Do not use a wrench if the jaws are sprung. Do not use impact tools, such as chisels, wedges, or drift pins, if their heads are mushroom-shaped. The heads may shatter upon impact. Direct saw blades, knives, and other tools away from aisle areas and other employees. Keep knives and scissors sharp.
Dull tools are more dangerous than sharp tools.
Iron or steel hand tools may cause sparks and be hazardous around flammable substances. Use spark-resistant tools made from brass, plastic, aluminum, or wood when working around flammable hazards. Improper tool storage is responsible for many shop accidents. Do not place unguarded cutting tools in a drawer. Many hand injuries are caused by rummaging through drawers that contain a jumbled assortment of sharp-edged tools.
