Power Tools (Electric)

Mishap Data

• The most common power-tool accident involves injuries to the fingers. About half of all finger amputations in the U.S. each year involve a power tool, usually a saw. Of these finger injuries, 55% occurred while operating the power tool at home.
• Many power-tool injuries occur because the user doesn’t remove the power source while changing parts on or adjusting the tool.

Do’s and Don’ts

• Insulation is a primary protection against electric shock, but it can get worn or cracked. Inspect it regularly. Look for frayed cords on power tools.
• Replace damaged electrical equipment or have it repaired at an authorized repair center. Replace frayed cords, broken plugs or cracks that could cause hazards; cut and throw out damaged cords.
• Plug grounded (3-wire) tools only into grounded outlets.
• Don't pick up power tools by their power cords.
• Don't work with electric tools when it’s raining.
• Don’t lose concentration when using a power tool. If you get tired or distracted, take a break until you can focus.
• Beware of inexperience and overconfidence.
• Keep all tools in good condition with regular maintenance.
• Use the right tool for the job.
• Operate tools according to the manufacturer’s instructions.
• Use the right personal protective equipment: safety goggles dust masks, hearing protection.
• Don’t turn on a power tool until guards are in place.
• Never remove or bypass a tool guard.
• Don’t use a malfunctioning power tool—fix it or replace it.
• Unplug power tools before adjusting them.
• Use a vise or clamps to secure materials so that you can use both hands to operate the tool.
• Turn off a power tool before you put it down.
• Keep your finger off the switch when you carry a plugged-in power tool.
