Proper Tool Use

Be sure to follow these general rules when using hand tools:

  • Inspect tools before using.
  • Avoid using damaged tools.
  • Tools that appear to be damaged or have broken handles should be marked unsafe and not used.
  • Do not use damaged or defective tools until they have been repaired.

Always use proper-sized tools and equipment for the job. Use each tool only for the job for which it was intended. Forcing a small tool to do the job of a large one may result in injury or tool damage. Below are some more important "don'ts" to follow when using hand tools:

  • Don't use a screw driver to test electrical circuits.
  • Don't use a machinist's hammer in place of a carpenter's hammer.
  • Don't strike a hardened steel surface, such as an anvil, with a steel hammer.
  • Don't use a wrench that is not properly fitted.
  • Don't use pliers in place of a wrench.
  • Don't strike wrenches with hammers or use wrenches as hammers.
  • Don't push on wrenches: pull on them to tighten or loosen nuts or bolts.
  • Don't saw on material unless it's properly secured.
  • Don't place your fingers within striking distance when hammering.
