Regulation Information Power Tool Precautions 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 powder–actuated. Employees should be trained in the use of all tools—not only power tools. They should understand potential hazards and safety precautions to prevent those hazards from occurring. The following general precautions should be observed by power tool users: • Never carry a tool by the cord or hose. • Never yank the cord or the hose to disconnect from the receptacle. • Keep cords and hoses away from heat, oil, and sharp edges. • Disconnect tools when not in use, before servicing, and when changing accessories such as blades, bits, and cutters. • All observers should be kept at a safe distance from the work area. • Secure work with clamps or a vise, freeing both hands to operate the tool. • Avoid accidental starting. The worker should not hold a finger on the switch button while carrying a plugged–in tool. • Tools should be maintained with care. They should be kept sharp and clean for the best performance. Follow instructions in the user's manual for lubricating and changing accessories. • 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 and tagged "Do Not Use."
