning ban is in effect before starting a camp fire. In very dry conditions, even the underground roots may present a fire hazard, which will allow a campfire to spread. A number of recent forest and brush fires in the Northeastern U. S. have been started by campfires and trash fires spreading into the dry roots in the ground under them and then to the surrounding woods. Do not start a fire in an old strip coal mine where the coal vein may be exposed just under the surface or the old pit has been used as a land fill full of combustibles. Several very serious underground coal mine fires have been started this way.) Never leave a fire burning! Put it out! Use water if possible, then cover with earth. Never throw away a burning match until it is completely out and cold. If you smoke, be sure the "butt" is out before throwing it away. Always grind it into the earth, to make sure. (For filter tips, break down the paper and tobacco end and grind it into the earth and take the filter tip with you in your trash bag.) Remember--glass containers containing clear liquids, and cans in the open, can act as a magnifying glass or mirror, and if in the sun, can start fires by focusing the sun's rays, on pine needles, punky wood, or range grass. Keep a clean camp! Help eliminate litter, Please, and Help Prevent Forest Fires! The California agency says investigations have identified auto exhaust catalytic converters as the cause of grass fires in six locations. According to a fire prevention engineer on the Division Staff, the converters emit gasses at about 725 degrees Fahrenheit - some 275 degrees hotter than those (that used to come) from conventional auto exhaust systems. Dry grass ignites at 525 degrees under summer conditions; accordingly drivers of late model cars and trucks should be wary when they drive through grassy fields-- and doubly so, when stopped, with their engines running. (Boulder Gazette via AFMS Newsletter.) (If you should cause a fire or find one spreading, call for help spread the word to others in the area and then attempt to prevent it's spread. If it has spread over too wide an area or can not be contained, evacuate the area and let the professionals handle the fire. Do not become cut off and isolated where the fire, and or smoke, can overcome you.) With all this in mind, have a great, safe fall and early winter collecting season, free from fires. Cold Weather Safety SAFETY FIRST by Bill Klose EFMLS Safety Chairman Submitted for the November 2001 EFMLS News SAFETY FIRST by Bill Klose, EFMLS Safety Chairperson By the end of November, most areas will have had their first frost and "Indian Summer" and maybe even their first snow storm of the season, but the undaunted rockhound will continue to venture out until the ground is frozen or snow covered. Chapter 16 of the "American Federation of Mineralogical Societies SAFETY MANUAL" deals with two of winters knockout punches, frost bite and hypothermia and will be repeated here with a few of my comments in brackets where appropriate. FROST BITE "Frost bit" is a condition characterized by the (cutting off of circulation to and possible) destruction of superficial tissues, resulting from exposure to cold-- especially moist cold (Especially in the extremities, such as hands, feet, ears, nose, and other exposed areas of the body). (The Wind (wind chill factor) can add to the effects of cold temperatures, even when above freezing.) (Symptoms of frost bite begin as a prickly feeling on exposed areas of the skin followed by numbness and waxy looking patches.) Blanching or redness (erthema) of the affected area is prominent initially. Later, edema and superficial blisters develop and may brake down and form superficial ulcers (and the skin dies and falls off) or gangrene. Severe pain is associated with this condition. "TREATMENT": Prevention is more important by keeping warm and avoiding undue exposure to cold without adequate protection. (The best protection is to keep warm, keep moving, and keep dry. Dress in loose layers of warm, waterproof clothing, that cover exposed areas. Warm gloves and a hat are essential. Up to 80% of the bodies warmth can be lost through an uncovered head.) "ACTIVE TREATMENT": The affected parts are to be well dried and wrapped in protective cloth or cotton, (or tuck the hands into the armpits) and allowed to gradually come up to normal or room temperature. Application of heat or direct cold is contraindicated. (Do not rub or apply snow to the frost-bitten area. The affected area can be placed in water a little above body temperature (not above 104 degrees F). Do not place hands under running water, as there will not be any feeling initially, so they could become burned. As the frost-bitten area "thaws" it is normal to feel pain or a burning sensation.) If blister formation results (do not break them), or frost bite is severe, medical attention should be sought. HYPOTHERMIA "MOUNTAIN SICKNESS": Exposure to cold is the precipitating factor. The main contributory factors may be contact with wetness or inadequate clothing. Predisposing factors may be alcoholism, or an underlying vascular or systemic disease (such as Diabetes or poor circulation. People taking beta blockers to lower blood pressure are especially at risk). The young and the old are especially vulnerable. "SYMPTOMS" (The symptoms are initially uncontrollable shivering with pale and numb skin) Abnormal behavior, weakness, stumbling and falling, leading eventually to collapse and stupor. (Hypothermia is the loss of body temperature and can be life threatening.) (In severe cases, the person will go unconscious, and will have shallow breath and erratic heartbeat, and then the pulse weakens and slows.) "Watch your companion" on field trips! "TREATMENT": (At the first signs of hypothermia, take the victim to a warm, dry place and give them hot liquids (not alcohol).) Clear and maintain airway, if patient is unconscious. Prevent further heat loss by blankets, warm rocks, or a companion in bed with the victim. A slow return to normal temperature, is advisable. (Get medical attention as soon as possible if the symptoms have gone beyond the shivering stage.) (Do not collect alone in cold weather and carry a cell phone with you if possible for emergencies. Let someone know where you are going and when you will return. Enjoy your cold weather collecting or other activities safely.) Copyrights of the article(s) are retained by the author(s).

Safety Tips from the American Opal Society All of the following articles were written for the Opal Express, bulletin of the American Opal Society in Anaheim CA by: Cathy Gaber and Bruce Gaber Contents: Put out that Fire Scottish Two-Step Do or Die (Toxicity) Acid into Water Hot, Hot, Hot The Angle of Repose Water, water everywhere... Struck by Lightning, NOT Maybe Later Than You Think (Medication) Rock and Roll - Is Your Vehicle Ready? Hatchet Job Take it off, take it all off The Poisonous Trio Space in your suitcase flying Put out that Fire by Cathy Gaber Opal Express, Bulletin of the American Opal Society The best advice about putting out fires is to make sure they don't happen in the first place. Even in the safest circumstances though, fires ignite anyway. The next line of defense is a smoke alarm. Each home should have one on every level and each homeowner should check it monthly to make sure it is still working. Replace the batteries when Daylight Savings time changes in the spring and fall. Replace the whole alarm unit every 10 years. So, worst case scenario, you have a fire to deal with. What do you do? First, you need to know what kind of a fire it is and have the right fire extinguisher on hand. The basic principle for extinguishing a fire is actually to suffocate it, to deprive the fire of oxygen so it can no longer burn. Common substances such as water, baking soda and sand have their uses in putting out fires, but it is very important to use the right substance. For instance, never use water on an electrical fire as the water can cause the fire to spread. Baking soda is the best choice for your burning toaster (believe me, I've used it several times). On a camping trip, water may work for an out of control camp fire, but sand or even dirt will do the trick too. Another alternative is commercial fire extinguishers. They are inexpensive and, used properly, very effective. The first caveats though are to make sure that you have the right kind of extinguisher for a specific fire and to know how to work the extinguisher. It is worth sacrificing an extinguisher just for practice to make sure that everyone in the family is comfortable with its use. Commercial extinguishers also require regular maintenance (as outlined in the user's manual) to maintain their efficacy. There are four basic kinds of fires. Class A refers to fires involving wood, paper, cloth, leaves, etc. Fires involving flammable liquids, gas, oil, oil based paints and grease are Class B fires. Electrical fires are Class C, and Class D covers metals such as magnesium, potassium and sodium. No single fire extinguisher is right for all classes, though some brands work for up to three classes (A-C). You need to assess your likelihood of a potential fire based on what kind of materials you have in your home or workshop, so that you know what kind of extinguishers to buy. Classes A and C are a possibility almost anywhere, while Class B may be restricted to the kitchen, garage and workshop. An appropriate extinguisher should be placed in each room. The effective ingredient in a Class A fire extinguisher is usually water based. Compressed air expels the water. Carbon dioxide, dry chemical and aqueous film forming foam are the choices in Class B extinguishers. They work to exclude or displace oxygen and thereby "starve" the fire. Class C agents must be electrically non-conductive. Carbon dioxide is often preferred as it leaves no residue, but other dry chemicals such as compressed nitrogen can also be used. A heat absorbing, non-reactive extinguishing medium is used for Class D fires. The dry powders cover the burning metal to create a smothering effect. These class codes are listed on the extinguisher along with a number that denotes the relative amount of the extinguisher's fire fighting power. A rating of 20 means that the extinguisher can control 20 times more fire than one with a rating of one. Ask how long the extinguisher will expel the effective agent. A few seconds is probably not enough. Those with greater power generally weigh more, so you want to also make sure that you can handle the weight and still be able to control the action. Now that you have purchased the appropriate extinguishers, some thought needs to be given to their placement. They should be within easy reach, in plain view (not in a cupboard for instance), but not in the reach of children too young to properly use them. They should also be located somewhere that leaves a clear exit for the user in case the fire can not be controlled. Do not store them near a stove, heater or fireplace. If you ever need to actually use a fire extinguisher, remember the acronym PASS. 1) Pull the pin (to activate the device), 2) Aim low, toward the base of the fire, 3) Squeeze the lever to eject the extinguishing agent (some devices have a button to push instead), and 4) Sweep the extinguisher from side to side until the fire is out. Then, after you are sure the situation is under control, don't forget to replace or recharge your extinguisher. If your fire is even remotely likely to get out of control, clear people out of the area, find your escape route, and dial 911! Scottish Two-Step By Cathy Gaber Opal Express, Bulletin of the American Opal Society If your shop is a tangle of cords, And you step like the dance of the swords, Your path should be clear, So you can work without fear, Making cabs that will earn you awards. Do or Die by Cathy Gaber Opal Express, Bulletin of the American Opal Society What you do not know about a mineral can hurt you. You can not always tell by looking whether or not a mineral contains harmful elements, or if it is radioactive or if it's fumes or dust might be deadly. Most minerals are completely harmless, but with a few simple precautions you can protect yourself from those with potentially deadly effects. Elements such as lead, mercury, arsenic, uranium, antimony and cadmium are toxic. Without proper identification, you can never be sure if you might be handling some of these potentially dangerous substances. Never lick an unidentified rock, and always wash your hands after handling one. Wear gloves if there is any suspicion that a specimen may contain harmful elements. Three methods can be used to spot some hazardous minerals. Color is one indicator. If a specimen is an unnatural looking neon yellow, yellow orange or green (such as tyuyamunite, realgar, autunite and torbernite), it is probably a radioactive mineral. Radioactivity, which is found in over 200 minerals, can be easily detected with a geiger counter. Even though most fluorescent minerals are not radioactive, sometimes fluorescence can be an indicator, as the radioactive agent (such as uranium salts) can be fluorescent. Generally, only long term exposure or ingestion would cause problems, but, as the guys at the Smithsonian say, don't put them in your pockets either. Radioactivity can affect fertility in men. Unless you work extensively with quartz, crystobalite, tridymite or quartz bearing rocks like granite; asbestos minerals (amosite, chrysotile, tremolite, actinolite, anthophyllite and crocidolite); or coal, you are unlikely to be at risk for silicosis, asbestosis or black lung. The hazard from these and other minerals is in the airborne particles that get caught in the lungs or migrate to other areas of the body. Lapidaries should work in a well ventilated space, and they should be especially concerned with avoiding the fumes from working with materials like malachite, natural cinnabar and many shells. Wearing masks can help too. When working any new material, always check John Sinkankas' Gemstone and Mineral Data Book for precautions and possible toxicity. Be safe not sorry. Acid into Water By Bruce and Cathy Gaber Opal Express, Bulletin of the American Opal Society If you should ever add water to acid, Don't expect a reaction that's placid. You'll know in a flash, By the violent splash, That your project should come to a skid Hot, Hot, Hot by Cathy Gaber Opal Express, Bulletin of the American Opal Society If, in spite of your best precautions, you or your companions develop symptoms of heat related illness, these are the symptoms to watch for and the suggestions to recovery. Ample fluids are key. Heat cramps in the arms, legs or stomach, which are due to loss of electrolytes, can be caused by heavy sweating. Recommendations: replenish body fluids with water and electrolyte rich drinks; avoid salt, caffeine and alcohol which exacerbate dehydration; and rest. Heat exhaustion is caused when an insufficiency of body fluid causes the surface blood vessels to collapse while trying to expand to help cool off the body. Symptoms include weakness, anxiousness, dizziness, loss of coordination, sweating and possible loss of consciousness. Recommendations: Move to a cooler, shadier spot; lie down and elevate the feet to help restore blood volume; loosen clothing; place a wet cloth on the forehead; and drink electrolyte replacing drinks. Heat stroke, the most serious of these conditions, is caused when the body is depleted of water and salt, and body temperature rises to 103 degrees or higher. Other symptoms include a lack of sweat; hot, red, dry skin; a rapid pulse; difficulty breathing; and constricted pupils. Recommendations: call 911; cool off the victim as fast as possible by immersion in cool water, swaddling in wet cloths, dousing with cool water or by applying ice. The Angle of Repose by Cathy Gaber Opal Express, Bulletin of the American Opal Society No, the angle of repose has nothing to do with taking a nap (although sometimes a nap is a good safety precaution too!). The angle of repose is a geological term referring to the slope of earth materials at rest. We need to understand it in order to avoid landslides and avalanches. A pile of material such as sand, dirt or gravel will always have the same angle of repose as a pile of similar composition. The degree of the angle is fixed for each material. Larger, irregular or wet materials (except snow) have a steeper angle, up to about 40 degrees, while sand maintains an angle of about 25 degrees, and clay, with its even finer particles, would be at rest at even less of an angle. You can demonstrate this at home even if you don't have any sand or gravel; compare mounds of sugar and rice. You can not increase the angle and still maintain stability no matter how hard you try. Probably most of us do not have to worry too much about avalanches, but snow pack works much the same way. Dry snow has a higher angle of repose and the angle can be much higher the colder the temperature. Other factors such as centrifugal forces and wall friction also come into play, but when snow starts to melt, increasing the moisture content, the angle decreases and the snow will eventually start to move. As long as the dirt or snow is at the angle of repose, it is not a threat to our safety, but as conditions change, warmer weather, rain or disturbing the environment by walking, digging or earthquakes, the material is not likely to remain stable. Mixed sand, gravel, etc. may fall into several angles of repose depending on which particles are dominant in any strata, which makes them particularly unpredictable. Knowing how these materials may shift can help you establish a position of safety if working in this kind of environment. Just remember that the earth will do whatever it can to reestablish the angle of repose, the slope at which it feels "comfortable" and equilibrium is possible. Water, water everywhere... By Cathy Gaber Opal Express, Bulletin of the American Opal Society You've heard it, probably even said it "Water, water everywhere and nary a drop to drink". Most of the time we take clean, safe drinking water for granted and figure that we can always get bottled water if we need it, but in emergency situations at home or in the field, it doesn't hurt to have some idea of how to prepare drinking water. Never drink water directly out of a lake, stream, etc. unless you want to risk endangering your health through the ingestion of pesticides, parasites, animal waste and other pollutants. One of the most effective steps in purifying water is boiling for one full minute. Start with clean looking and clean smelling water if at all possible. If the water is cloudy, filter it first through several layers of clean cloth. Once the water is boiled, it is bacterially safe to drink and should be stored in clean noncorrosive containers. If the flatness of boiled water does not appeal to you. The water can be aerated by pouring it back and forth several times between two containers. Letting it sit for several hours or adding a very small pinch of salt may also help. Chemical treatment with chlorine or iodine can be used when boiling is unfeasible. Both work best in warm water and are not really recommended as effective for surface waters. A rough formula for using chlorine bleach is 10 drops per quart (double for cloudy water), mix and let sit 30 minutes. The water should have a slight chlorine smell. If not, repeat with half the bleach. If it smells too much like chlorine, let it sit for several hours or aerate as above. Iodine from your first aid kit can be used at the rate of 5 drops per quart (again double for cloudy water) with a 30 minute resting period. Chlorine or iodine tablets can also be purchased at sporting goods stores. Follow the package directions. Just because you are in a foreign country, do not think the same methods don't apply. An adage for travel is "Don't drink the water". This is not a joke, and the problem is not confined to drinking the water. Do not use ice in your drinks, brush your teeth, wash your food or cook anything to less than boiling unless you are sure the water is safe. You may not have access to a stove or be able to build a fire, but if you have electricity, an inexpensive immersion heater can be used. It takes patience, and you can't boil much water at a time, but it is effective. If water is only filtered, it should definitely still be boiled. The chemicals above can also be used. One of my favorite stories about traveling in India came from a very proper English school teacher. Whenever she was uncertain if the water would be safe to drink, she had an ingenious solution for brushing her teeth without using water. She used gin!

Don't stay under a tree, when it is better to flee Safe at home watching landscapes abrightening. Maybe Later Than You Think by Cathy Gaber Opal Express, Bulletin of the American Opal Society Anytime you travel or go on a field trip, don't assume you are going to return home on time. Airlines are notorious for canceled and delayed flights, but trains can also be late and cars, trucks, motorcycles and even bicycles can breakdown preventing a timely return. You do not want to be without your medications in situations like this. Factors such how far you are traveling, how reliable is the method of transportation, how remote is the destination or how likely is the weather to cause problems dictate whether having extra medications for one day or several is indicated. Even for what is expected to be a day trip, it is always prudent to take an extra dose of any medication that is taken daily, such as medicines for hypertension, heart disease or diabetes. On a longer trip take at least one extra dose more than you expect to need. If there is any chance that water will not be available for those medications which need to be taken with water, then make sure you pack water. Likewise, some medicines need to be taken with food, so you need to take appropriate food. Other medications that might be wise to include are pain killers, such as aspirin, tylenol or ibuprofen, cold medications, antacids, antibiotic cream, diarrhea medicines, and any other medicines, prescription or not, that you might typically use at home. If you are subject to anaphylactic shock, don't forget a bee sting kit, and in some areas, a snake bite kit could come in very handy. Not having many of these medications available for a day or two might not be life threatening, but others may make a big difference to your health or comfort. The small effort to pack these items will not only bring peace of mind but may possibly save your life. Rock and Roll - Is Your Vehicle Ready? by Cathy Gaber Opal Express, Bulletin of the American Opal Society You're ready for your field trip, you have your tools, safety equipment, water, etc. packed and you've made plans for what to do with the great minerals or rough you will find. Have you given any thought to getting your vehicle ready for the trip too? Nothing replaces regular maintenance as one of the best safeguards to a car or truck's continued reliable service, but before a trip, there are a number of things that should be specifically checked. Tires should be examined for bald spots and appropriate air pressure. A simple gauge that can be kept in the glove compartment is an easy way to test the latter. Car fluids should also be checked. Be sure the oil, radiator fluid, battery water and window wash fluid are at the proper levels, and don't forget gas! It might also be a wise idea to carry extra containers of all of these fluids, especially if you will be any distance from "civilization". It doesn't hurt to clean the battery contacts, and if there is any doubt about the battery's condition, replace it. To be really prepared, there are a number of useful items to pack in your vehicle. Jumper cables, a tire patch kit, a flashlight, flares, matches, a shovel and kitty litter (to be used to increase traction) are all practical things to have. A real spare tire is definitely preferable to a "toy" temporary tire which will not hold up over long distances or rough terrain. None of these things will do you any good though if you do not know how to use them. Learn to change a tire or patch one, know how to use jumper cables and how to replace your vehicle fluids. A seldom needed item, a winch, could be a real life saver if you do any off road driving especially in wet, boggy terrain. Another potential hazard to watch for especially in rough terrain is your vehicle's clearance capabilities. A low clearance family sedan, especially weighted down with a few hundred pounds of freshly collected rock, runs the danger of bottoming out, possibly damaging the suspension or puncturing the oil pan. When in doubt, don't put you or your vehicle at risk. For your own comfort, food, water and a blanket are also sensible additions. For peace of mind, you should also have your insurance provider's and roadside service's phone numbers handy. Last but not least, use your seatbelt. There is nothing worse than a field trip gone unnecessarily bad by negligent vehicle preparation. It only takes a few minutes to give your car or truck the best possible chance to carry you safely and comfortably to and from your destination. Hatchet Job by Bruce and Cathy Gaber Opal Express, Bulletin of the American Opal Society There once was a fellow named Ratchet, Who tried to break rocks with a hatchet. But don't be a fool And use the right tool. You don't want to catch it like Ratchet! Take it off, take it all off By Cathy Gaber Opal Express, Bulletin of the American Opal Society When you start working on a flat lap, a lapidary wheel, a polishing buff or a saw, you know what you plan to take off of your slab or nodule. Do you also think about what you should take off of yourself to make the project a safer one? Take off all of your jewelry. Necklaces may be obvious, but even a flat, tight ring has the potential to get snagged by the machinery. Take off any loose clothing, a tie (heaven forbid you would be wearing one in the shop in the first place!), a scarf, long open sleeves, etc. You probably can't take off your hair, but you should secure it safely out of the way. After you've taken it off, what do you want to add on? Safety glasses are always a must, an apron is highly recommended. Rubber and leather aprons give even more protection. For some tasks, gloves might even come in handy. Lastly, if you are interrupted or distracted, always take your work off the machine, not your eyes off of the work! The Poisonous Trio by Cathy Gaber Opal Express, Bulletin of the American Opal Society "Leaves of three, let them be." Can you recognize the poisonous trio - ivy, oak and sumac? You should, even if you have never been allergic. Experts at the American Academy of Dermatology report that approximately 85 percent of the population will develop an allergic reaction to poison ivy, oak or sumac if exposed to them. The active ingredient that causes the contact dermatitis is an oil called urushiol. It can remain an irritant for a year or more on clothing or tools if not washed off. Urushiol can become airborne if the plants are burned, potentially causing serious harm to eyes, throat and lungs, so mind your campfire well. Poison ivy has slightly glossy green leaves that grow in groups of three. The leaf shape may vary, and the plant may grow as a vine or as a low shrub. The plant may produce yellow-green flowers and greenish white berries that resemble a peeled orange. In winter, it can also be recognized as a hairy red vine on trees. Poison ivy can be found throughout the United States, although it is most common in the eastern and central portions. Poison oak looks similar although it is usually more shrub-like, and its leaves are shaped somewhat like oak leaves. The hairy undersides of the leaves are always a much lighter green than the surface. The plant may develop hanging clusters of greenish or creamy white berries, although many plants bear no fruit. Poison oak grows on the west coast of North America. Poison sumac grows mainly in uninhabited areas, especially in swampy locations. It grows to about 5 or 6 feet high, with 7 to 13 leaflets of elongated leaves arranged in pairs, with a single leaflet at the end of the midrib. Poison sumac can be distinguished from harmless sumacs by its drooping clusters of green berries. Harmless sumacs have red, upright berry clusters. There is no effective prevention but avoidance. Long pants, long sleeves, gloves, etc. will help protect your skin. For best results, wash contaminated skin within 5 minutes with soap and water. Remember to wash clothes and tools as soon as possible. Pet fur can carry the oil too, so if Fido went with you, he'll need a bath too. If you do get a rash, a doctor can prescribe oral antihistamines or corticosteroids and corticosteroid lotions and skin creams.

Last Revised on January 16, 2011 Safety Tips from the RMFMS All of the following articles were written by: Mel Albright AFMS Safety Chairman RMFMS Safety Chairman Contents: Electricity in shop Eye safety Snakes, bugs and varmints Rotary tools Hammering and picking Working on a slope or in a hole Sawing and burning Breathing Sunshine Fires Chemicals Lightening Equipment Convoy Electricity in shop ZAP - ZAP - YIPES by Mel Albright - RMFMS Safety Chairman You are peacefully working away in your rock shop. You reach over and touch the cabbing machine (or trim saw or rotary tool, or faceting machine, or whatever) when - ZAP - ZAP - electric shock hits. If you're lucky, you say YIPES and turn loose and unplug the appliance. If you're not lucky, the electricity surges through you down to your foot and into the ground and your spouse finds your body sometime later. Exaggeration? - Unfortunately, no. A real, common danger? - Unfortunately, yes. So, what should you do? - Several things. First and most important is to check ALL the wiring on ALL your machinery ALL the way from the plug to the other end. AND DO IT OFTEN. Frayed? Replace it. Loose? Tighten it. Cracked so water can enter? Replace it. Badly bent where it goes through or under? Replace it. And, if you get a "tingle" from the tool body itself - DO NOT USE IT until it's repaired or replaced. Second, you should make sure that you are on an insulated surface while you are working. A rubber or vinyl mat. A wooden bench - not metal. A wooden stool, not metal. A wooden floor - ALWAYS kept dry. ANY other floor - ALWAYS kept dry. So, if you touch a short, you'll get a tingle, not a zap. Third, make sure you have a grounded system and that you are using it. Modern wiring must have three wires - two carrying electricity and a grounding prong. If you don't have that, you can be in danger. If you are using an adapter to bypass the grounding prong, you can be in danger. Re-wire and ground the tool. Finally, and best of all, install a ground fault interrupter on your system. These may either be placed on the circuits in your main breaker box by an electrician or either you or an electrician can replace the plug receptacle in the wall with one - and they are NOT very expensive. What these do is turn off the electricity a fraction of a second after a short occurs - so, if you're in the short circuit, it acts before you are shocked - and saves your life or a bad burn. Most important - NOW is the time to think about this - not after you're shocked (or killed). Eye safety TAP - TAP - TAP by Mel Albright - RMFMS Safety Chairman You're walking down the street. Tap, tap, tap - you test ahead with your cane to "see" what obstacles there might be. You can't see because you were careless for a milli-second while working with your hobby. Sound like fun? Of course not - but it happens every year - to people just like you. Just a short spell of carelessness or one shortcut or one chance and it's all over. Just like that. Where in our hobby might we be in danger of having something hurt our eyes? With tools - hand or power or with chemical liquids or with glues. What tools? How? Well, start with the simplest - a rock pick or hammer. A blow from one on a rock can propel rock fragments into your eyes at a very high speed. A chisel can come out of a crack when hit and fly towards your eyes. Always use eye protection when hitting anything with anything. Any rotary tool can throw whatever touches it away at high speed. We've all had cabbing machines "grab" a cab and throw it out. A good machine is shielded and turns away from you as you use it. But, even then, things can be thrown outward and upward towards you - and your eyes. A rotary tool is being used - you "catch" on an edge - the tool and your hand are thrown up towards your face. You are leaning over close to watch your progress. That's all. Or, the rotary tool becomes fatigued and the shaft parts. The wheel and the broken shaft fly off. Towards your eyes? When it happened to me, the little rubber wheel dented the wall as if I had taken a hammer and hit the wall with all my might - but the broken shaft cut my hand first. Liquids can splatter when mixed, when hit, or when heated - and many of them will seriously damage your eyes. There is a reminder for acid and water - AAA - ALWAYS ADD ACID to water. If you add water to acid, the heat of reaction of the mixing heats the water to steam and it explodes and throws acid all over - not mildly, but with great force - even a little bit of water. Flux hidden under a piece of metal while soldering can turn to steam and throw the metal out a great speed - or - as every silversmith knows - simply splutter and pop as it warms throwing particles out as it does. Cleaning fluids - lye, acetone, gasoline(yes, really), solvents, etc. can splash and ruin an eye. Some glues have very dangerous chemicals included - one very common one and most dangerous for your eyes is epoxy hardener - get some on your hand, rub your eye, that's all it takes. Others also can cause eye damage, so make sure you keep your hands away from your eyes while working with glues. Protection? Visors offer a little, safety glasses offer a lot (WalMart sells them), face shields offer a whole lot (WalMart again). Your every-day glasses offer almost none although your dealer will call them safety glasses. Get some and USE THEM EVERY TIME - WITHOUT EXCEPTION. No job is too short for an accident not to happen. Snakes, bugs and varmints RATTLE - RATTLE by Mel Albright - RMFMS Safety Chairman When we are out on field trips, we should remember that we are not alone. We are visiting the home of a great number of other critters - some of whom - snakes, bugs, and varmints - are not real friendly. They even attack to protect themselves and their homes or because they are ill. Rattlesnakes are everyones big worry, of course. With some reason, too. Their bite can be very dangerous. And, contrary to myth, they don't always rattle to warn you before they bite. Of course, there are other poisonous snakes too - the copperhead, the cottonmouth water moccasin, the coral snake. And a whole bunch of harmless ones, too. The only way out from meeting one of these snakes too closely is to not get where they are. When you are where they might be, you must ALWAYS 'look before you leap'. Before you take a step, look ahead. Before you step over a rock (or branch, or trunk, or whatever), look on the other side to see who's lying there. Before you stick your hand in a hole or behind a rock, poke around with a stick to see if it is occupied. Always go slow, so you won't "run" into a snake. And - if bitten, go immediately to a hospital. ALL the old first aid we heard about as kids is NO LONGER RECOMMENDED! Scorpions are another danger. These range from as dangerous as a bumble bee to deadly as you go from the oak woods to the dessert. Remember, these are shy creatures. They like to hide in cracks, crevices, under rocks, under brush, in brick pile holes, in concrete blocks, in your unattended shoes, in unattended gloves, in bedrolls, or under picnic baskets - almost anywhere. So, if you stick your hands or feet into hiding places without looking first, you may get stung. Another thing, never assume a place is too small for one - they can squeeze into and through unbelievably small cracks. So - LOOK FIRST - then reach - even if you have spotted an egg size facet grade ruby. Again, if stung, it's hospital time. Ticks, mosquitoes, flies, 'can't see-ums', chiggers and other bugs are, for the most part, irritating nuisances. They can be avoided through proper use of bug repellants and flowers of sulfur. And should be. Tick bites should be closely watched after the tick is removed. If they don't clear up immediately, check with your doctor - they may have been carrying Lyme's disease - potentially fatal if not treated. Finally, if you see an animal - skunk, fox, squirrel, rabbit, whatever - that isn't acting naturally, then RUN the other way. One symptom of rabies is for animals to become unafraid of predators - including you. Another is for them to change normal habits- like nocturnal animals wandering around during the day. Don't make friends, feed, or approach wild animals. Avoid them. Rotary tools HUMM - HUMM - JERK by Mel Albright - RMFMS Safety Chairman In rock hounding, our world is full of machines that go round and round - cabbing machines, rotary tools, faceting machines, saws, grinders, vacuum pumps, buffing wheels, and more. In addition to going round and round, many of these machines have belts and pulleys attached that also go round. Every one is trying to tear off your finger - if you'll just be careless enough. Or grab your shirt (or blouse) and pull you into the works so you are nose-to-nose with a saw blade or grinding wheel or whatever. Or grab a sleeve and pull your arm into a pretzel. Or grab other things and do unpleasant things to them. Naturally, none of these things will ever happen to you since you are lucky. But the rest of us need to learn how to develop ways of working that prevent such happenings. First, and most commonly ignored, NEVER wear a ring while working with rotary equipment. Any snag that develops may grab a ring and jerk. And a ring is very firmly attached to your finger. So a ring is a very dangerous thing. If you don't believe this, try putting rough material into a buffer and feel, hear, and watch the violent action when the buffer 'grabs' the object. But wear a face shield if you try this - it's not worth losing an eye over. Second, never work around rotary equipment with long sleeves on. They can catch on the rotary part (or under a belt on a V drive), wind up your sleeve and pull your arm into the machinery. Multiple compound bone breaks may be the worst you get from a small motor. A lost arm may result with a larger motor. Third, never wear loose, baggy clothes - especially shirt or blouse - that puff out where they may be caught in the machinery. Again, they can pull you into the machinery - and often it is your face that reaches the machinery first - and the unpleasant possibilities are obvious. Finally, the hazards of wearing gloves of any kind are also obvious. Creating beautiful things with power tools is fun and absorbing. Getting caught can not be pleasant. Dress right and be safe. Hammering and picking BANG - BANG - WHIZZ by Mel Albright - RMFMS Safety Chairman Hammers and picks and axes are an important part of our hobby. We use them to explore, to check out a rock, to powder rocks, to form silver, to chisel loose samples, to make arrowheads, to cut firewood, and for a lot of other things. Yet, these simple tools can be very dangerous on occasion. The most obvious and most common danger is simply to hit ourselves with them instead of a rock or log or chisel or metal piece or nugget. Why in the world does this happen? Not because we are all klutzes in fact, almost never. Most often, it is because something moves too soon or as it is hit. Your feet shift because you are off balance when you swing the tool. Your holding hand moves because you didn't have a firm grip on what you are swinging at. Your attention is distracted as you swing (Suzie hollers 'Mommie'.). Or, your tool doesn't hit squarely and slides off into your finger, or leg, or foot. So the obvious ways not to hit your finger or your leg, or your foot is to be sure you are balanced, to make sure the item to be hit cannot move before or as it is hit, and, if at all possible, not to have fingers, legs, feet, or any other part of you where the tool will hit it if something does go wrong. Another danger from hitting things is that the tool may bounce back into your face. The force you apply must go somewhere and some part of it returns to the tool so that it bounces. If your face happens to be in the way when it does, teeth or eyes may suffer - or bones. So, when swinging such a tool, another safety practice is to make your swing so that any recoil will push the tool sideways away from you. An obvious danger from the use of these simple tools is that chips may fly - of rocks, or wood, or pieces of metal. If you study the physics involved in hitting something, you will find that the forces may direct the chip at high speed BACK IN THE DIRECTION FROM WHICH THE BLOW CAME. Again, if your eyes are in the way, you have a bad problem. Finally, remember that what you hit may flip out from the force of the blow if you don't hit it dead center. While this most often results in a high speed missile sideways, it can also flip UP (as in tiddley winks) and hit you. So, place the object so if it does flip, it will go away from you and so that if it flips up, it'll go over your shoulder. All simple ideas? Yes. All important? You Bet. Holes and banks SLIP - SLIDE by Mel Albright - RMFMS Safety Chairman Did you ever hear about the "angle of repose"? No, it's not how you stretch out when you want to rest or sleep. It is an important factor in the design of earth or rock structures - and what keeps you safe or puts you in danger when you are on a field trip. Simply, the term means that, for each material - rock or sand or earth or grain or any other mixture of particles - there is a slope, or angle, at which material starts sliding down a bank. If the pile is at a lower angle, the bank is stable. If the pile is at a higher angle, the bank is unstable - and may start sliding at any time. You've seen this effect in digging a hole. Stuff slides back in even as you are trying to dig it out. It is important to note that the slope may not slide until some outside force triggers it - witness avalanches and landslides. So, whenever you are digging in a hole, or exploring a bank, or exploring a quarry or mine, or a rock pile or a tailings dump, you are counting on the angle of repose to keep you safe and not allow you to be suddenly buried under a bunch of dirt or rocks. And the angle of repose is not constant. Wet material may slide much easier than dry. So what was safe before the rain is unsafe after the rain. Remember, too,that ALL tailings and other mine dumps are at their angle of repose because of the way they were made. The unfortunate part is that you cannot know whether the material around you is at it's angle of repose or above it. So, you cannot know if you are safe or whether a blow from your shovel will trigger a slide or someone walking above you or what. And, almost every day we read or hear about someone dying because of the failure of a bank - in mines, in quarries, children digging caves, rockhounds hunting rocks, workmen digging ditches. So how do you work safely? Well, if you are digging, always dig a hole - NOT a cave (even a little one). And, although it's far more work, dig the hole with gradually sloping sides. And, if on a rock pile or tailings dump, be sure there's no one above you who might start a slide. And, if around a bank, test it a little with a hard blow or two or a "stomp", and, again, be sure there's no one working above you. And, in every case, wear a safety helmet - the proverbial 'hard hat'. WalMart carries them - and they are not expensive. Sawing and burning BUZZZZZ by Mel Albright - RMFMS Safety Chairman Rock Saws are wonderful gadgets. You put a rock in, clamp it, turn on the saw, walk off and do something else, and later, when you think of it, you go out and start over on the next slab slice. Simple isn't it? Ain't life grand? All mod. con. However, with all this convenience comes some safety problems and some economic worries. Both lie in the rock clamp and the feeding mechanism. Simply put, things can go wrong when least expected. The biggest worry comes because rocks sometimes work loose from the clamp, turn sideways and seize the saw blade. On most rock saws, this stops the blade, but not the motor. So, the motor pulley keeps turning while the drive belt does not. This generates heat which can and has started fires - first the belt, then the saw oil, then the garage. It happened to a friend of mine. Luckily, the house was saved. To prevent such a problem from hitting you, always stay where you can hear the saw so that you'll immediately know if something goes wrong. My friend has a good solution with his new saw in his new garage. He bought two cheaply kids walky-talkies - tapes the transmitter open on one and sets it by the saw - keeps the other near himself inside so he can always hear the saw. No worries, now. The economic problems arise when the saw is not started into the rock properly or when the rock shifts slightly while being sawed. Many drive mechanisms exert considerable force on the saw. When the blade tries to cut a side-ways circular path, the drive keeps pushing and you end up with a blade shaped like a dish - and the opportunity to buy a new one. Eventually, the blade will seize and the fire problem will appear, but by then it's too late to save the blade. Solution? I start the saw into a cut by hand pushing the rock into the saw and then pulling it off. I repeat this until I can see the saw blade does not deflect sideways when the saw first meets the rock. Then I engage the drive mechanism and let the automatic system complete the cut. Messy, but far less a problem than buying new blades - and maybe having a fire. Sometimes, you get a rock that just will not stay in the vise - often, it's Brazilian agate teardrop shaped. The solution is to enclose the rock in plaster of paris in a square mold and then clamping the cast into the saw. This also avoids the problems mentioned above. Breathing GASP - GASP by Mel Albright - RMFMS Safety Chairman All of us enjoy breathing. Some of us know it's not always easy - allergies, hay fever, asthma, emphysema, or loss of a lung can interfere. Yet many of us in the rockhound hobby blythly ignore the fact that we often work with materials that are dangerous to breathe or damaging to our lungs or, sometimes, fatal. What are these materials? Fumes from heating or burning are one source. Burning off flux, heating cleaners, burning glues or paints, heating minerals, burning off wax - these can all produce fumes that are potentially harmful. Any heating or burning should be done in a well ventilated place, in a protective ventilator hood or outdoors. The airflow should move from you to your working area to outdoors or some other safe area. A kitchen stove hood with side walls from the hood to the workbench works great. Fumes from chemicals are another source. Glues (household, epoxy, etc.), paints, solvents (acetone, benzene, toluene, terps, odorless solvents), thinners, oxidizers, bleaches, acids (hydrochloric, sulfuric, nitric, fluoric) and other material we use all release possibly dangerous materials into the air. In fact, we often identify these things by smell. Some of these things - like benzene - cause problems only if used often over a long period of time. Others - like hydrogen fluoride (fluoric acid) - cause bad problems instantly. Again - ventilation is the solution. Dusts from rocks can also be dangerous. They can cause silicosis (or pneumonoultramicripicsilicovolcanocobiosis*) such as from too much agate dust over too long a period. They can be poison such as dust from malachite. Anything we do that is done dry can and does produce dust - especially grinding. Again ventilation is a solution provided you cannot use water or oil to prevent dust release. Or wear a good dust mask - WalMart available. Remember - you get the fresh air first, then it moves to your work, then it goes outside or somewhere else safe. EVERY time. * Look it up. Sunshine SSSS - SIZZLE by Mel Albright - RMFMS Safety Chairman Sunshine is shining. Rockhounds are hunting. And unprotected skin is turning red and burning. In 10 or 15 or 20 years, someone - maybe you - will be saying, "Why oh why didn't I listen to people back then. I don't want skin cancer. No!" Skin cancer is the fastest growing form of cancer these days. And most of it harks back to when it was considered stylish and good looking to have a good tan. In our youth, many of us managed to get awesome burns. And now we hear that just one bad burn as a child doubles our chance of skin cancer later in life! What to do? Wear suitable clothing - hats, dense cloth shirts and pants, no shorts. Apply protective sun screen to ALL exposed areas when you are going to be outdoors. If possible, stay indoors or in the shade during the time of greatest danger - 9 AM to 5 PM under daylight savings time. What is a suitable sunscreen? It is one labeled with a protective factor of 15 or more. The number refers to a degree of protection - with a 15 factor, you can stay out 15 times as long as usual before you get a sunburn. NOTICE - it delays - not prevents. So if you normally sunburn in 20 minutes (yes, light skinned people do), then with a SPF 15 applied, you can stay out 300 minutes (5 hours) before you are sunburned. Best are waterproof, non-allergenic sprays, creams or lotions. Are you already in trouble? Do you have an irregularly shaped or varied colored mole anywhere on your body? Or one which is changing shape or size? Is it 5 mm or more? You may have deadly, fast spreading melanoma. If so, you'd better have it checked - REAL SOON. Odds of this are 1 in 105 and 22 percent will die. Do you have rough patches on your skin? Little dry white clumps? Or dry patches? Then you might have actinic keratomas which can evolve into cancer. Easily treated. Again, get checked - SOON. Basal cell cancers are small fleshy bumps or nodules. 400,000 people a year get these. If untreated, they will bleed and crust over again and again. Squamous cell cancers start as nodules or red, scaly patches. 100,000 people a year get these and 2200 die. Obviously, this stuff isn't for fooling around about. Take action, NOW! Fire Hello - 911? by Mel Albright - RMFMS Safety Chairman Have you ever considered rockhounding as a fire hazard? Do you ignore the possibility? Do you have 911 memorized? Some spare skin stored up? A wig to replace your natural hair? Well, maybe we should all slow down and consider what all we have around that might catch fire and burn. Rocks? Well, no - unless you have some Colorado oil shale. But oils and solvents and glues? You bet they will. If I look around my shop, I find acetone (for cleaning off facet material, for releasing epoxy, for releasing super glue), kerosene, refractive index oil, saw oil, machine oil, super glue, epoxy paint and glue, household cement (one of the most dangerous), alcohol, and, occasionally, commercial solvents for various purposes. And the proverbial oily rags. And a wastebasket I haven't emptied for several years. Every one of these will burn. And I bet you have some I don't have. Some will ignite extremely easily acetone and alcohol for example. And my shop is indoors. Shame on me - not one solvent is in a safety container. Not one glue is in a fireproof box. And I seldom worry about ventilation when I use these things. I've been lucky - not careful. They tell us it takes three things to have a fire - heat, fuel, and oxygen. As I have shown, most all of us have the fuel. The oxygen is in the air all around us. The only thing needed to start a fire is heat - from a torch - from a soldering iron - from an alcohol lamp - from a sparking brush on a motor - from smoking from a spark when using a tool (remember flint and steel fire-starter kits?). Solutions? Keep all solvents outdoors in a safe location. Bring in only small quantities, in a safety container, and have them in only for the time you need them. Place glues and the like in a metal box with a lid. Remove oily rags and other combustible materials and discard them. Practice good housekeeping. Be aware of fire danger and avoid it at all times. And, MOST IMPORTANT, keep a Class A,B,C fire extinguisher in your shop. The A,B,C ratings mean that it is good for any fire - paper/wood, electrical, or solvent. Be sure you know how to use it. It's hard to read the instructions while a fire is burning in your shop. Chemicals BOIL AND BUBBLE, TOIL AND TROUBLE by Mel Albright - RMFMS Safety Chairman Have your ever thought that most of us own a chemical laboratory? That we work often with hazardous chemicals? That we'd probably be in trouble if OSHA and EPA could see what we are doing? First, let me say, as a Chemical Engineer and a life-long Research and Development worker, that a good deal of OSHA and EPA warning and rules and the like about chemicals are far, far overblown. BUT, some are not. AND, if you're not an expert, you probably can't tell the difference. If you wonder why I say that things are overblown, just consider that vinegar odor is listed as being of the same class of hazard as fumes from hydrochloric acid. A lump of lead on the table poses no danger to you while a lead salt in solution in something you eat or drink can be dangerous. Other examples abound. Why say all this? Because, you SHOULD ALWAYS use common sense when working with any chemical but you SHOULD NOT be so frightened by the government that you are afraid of chemicals. After all, salt, baking soda, vinegar, your medicine, cough syrup, detergents, cleaners, lye, bleach, and many, many other common household items ARE chemicals. So, having said all that, I'll cover the most important items about working with chemicals. First - READ THE LABEL AND ANY ATTACHED LITERATURE!!! All the really dangerous chemicals are required to have safety information with them. If you aren't sure, write the manufacturer and ask for the safety sheet on the chemical. They're required by law to send it to you. Second - USE COMMON SENSE. Don't ask for troubles you don't need to have. If it smells, use in a ventilated area or outdoors. Don't get things on your skin if there's no reason to do so - wear gloves. If it'll splash, protect your eyes.Take care not to spread things around. Getting something on your hand might be safe, but it might be very dangerous to then rub your eyes with your hand. If you are going to boil or burnout or apply a torch or otherwise heat a chemical - DO NOT BREATH THE FUMES. EVER!! ALWAYS ventilate to the outdoors. Third - DON'T MIX CHEMICALS. Some chemicals are safe by themselves, but react to form dangerous products when mixed. The classic example is household bleach and bowl cleaner - they react to form chlorine gas which can burn your eyes, nose, throat and lungs - permanently. Clean up one thing before starting with the next. Fourth - STORE CHEMICALS PROPERLY. Keep unused chemicals tightly sealed in their original storage container. If they offer any fire hazard, keep them outside, away from wooden structures. Fifth - Remember AAA - ALWAYS ADD ACID to water to dilute it or clean it up. There's a high heat of solution and, if you do it the other way, the water will be heated and form steam and then 'blow up' and blow acid all over the place AND YOU. What chemicals do rockhounds use? A bunch. Too many to list. They include acids, bases, glues, oxidizers, reducers, fluxes, solvents, pickles, cleaners, and more. Don't be afraid to use them. Do use them safely and properly. Then you'll have no problems. And, never, never hurry. Think about it before you start. Lightening RUMBLE, RUMBLE - ZAP - BANG by Mel Albright - RMFMS Safety Chairman It's a wonderful day. We have gone on a field trip. We're out there, well away from the car when, rumble, rumble. We look around. There's a big black thunderstorm bearing down on us. It has lots of lightening. And the lightening is hitting the ground. Panic time? No. Action time? Yes. Don't panic, but do know what to do. First, let's talk about an imminent lightening strike. I've been near 3 in my life. Your hair stands on end. Nearby wiring or fencing has sparks flying around. A sizzling/frying sound can be heard. Then Zap, the lightening hits. Then you hear it. Then you smell the ozone it created. Then you start shaking. All in a few seconds. But you do have time to protect yourself somewhat. On your knees, IMMEDIATELY. Grab your ankles and bend over as low as you can get - you do NOT want to be the tallest thing around. Do NOT lie flat on the ground. If you have a little more time and a little more warning, you can do much better. First choice - take shelter inside a building or car and stay away from wiring and plumbing. Contrary to rumors - the new tires do NOT conduct electricity. Second choice - don't take shelter outdoors under anything - tree, tent, whatever. Put down anything you are holding that might conduct electricity (like a golf club, geologists pick, etc.). Avoid fences, tracks, machinery, poles, power or phone lines and water. If you are in a body of water, get out fast. If you are in a boat, head for shore and get out, fast. If you are in a group of people, spread way out. If you have a plastic or rubber sheet or raincoat, put it under you. It's much better to get wet. Thunderstorms can be beautiful and exciting and welcome, but don't forget - they're dangerous, too. Equipment RAH-RAH, THE COMPLEATE ROCKHOUND by Mel Albright - RMFMS Safety Chairman Are you the type of rockhound that has everything you need for your hobby? Do you consider your equipment complete. Are you all decked out with all the gadgets you need? May I suggest another group you may not have? Safety equipment. It's all available at WalMart, at your local hardware store, at the pesticide store, at local stores specializing in safety. Most are inexpensive. All are inexpensive compared to the injuries, losses and deaths they may prevent. A few: Hearing protectors. These vary from foam plugs for your ears to special plugs that allow you to hear speech to earmuff types like you've seen baggage handlers wear at the airport to super-duper ones that are electronic and cancel out undesirable sound waves. Masks. There are a great variety of types. The simplest are simple dust masks - with or without eye covering. Then there are solvent masks for use when around solvents. And chemical masks for use when around undesirable chemicals and in spraying pesticides. And special masks for special things - asbestos, carbon monoxide, chlorine, etc. And the most sophisticated which either supply air with them or have tubes leading out of the dangerous zone to an air supply. Shoes.There are safety shoes. They have a steel cap in the toe which protects your feet from heavy objects hitting them. There are rubber boots to protect you from water and dangerous sludges (or fresh cement). There are hiking boots especially designed to support your ankles in rough terrain. Fire Extinguishers. There are three general types - no matter what chemicals are inside them. One (Class A) is for use only on fires such as paper and wood. One (Class B) is for use on electrical fires. One (Class C) is for use on solvent type fires. Some fillers are safe for use on more than one class of fire - and will be labeled for more than one class. Best of all is a Class A,B,C extinguisher which is good for any fire. They come in several sizes. Little ones are cheap, but often run out too soon. Get a larger one. Gloves. Gloves do more than stop blisters. They also protect the hands. Best for hand labor are leather type ones such as the horsehide ones found in farm and garden stores. The other type is plastic or rubber which will protect the hands from solvents, acids and or hazardous materials. Eye and Face shields. These come from the simple safety goggle (which will go over your glasses, if needed.), to safety glasses (NO, your "safety" glasses from the optometrist do NOT qualify - industrial standard safety glasses are needed.), to face shields which cover both the eyes and the whole face. Aprons. Cloth aprons protect your clothing from messes. Rubber or plastic ones protect you from chemical burns and the like. Hard Hat. Approved hard hats are readily available and work wonders when something falls on your head. Cold? Wool liners are available. The compleate rockhound probably has all of these - do you? Convoy HONNNK, HONNNK by Mel Albright - RMFMS Safety Chairman "Hey, y'all, - we've got us a convoy here." We rockhounds go on lotsa field trips. Often we go in convoys. Mostly, some- one says "Follow me.", we all pile into our trucks or cars, and away we go. Sad to say, we're not really thinking about safety. So let's do that a little while. First, before you leave, everyone should get full information about where you're going and how you'll get there. Then, as the convoy goes along, no one will get frantic about losing it and missing out on the trip. That way, they'll pay attention to what's going on around them instead of worrying. A quick copy of a hand drawn map or a written directions would be best. Otherwise, talk slow so people can make notes. First, let's talk about the leader(s). The first car should contain the guide who knows exactly how to get there AND the first car should have a CB radio AND the first car should have a cruise control. The last car should also contain a guide who knows how to get there and a CB radio. That way, the last guy can tell the lead car when to slow down, to speed up, that there's a problem, or what else is happening. If someone has car trouble, the "tail-end Charlie" can also make sure they get the help they need and get on to the field trip if they want to. The speed of the convoy is important. Ever watch a kid pull a Slinky across the rug while holding one end? The coils close up and spread out at random. The back end is standing still one minute and then moving way faster then the front end the next. Well - that's what happens in a convoy. If all the cars went real slow, this stretching and shrinking might not be too bad. If they went real fast, things might get out of hand. And, there's always road conditions, traffic lights, stop signs, and other traffic to worry about. So, the first car should adjust speed according to what's going on. On a 4-lane, speed up (see below). On a dusty road with no wind blowing, slow way down. After a stop sign or after a traffic light or after a turn, slow way down until "tail-end Charlie" reports being by the point of change. On the open road, set the cruise control at 5 to 10 miles per hour under the speed limit. Then the stretching and shrinking won't get out of hand and no one will worry about getting left behind and the last car won't have to drive 80 once in a while. If you're driving in the convoy, there are some things to pay attention to, also - like the plate number and color of the car you should be behind. Your distance behind the car in front should be as constant as you can make it. For safety reasons, you should observe the 2-second rule - never be closer than 2 seconds behind (count "one thousand one, one thousand two"). If you see a car behind that isn't in the convoy and wants to pass, open up your spacing so they won't feel that they have to pass several cars at once. That way, they probably won't tail-gate you, either. Do you remember the old saying "Monkey see, monkey do"? That should be you in a convoy. If the car leading you shows brake lights, step on your brakes. If it shows a turn signal, turn on your signal. If it changes lanes, you change lanes. If it speeds up or slows down, you do the same. If it pulls to the shoulder, you do too. And if you have a CB, great - tune in on the conversation, but don't join in unless there's a real emergency. And when you all get there with no problems, smile and start hunting that find of a lifetime. Copyrights of the article(s) are retained by the author(s).
