Approximately 8% of the company’s accidents were caused by hand tools. There are four main causes of injuries that occur from using hand tools:

1. Using wrong tool-screw driver for a chisel, or wrench for a hammer

2. Using tools in poor condition-dull chisels, cracked hammer handles, broke or frayed electric power cords and plugs

Safety Tips for Hand and Power Tools

Turn them in for repair or replacement or at least tag them as being defective. Some examples of unsafe tools are:

  • Wrenches with sprung jaws
  • Drift pins, wedges, chisel, and hammers with mushroomed heads
  • Tools with cracked, broken or loose handles
  • Frayed electrical cords or broken grounds


Safety clips, chains or retainers on air hose and pneumatic power tools shall be used to prevent them from becoming accidentally disconnected.

Don’t use compressed air or steam to clean your clothes or shoes.

When using fuel powered tools, be careful when working in enclosed spaces. Make sure you have enough ventilation and always shut the engine off when you refuel it.

Don’t exceed the manufacturer’s limits on hydraulic tools such as jacks or safe operating pressures for hoses, valves, pipes and fittings.

Use extreme care when using explosive actuated tools. Test them each day before you use them. Never point them at anyone and load them just prior to use. Don’t try to drive fasteners into very hard, brittle or extremely thin materials. Use eye protection.

Use safety glasses and face-shields when operating grinding wheels. When it is equipped with a work rest, make sure it is kept within one-eighth inch of the wheel.

Never use any power tools unless all guards are securely in place. This especially applies to all power saws whether portable or bench mounted.

Don’t use a tool you are unfamiliar with. Ask your supervisor for assistance.
