How to Use Electrical Safety & Prevention When Working in the Workshop

Actions as simple as changing a lightbulb can be potentially fatal if done incorrectly.

Working with electricity safely at the workplace can be a matter of life or death. The Canadian Centre for Occupational Health and Safety points out that "even changing a light bulb without unplugging the lamp can be hazardous because coming in contact with the "hot" or live part of the socket could kill a person." Exactly what procedures to follow will depend on what electrical devices you are using at your workshop.

Things You'll Need

• Electrical tools
• Electrical cords
• Electrical outlets

Instructions

Cords

1. Check to see if any of the power cords are worn. If so, replace them with heavy duty cords because worn cords can be hazardous.

2. Replace an open front plug with a dead front plug or plug cover to reduce the chance of accidental shock.

3. Avoid tripping over cords while using electrical devices.

4. Wrap the cords up when you are finished using them. Do not tie them in a tight knot, as this can cause short circuits.

Tools

1. Check if your tools are damp or wet. If they are, dry them because wet tools are a power hazard. Be sure to store them in a dry area.

2. Switch the tool off before connecting its cord to a power outlet.

3. Disconnect the tool from its power source before making any adjustments.

4. Turn the tool off before unplugging it.

Circuits

1. Check the limits your workshop's circuits can take and do not exceed them to avoid short-circuiting your electrical system.

2. Handle your cords gently to avoid ripping them while in use. Minnesota Power says "never yank, kink, or bend cords. Unwind them fully before use, and store loosely coiled in a dry place."

3. Plug in cords to outlets so that outlets are not overloaded. Do not try to plug too many cords into one outlet, as this can cause short circuiting.

Floor and Grounding

1. Check if there are any puddles or damp spots on the floor of your workshop. If so, this could cause a electrical hazard.

2. Ensure that any electrical devices that need secure grounding are securely attached to the floor before use.

3. Do not turn on outlets on the ground until a device is plugged into them.

4. Switch off the power to the ground outlet before unplugging the device's cord.

Tips & Warnings

• Pull plugs out at their head instead of pulling further down the cord to avoid wear and tear of your cord.

• Do not use extension cords permanently. The National Oceanic and Atmospheric Administration warns that "extension cords must only be used for temporary purposes, not for permanent installation."
