Suggested Activities: 18.3A Survival Report: Have the students complete a survival report. 18.3B Construct a Temporary Shelter: Take students outside and have them construct a temporary structure using materials from the school grounds (you may wish to “import” a few items). 18.3C Water Can Demonstration 18.3D Make Your Own Survival Kit Teaching Outline I. Self Reliance is survival A. Know human limitations B. Know your own level of competence C. Know your own comfort zone D. Know how to handle an emergency situation when it arises E. The philosophy of the survivalist 1. Nature's Priority: take care of the brain first and it will take care of you a. Survival is a 80% mental, 10% equipment, 10% skills b. Give the brain mental rest 2. Wilderness native a. Adapt to the situation and environment b. Hand to mouth level: comfort takes second seat c. You may die of exposure if you neglect yourself but you may also die if you baby yourself II. Anticipate the problem A. Where might a problem occur? B. Pre-plan C. Prepare for changing weather D. Inform your friends and relatives at home where you'll be E. Use Trail Register or leave note on car, check in with rangers F. Develop a knowledge of first aid 4018.14 Forestry and Natural Resources Unit 18: Outdoor Safety and Survival Skills III. Plan outdoor travel A. Plan your day: think about future needs B. Take along a survival kit: 1. Shelter 2. Fire starter 3. Container for heating fluids 4. Signaling device 5. Knife 6. Medical supplies 7. Compass 8. Extra clothing (wool shirt) IV. When an emergency occurs: being lost A. Mental factors affect survival 1. Set your goal: to get back 2. Overcome basic fears and imagination B. Signal for help 1. Contrast is the key to effective signaling (i.e. dark on light) 2. Signal area a. A clearing is best b. Make signal seen from all directions 3. Types of signals (TM p 24) a. Fire - three fires in equilateral triangle means “help!” b. Ground to Air - SOS or Letter X c. Audible - three loud noises of any kind d. Mirrors - Practice is essential in signaling e. Colorful flags (clothes) f. Arrows indicating direction of travel V. Travel A. Many survival situations do not require travel; stay put and conserve energy - build shelter, fire, signal B. If you determine to travel 1. Take everything possible to save you 2. Stay dry, stay warm 3. Stay on predetermined direction 4. Travel slowly, camp early near water and open area 5. Travel path of least resistance to conserve energy C. Caution is the watch word in survival travel 4018.15 Forestry and Natural Resources Unit 18: Outdoor Safety and Survival Skills VI. Improvising Navigational Aids A. The difference between familiar and unfamiliar is the time you take to observe, hear, and feel the area 1. Make mental map of travels 2. Note odd sites B. Establish reference points before traveling C. Nature provides directional aids 1. Vegetation grows toward the sun a. Tree foliage denser and flowers are on the south side b. Tree's growth rings are wider to the south c. Lichen grows on tree's north side in the shade 2. Natural objects - high points, peaks, valleys 3. Solar system- sun, stars, moon a. Locate north with the Big & Little Dippers at night D. Improvising a compass 1. Needle floating on smooth surface 2. Shadow stick compass 3. Watch VII. Priorities of Body Survival A. You can live for approximately 3 minutes without air; 3 hours without body shelter under extreme conditions; 3 days without water; 3 weeks without food B. You can live for approximately 3 minutes without oxygen 1. When breathing stops: a. Living cells cannot produce the energy necessary for life b. Brain cells are damaged. 2. Administer artificial respiration at once C. Clothing - exposure can kill in less than 3 hours if clothing or shelter isn’t geared to environmental conditions (TM p 25 & 26) 1. Remember "COLD": Color: Black absorbs heat, white reflects it; Overheated: ventilate, avoid overheating, perspiration wets fabrics the same as rain; Layer System: Easy on, easy off layers to help regulate body temperature; Dry: Keep all fabrics dry, wet clothing loses 90% of its insulation, wool is the only fabric that gives insulating protection even when wet 2. Wear a hat - the brain receives 20% of the body's blood supply and 25% of the oxygen intake; the unprotected head radiates a large proportion of the body's heat loss 3. Always dress for the worst weather during a given season; carry an extra wool shirt D. Shelters (TM p 27 & 28) 4018.16 Forestry and Natural Resources Unit 18: Outdoor Safety and Survival Skills 1. Emergency situations (rain, snow storms) do as local animals do - burrow in or crawl under foliage 2. Shelter must serve immediate needs of builder, providing minimum body heat loss and maximum body protection 3. Good shelter site includes: a. Protection from wind and storms b. Protection from flash floods, rocks, high tides c. Freedom of pests, poisonous plants, insects and harmful animals d. Level ground for bed and fireplaces e. Availability of materials, shelter and bed f. Source of firewood g. Food sources and drinking water 4. Types of shelters a. Windbreaks; brush; V-shaped b. Rock shelter wind breaks - above timber line rocky sea coast; U-shaped c. Lean-to - Use anything available d. Wickiup - longer to build; more permanent, more serviceable; provides protection from all sides e. Sweat Lodge - wickiup covered with thick layer of dirt; very warm shelter f. Snow caves - dug in snowbank that has a good crust (TM p 28) g. Caves and mines - Use caution in damp caverns h. Hot coal bed - heated stones adequately covered provide a warm bed E. Water: An absolute necessity for life processes; you can die in less than 3 days from dehydration. (TM p 29) 1. Plan every trip with a surplus of water and salt. 2. Plan to carry water from home in an unbreakable container rather than expect the spring or creek to be flowing. 3. Pure water is often a problem; always carry iodine or water purification tablets. 4. Always melt snow or ice before consuming to save your body from losing valuable calories; put a small amount of water in pot to facilitate the melting process. 5. Your body is 80% water; a loss of water equal to 7% of your body’s total weight can cause dehydration and will be a serious threat to all normal chemical body functions. 6. Ration your sweat, not your water; perspiration is the body’s automatic cooling system. 7. Digging for water in arid areas is often not worth the effort; often more water is lost in digging than is gained from the well or solar still. 8. In a real emergency situation, you can locate a water table close to the surface by digging: a. At low spots of green vegetation as willows salt grass cattails b. At the base of cliffs and rocks where an abnormal amount of vegetation is thriving c. In dry mudholes sinks river beds and bends of river beds d. Anywhere the ground is damp or muddy 9. Water can be obtained from the soil: a. A hole dug in damp sink areas allows water to seep in and collect 4018.17 Forestry and Natural Resources Unit 18: Outdoor Safety and Survival Skills b. Mud wrung in a shirt or other cloth will force out water c. A solar water still produces pint of water in about 3 hours 10. Water can be collected from air and plants: a. Barrel cacti b. Mopping up morning dew with cloth and wringing it into a container (you receive a quart an hour) 11. Remember: Nothing should be eaten if water is not available. Eating uses up the body's water reserve. F. Food 1. You can live for approximately three weeks without food if you have water and minimize your energy use a. Food is a great pacifier, but it is not essential in short term survival b. Stored body fuel (fat) can be converted to usable energy for weeks at a time c. Often the energy expended in collecting wild foods is greater than the energy value received once the food is found d. Wild foods are required for long term survival situations 2. Plant foods are the easiest to gather and often the most nutritious; edible plants differ greatly with plant life zones and habitats; the following basic tips can be applied in most situations: (TM p 32) a. The seeds of grasses, pine and oak trees are safe and nourishing; grind on rock metal to make flour b. Tender plant leaves and flowers are usually the best tasting; pick them early in the morning and eat fresh and raw (when the vitamin content is the highest) c. Plant roots - generally supply more food value than greens - use digging stick d. Cambium (inner bark) edible raw, fried, baked, or boiled e. Blue and black berries, red berries are usually very edible but white berries never are. f. Avoid all plants having milky sap--except dandelions g. Never eat wild mushrooms; they have practically no food value and the risk of picking poisonous ones is too great h. Needles from, pine, spruce or hemlock trees make excellent tea high in vitamin C 3. Animal Foods a. Animals are an important source of food for the long term survivalist l.) Hunt and trap only for survival purposes 2.) Methods for obtaining game are cruel, use only if no other means are present b. Methods for obtaining small fur bearing animals and game birds 1.) Rocks - poor choice 2.) Throwing stick 3.) Spears and bows and arrows 4.) Snares (TM p 30) c. Methods for obtaining fish 1.) Hooks carved from bird bones 2.) Fish traps 3.) Spears - 3 prong shaft d. Methods for obtaining reptiles (snakes, lizards, frogs) 4018.18 Forestry and Natural Resources Unit 18: Outdoor Safety and Survival Skills 1.) Long, flexible, whip type stick 2.) 3 prong shaft (same as fishing); be certain to remove the heads and skin on all reptiles before eating e. Insect foods are nourishing and easy to collect 1.) Grasshoppers, crickets, beetles; pick off grass and plants in morning when they are chilled and dormant; good roasted, served in soups or stews 2.) Ants - good roasted and ground into powder 3.) Grubs and larva - good protein; easily collected under rocks and logs 4.) Water nymphs: underside of stones and grass stems in water 5.) Remember always cook insects to remove parasites VIII. Building a fire (TM p 31) A. Important tool for survival: when controlled, provides warmth and dries clothing; required for cooking, excellent signaling device and lifts morale; uncontrolled it can destroy everything in its path B. Fire pit location and construction - Scratch down to mineral earth that is free of forest duff, grass and roots, to an area approximately 5 to 6 feet in diameter C. Finding and preparing fuel for fire 1. Fire triangle; fuel-oxygen-heat 2. The larger the wood, the higher the combustion temperature a. Tinder b. Kindling c. Sustaining fuel D. Starting a fire 1. Match 2. Flint and steel 3. Bow drill 4. Friction 5. Magnifying lens 6. Battery sparks E. Size of fire 1. Small fire: "keeps you warm by the fire" 2. Large fire: "keeps you warm running for wood" F. Putting out a fire properly 1. Soak it 2. Smother it with earth 4018.19 Forestry and Natural Resources Unit 18: Outdoor Safety and Survival Skills Laboratory Exercise 3A Water Can Demonstration Objectives: 1. Demonstrate heat loss 2. Demonstrate fabric comparisons in relation to heat loss. 3. Demonstrate the effects of wind and water on heat loss. Materials: Four 2-gallon metal cans. Thermometer. Enough wool fabric to cover 2 cans. Enough cotton fabric to cover 2 cans. Plastic bag big enough to hold 1 can. One piece of foam rubber or styro-foam big enough to form a base for 1 can. Set-up: (TM p 24) 1. Fill 4 cans with hot water, note temperature. 2. Wet 1 piece of wool, 1 cotton. Cover 1 can with each. 3. Cover 1 can with successive layers of cotton, wool, plastic. Set on insulation. 4. Leave 1 can “naked.” 5. Place all cans in shaded, windy spot outdoors. Record: 1. Initial water temperature. 2. Outside air temperature. 3. Water temperature in each can at 1-hour intervals. Put all 4 cans through a sprinkler-simulated rainstorm. Radiation, convection and conduction remove the heat rapidly and simulate their effect on the human body under similar conditions. Compare: Conclusions: Different combinations of wet vs. dry, wool vs. cotton, naked vs. protected. Heat loss is greater when wet and or windy. Wool slows heat loss more than cotton. 4018.20 Forestry and Natural Resources Unit 18: Outdoor Safety and Survival Skills Exercise 3D Make Your Own Survival Kit Survival kit should consist of the following: 1. SHELTER 2. FIRE STARTING KIT 3. CONTAINER FOR HEATING FLUIDS 4. SIGNALING DEVICE 5. CUTTING TOOL 6. MEDICAL SUPPLIES 7. COMPASS SHELTER l. A plastic, highly visible tube, 8 feet long by 40 inches flat is probably the best shelter possible. You can make one by getting two of the largest garbage can bags you can find, cut the bottoms out of them, and tape them together with good electrical tape. This gives you an inexpensive plastic tube. Now try it on - it will condense, so open it up and allow the air to move around as the humidity builds. A tube helps retrain heat. It also protects us from the wind, cold, and moisture common to the outdoors. 2. Regular l mil or 1.5 mil flat plastic sheet, 8 feet by 7 feet. 3. In desert areas - a space blanket is most helpful and protects from the sun during the day. It is a fairly good blanket at night. FIRE l. At least one hard wax plumbers candle about 4 Inches high. Two are better. 2. Wooden matches, waterproofed with a light coating of paraffin or fingernail polish. 3. A good match box container with a flint bottom is a good item. Add tinder (cotton, tissue, etc.) to your kit if desired. 4. Heat tabs are good - read cautions about toxic gases. 5. Anything that will burn longer than a match after it is lit from a match, can be considered. CONTAINER AND INCENTIVE FOR HEATING FLUIDS l. A couple of tin cans may serve as a container. 2. Aluminum foil - l to 2 feet wide by 2 to 4 feet long is ideal. Wrap kit contents in it. Foil can also be used to form a container. Foil also serves as a crude reflective signaling device, trail marker, book mark, etc. 3. For tea, coffee, soups, sugar, honey to add flavor, morale, vitamins, minerals and energy to your kit. They could make a cold miserable night in the wilderness or in a snowcave much more tolerable. Plus you gain heat and precious energy. SIGNALING DEVICE l. Whistle, shrill type with strong string to be worn around neck. 2. Aluminum foil, reflective signal. 3. Mirror - metal, chromed or brushed. Glass okay, but could be dangerous if it broke. 4018.21 Forestry and Natural Resources Unit 18: Outdoor Safety and Survival Skills CUTTING TOOL A small knife with a couple of sharp blades. Some people always carry a knife, so they would automatically have it along. Keep It sharp - It’s safer, requires less energy to work with, and will do more things for you. MEDICAL SUPPLIES l" wide surgical tape (2 to 3 feet); 4 or 5 Band-Aids; 2 safety pins, needle and thread (for sewing material, not people); salt tablets or salt packages, aspirin; antiseptic ointment; protected razor blade. FIRST AID KIT First aid kit should consist of the following: Amount 6 3 3 3 4 3 2 1 2 1 1 6 1 1 1 1 3 1 Item & Type 1" Adhesive compress 2"x2" gauze pads 3"x3" gauze pads 4"x4" gauze pads 1/2 sq. yd. plain absorbent gauze 24"x72" plain absorbent gauze 1" gauze roller bandage 2" gauze roller bandage 40" triangular bandage 1/2" roll adhesive tape scissors, needle, tweezers, thermometer safety pins small bottle green soap small bottle rubbing alcohol 12 aspirin, package salt tablets, 6 antihistamine tablets small tube hand cream 3"x4" adhesive moleskin sheets box matches 4018.22 Forestry and Natural Resources Unit 18: Outdoor Safety and Survival Skills Being Lost SIGNALING FOR HELP, MAKE YOURSELF SEEN 3 FIRES OR 3 Blasts at regular intervals STAMPED IN SNOW OR SAND Deep-wide & as large as possible. Being lost is not dangerous in itself. . . IN FACT, with the proper mental attitude, it can really be interesting if time isn’t critical and you are SELF SUFFICIENT. THE DANGER IS IN LOSING SELF-CONTROL DANIEL BOONE said, “I’ve never been lost, though I will admit to being confused for several weeks.” 4018.23 Forestry and Natural Resources Unit 18: Outdoor Safety and Survival Skills Hypothermia SYMPTOMS: 1st Stage Intense shivering and very poor muscle coordination. Failing memory and slow thinking. 2nd Stage Too late for self help brain won’t function. 3rd Stage Unconsciousness, low vital signs of life. EMERGENCY EXPOSURE TREATMENT: 1. 2. 3. 4. 5. 6. 7. Recognize danger, know the symptoms Stop, get help. Shelter victim quickly. Remove all wet clothes. Put on dry clothes Induce hot drinks to . . . Restore normal body temperature before traveling again. 4018.24 Forestry and Natural Resources Unit 18: Outdoor Safety and Survival Skills Water Can Demonstration To demonstrate: Heat loss. Fabric comparisons. Wind and water effects. Equipment required: Four 2-gallon metal cans. Thermometer. Enough wool material to cover 2 cans. Enough cotton material to cover 2 cans. Plastic bag big enough to hold 1 can. One piece of foam rubber or styrofoam Wet big enough to form a base for 1 can. Wool Set-up: Record: 1) Fill 4 cans with hot water, note temperature. 2) Wet 1 piece of wool, 1 cotton. Cover 1 can with each. 3) Cover 1 can with seccessive layers of cotton, wool, plastic. Set on insulation. 4) Leave 1 can “naked.” 5) Place all cans in shaded, windy spot outdoors. 1) Initial water temperature. 2) Outside air temperature. 3) Water temperature in each can at 1-hour intervals. Compare: Conclusions: Plastic Bag Thermometer Wet Cotton Naked Can Put all 4 cans through a sprinkler-simulated rainstorm. Radiation, convection and conduction remove the heat rapidly and simulate their effect on the human body undersimular conditions. Different combinations of wet vs. dry, wool vs. cotton, naked vs. protected. Heat loss is greater when wet and or windy. Wool slows heat loss more than cotton. 4018.25 Cotton & Wool Forestry and Natural Resources Unit 18: Outdoor Safety and Survival Skills Emergency Shelters Wind Direction Rock Windbreak Lean-to of conifer bows Use natural materials as they grow for maximum rain run-off. 4018.26 Wickiup Forestry and Natural Resources Unit 18: Outdoor Safety and Survival Skills Snow Shelter Hot Coal Bed Windbreak Dry Grass Ventilation Hole Bed 10” Dirt Layer 3” Deep Snow Cave (X-section) Planned or improvised insulation Fire Shelf Sleeping Shelf 0 Degrees Outside Snow Block 4018.27 Hot Rocks Forestry and Natural Resources Unit 18: Outdoor Safety and Survival Skills Finding Water or liquid is absolutely necessary for life processes.
