DIFFERENCE BETWEEN Hand Tools
AND Power Tools
Hand tools
Have no power source, other than the physical force applied by the user. Hand- tools include anything from axes to hammers, and screwdrivers to wrenches.
Power Tools
Require a non-human power source to function properly--e.g. External (electricity, compressed air, etc.) or Internal (battery pack, internal combustion engine, etc.).
Both kinds of tools require specific safety precautions or rules to be followed; yet some rules will apply to both.
There are seven basic rules that apply to all tools used either hand or power.
Keep all tools in good working order
Use the tool only for what it is designed to do
Examine the tool for damage before each use
Always follow the manufacturer’s instructions when operating any tool
Wear proper apparel. Do not wear loose clothing, dangling objects or jewelry. Long hair must be restrained. NO OPEN TOED SHOES!!
Check with Mr. Lewis if unsure on how to use a tool!!
Appropriate personal protective equipment should be worn due to hazards that may be encountered while using portable power tools and hand tools.
When you are in the back shop you must always wear safety glasses, when tools are in use.
Floors and working areas should be kept as clean and dry as possible to prevent accidental slips with or around dangerous hand tools.
Hand tools are non-powered. They include anything from axes to wrenches. The greatest hazards posed by hand tools result from misuse and improper maintenance.
The greatest hazards posed by hand tools result from misuse and improper maintenance.
Some examples:
Using a screwdriver as a chisel may cause the tip of the screwdriver to break and fly, hitting the user or other employees.
If a wooden handle on a tool such as a hammer or an axe is loose, splintered, or cracked, the head of the tool may fly off and strike the user or another worker.
Wrenches must not be used if the jaws are sprung, cracked or twisted
Impact tools such as chisels, wedges, or drift pins are unsafe if they have mushroomed heads. The heads might shatter on impact, sending sharp fragments flying.
SAFETY RULES For SPECIFIC
Hand Tools
HAMMERS

CHISELS
The greatest hazards posed by hand tools result from misuse and improper maintenance.
Use only chisels that are sharp
Do not use chisels with a mushroom head

SCREWDRIVERS
Always ensure the screwdriver fits the head of the screw
Do not hold the work piece against your body while using the screwdriver
Do not use a screwdriver as a punch, chisel, pry bar or nail puller
Do not use a screwdriver to make a starting hole for screws
SAFETY RULES For Hand Tools cont’d
SNIPS / WIRE STRIPPERS
Do Wear safety glasses or goggles when using snips or wire strippers
Do not use as a hammer, screwdriver, wrench or pry bar
Use the correct type of snips for the job
Do not use excessive force when working with the snips or wire strippers.
Soldering
Always wipe off excess solder.
Always make a precise soldering job.
Never take your eyes of the job that you are doing.
Never touch the end of the soldering iron when it is plugged in.
Soldering
Always check the cord for wires that are showing through the protective rubber. Fix with electrical tape and show
Mr. Lewis.
Always put the soldering iron in its station before and after use.
Always soak the sponge, and rinse it out before use of the soldering iron.
Always put up loose hair, never were loose clothing, always wear safety glasses.
SAFETY RULES For Hand Tools cont’d
SAWS
Do not carry the saw by the blade
Do not use any saw that has a dull saw blade
Keep control of the saw by releasing downward pressure at the end of each stroke
Offer more power, adaptability and dependability than ever before.
With enhanced tool performance comes the responsibility to address power-tool safety issues.
Students are responsible for specifying and using power tools and have a responsibility to check out a tool's safety features, then ensure that the teachers safety precautions and common sense are followed at all times.
Power tools can be hazardous when improperly used.
There are several types of power tools, based on the power source they use:
electric, pneumatic, liquid fuel, hydraulic, and powderactuated.
Never carry a tool by the cord or hose.
Never yank the cord or the hose to disconnect it from the receptacle.
Keep cords and hoses away from heat, oil, and sharp edges.
Disconnect tools when not in use, and when changing accessories such as blades, bits and cutters.
All observers should be kept at a safe distance away from the work area.
Secure work with clamps or a vise, freeing both hands to operate the tool.
Avoid accidental starting. Students should not hold a finger on the switch button while carrying a plugged-in tool.
Be sure to keep good footing and maintain good balance.
The proper apparel should be worn. Loose clothing, ties, or jewelry can become caught in moving parts.
All portable electric tools that are damaged shall be removed from use and tagged "Do Not Use."
Check carefully for loose power cord connections and frays or damage to the cord. Replace damaged tool and extension cords immediately.
Tighten the bit securely as prescribed by the teacher. The chuck key must be removed from the chuck before starting the drill. A flying key can be an injury-inflicting missile.
Always hold or brace the tool securely. Brace against stationary objects for maximum control. If drilling in a clockwise -- forward -- direction, brace the drill to prevent a counterclockwise reaction.
Don't force a drill. Apply enough pressure to keep the drill bit cutting smoothly. If the drill slows down, relieve the pressure. Forcing the drill can cause the motor to overheat, damage the bit and reduce operator control.
Only 1 person may use each sander at a time.
Hold the material firmly in your hands and on the table when sanding.
Keep fingers away from the abrasive surfaces on the sander.
Sand on the downward motion side of the disc sander.
Clean up the sander and the floor around the sander when completed
If the blade breaks, keep clear of the blade, shut off the power, and notify Mr. Lewis.
When backing out of a cut keep the wood perfectly straight or follow cut that you have made and pull it out slow and carefully.
Clean up the band saw and the floor around the band saw when completed.
Pneumatic tools are powered by compressed air and include chippers, drills, hammers, and sanders.
One is the danger of getting hit by one of the tool's attachments or by some kind of fastener the student is using with the tool.
Airhose. Hose and hose connections used for conducting compressed air to utilization equipment shall be designed for the pressure and service to which they are subjected.
