If extension cords are used at your workplace or jobsite, workers should be aware of a number of safety “do’s” and “don’ts” before plugging in a cord.
- Check cords for damage before use.
- Ensure cords have the mark of an independent testing laboratory, such as UL.
- Make sure the cord is completely plugged into an outlet.
- Unplug extension cords when not in use, and store the cords indoors.
- Keep cords away from water. Ground fault circuit interrupter protection should be used when extension cords are in wet or damp environments.
- Don’t use a cord outdoors that is marked for indoor use.
- Don’t plug one cord into another.
- Don’t run extension cords through walls or holes in the ceiling, and don’t run them across floors or doorways.
- Don’t force a plug into an outlet.
- Don’t overheat an extension cord.
- Don’t cover a cord with a rug or carpet.
- Don’t drive over an extension cord.
