Electrical Safety

What are some tips for working with power tools?

• Switch all tools OFF before connecting them to a power supply.
• Disconnect and lockout the power supply before completing any maintenance work tasks or making adjustments.
• Ensure tools are properly grounded or double-insulated. The grounded equipment must have an approved 3-wire cord with a 3-prong plug. This plug should be plugged in a properly grounded 3-pole outlet.
• Test all tools for effective grounding with a continuity tester or a Ground Fault Circuit Interrupter (GFCI) before use.
• Do not bypass the on/off switch and operate the tools by connecting and disconnecting the power cord.
• Do not use electrical equipment in wet conditions or damp locations unless the equipment is connected to a GFCI.
• Do not clean tools with flammable or toxic solvents.
• Do not operate tools in an area containing explosive vapors or gases, unless they are intrinsically safe and only if you follow the manufacturer’s guidelines.

 

What are some tips for working with power cords?

• Keep power cords clear of tools during use.
• Suspend extension cords temporarily during use over aisles or work areas to eliminate stumbling or tripping hazards.
• Replace open front plugs with dead front plugs. Dead front plugs are sealed and present less danger of shock or short circuit.
• Do not use light duty extension cords in a non-residential situation.
• Do not carry or lift up electrical equipment by the power cord.
• Do not tie cords in tight knots. Knots can cause short circuits and shocks. Loop the cords or use a twist lock plug.
