Wooden handles must not be split, cracked, or splintered and must fit securely in the head. Metal handles must not be bent or dented in ways that create hazards. Chisels, punches, and cutting tools must be kept sharp and must not be used with damaged or mushroomed heads that could separate during use. Screwdrivers must have properly fitting blades that match the screw head and must not be used as pry bars or chisels. Pliers, wrenches, and other gripping tools must have secure handles and must not be used beyond their intended purpose or on fasteners larger than the tool is rated for. Tools must be regularly inspected for defects and damaged tools must be removed from service immediately. Work shoes must be worn when using hand tools to prevent foot injury from drops. Proper work techniques must be taught to reduce repetitive strain injuries and carpal tunnel syndrome. Tools must be stored safely and not left in locations where they could fall or cause tripping hazards. Personnel must be trained on proper selection and use of hand tools appropriate to their work tasks. Defective tools must never be repaired and used; they must be replaced with tools in safe condition.
