Just the Facts The Occupational Safety and Health Administration states that most injuries on construction sites involve excavation cave-ins, power tool accidents, falls, electrical hazards, and exposure to potentially dangerous materials Working with power tools, you can get an electric shock, lose a finger, lose an eye, or go deaf. It's especially dangerous to use a tool that's defective, that's been modified, or that's not designed for the job. Of course, you can also get injured if you use any tool carelessly.

General Safety Guidelines for Power Tools Be aware of all power lines and electrical circuits, water pipes, and other mechanical hazards in your work area, particularly those below the work surface, hidden from the operator's view, that may be contacted. Wear proper apparel.

Do not wear loose clothing, dangling objects or jewelry. Long hair must be restrained. Gloves should not be worn when operating certain power tools. Check appropriate tool manuals. Spark Resistant Tools Around flammable substances, sparks produced by iron and steel hand tools can be a dangerous ignition source. Where this hazard exists, sparkresistant tools made from brass, plastic, aluminum, or wood will provide for safety. Preferred "non-sparking" metals have less tensile strength than steels usually used to make tools.

A lower tensile strength means the metal has less strength or resistance to tearing apart when stretched under test conditions. It also means that these tools are softer, wear down more quickly than ordinary steel tools, and have to be dressed more frequently. Most Dangerous Powered Hand Tool? HINTS 1. Operating temperature can reach degrees F. Parts can move up to 68 miles an hour 3.

Switches Hand-held power tools must be equipped with one of the following: Constant pressure switch shuts off power upon release Examples: circular saw, chain saw, grinder, hand-held power drill On-Off Switch Examples: routers, planers, laminate trimmers, shears, jig saws, nibblers, scroll saws OSHA Office of Training and Education 25 Would you use this extension cord?

Extension cords will be used as needed for temporary power only, and must be stored properly when not in use. Waste will be disposed of in the appropriate receptacles. All work areas and walkways will be well lit. Hand Tools Hand tools are non-powered or operate only through physical exertion by hand. Hand tool precautions include the following: Use the right tool for the job. Saw blades, knives, and other sharp tools will be directed away from aisle areas and other employees working in close proximity.

Knives and scissors will be kept sharp; dull tools can be more hazardous than sharp ones. Only spark-resistant tools made from brass, plastic, aluminum, or wood will be used around flammable substances. Wrenches, including adjustable, pipe, box-end, and socket-style wrenches, will not be used when the jaws or socket are stripped or sprung in such a way that slippage occurs.

Impact tools such as drill pins or punches, wedges, and chisels will be kept free of mushroomed heads. Wooden-handled tools will be kept free of cracks and splinters and will be kept tightly attached to the working end of the tool.

Tools will be stored in appropriate storage areas when not in use. Portable Power Tools A portable tool is one that requires a power source to operate, such as electric, pneumatic, liquid fuel, hydraulic, explosive-actuated, and powder-actuated device or power supply. Examples of regulated portable power tools include: Portable abrasive wheels and grinders Lawn mowers Powered drills Portable circular saws Portable belt sanding machines Explosive-actuated fastening tools Jacks Abrasive blast cleaning nozzles Power tool general precautions include the following: Read the owner's manual to understand the tool's proper applications, limitations, operation, and hazards Use the right tool for the job.

Inspect tools prior to each use. Inspection will include the power cord and plug. Wear proper eye and face protection while operating power tools. Never carry a tool by the cord or hose. Never yank the cord or the hose to disconnect it from the receptacle. Never stand in or near water when operating tools. Keep cords and hoses away from heat, oil, and sharp edges. Electric power tools will be either three-wire grounded or double-insulated and must be listed by Underwriters' Laboratories or another recognized listing agency.

Disconnect tools and ensure a zero-energy state when not in use, prior to servicing and cleaning, and when changing accessories such as blades, bits, and cutters. Keep unauthorized persons away from the work area by using signage, barricades, stanchions, keyed access, etc. Avoid accidental starting; do not hold fingers on the switch button while carrying a plugged-in tool. Maintain tools with care; keep them sharp and clean for best performance. Never leave tools unattended with parts still moving; even after the machine is turned off, some parts may still be capable of moving.

Maintain good housekeeping practices by keeping the work area free of debris or other items that can get caught in tools or power equipment. Follow instructions in the user's manual for the tool when lubricating and changing accessories. Maintain good footing and balance when operating power tools. Do not wear loose clothing, ties, or jewelry when operating portable power tools; such items can become caught in moving parts.

Remove all damaged or defective portable electric tools from use and tag them: "Do Not Use. Always plug cord-connected, hand-held electric tools into ground-fault circuit interrupter GFCI -protected receptacles or in compliance with the facility's assured electrical grounding conductor program. Cup wheels Types 6 and 11 will be protected by safety guards or special "revolving cup guards" which mount behind the wheel and turn with it.

They will be made of steel or other material with adequate strength and will enclose the wheel sides upward from the back for one-third of the wheel thickness. Belt sanding machines will be provided with guards at each nip point where the sanding belt runs onto a pulley. Never clamp a hand-held grinder in a vise.

When operating a riding-rotary mower, never make sharp turns at high speeds, especially on a hill. Never put hands or feet under a running mower. Always shut off the mower and disconnect the spark plug before servicing or reaching under the mower deck.

Guards Hazardous moving parts of a power tool need to be safeguarded. Guards, as necessary, shall be provided to protect the operator and others from the following: Point of operation Nip points Rotating parts Flying chips and sparks Power tool guarding precautions include the following: Always consult supervisor when the manufacturer recommendations for guarding a specific power tool are not available or cannot be implemented. Guards must not be removed or bypassed unless the power tool is unplugged or locked out from the power source and is in a zero-energy state.

Notify a supervisor immediately when any unguarded moving parts or dangerous points of operation are observed. Stop work and shut down the tool until the condition is corrected. Do not use unauthorized or damaged guards. Operate power tools only when all guards are in place and properly attached according to the manufacturer's recommendations, and are functioning properly.

If a guard is damaged, bypassed, or missing, the tool will be removed from service and tagged with "Do Not Use" until repairs can be made. Safety Switches All hand-held power tools will be fitted with any one of the following safety switch methods as appropriate for the particular tool: A momentary contact "on-off" control. A lock-on control provided that turnoff can be accomplished by a single motion of the same finger or fingers that turn it on. A pressure switch which requires constant pressure to run and will shut off when the pressure is released, such as required for hand-held gasoline-powered chain saws.
