Power sources will also be protected from oil, chemicals, and hot surfaces to the best extent possible. When a power source contacts chemicals or oil, the chemical or oil will be removed as soon as possible. Supervisors will ensure that each user of a portable power tool is trained in proper selection, limitations, and use. Such training will emphasize tool selection, tool inspection, proper use, and required protective equipment. Replace damaged or inadequate plugs before use.
Check switches with the tool unplugged.
Switches should be free of excessive drag, binding, loose mountings, and obvious defects. Check chucks, collets, etc., for proper operating condition and ensure that the correct keys and wrenches are available. Visually check housing for defects and damage. Resharpen blades, bits, etc., and reinstall according to manufacturer's instructions. Tools found to have defects during an inspection will be removed from service, tagged, and turned in to the tool crib for repair or replacement.
