It’s Electrifying: Take Command of Cords

Our third and final post in our It’s Electrifying series focuses on electrical cord maintenance. Follow these inspection tips to ensure electrical cords are safe to use.


  • Only 3-prong extension cords with correct rating may be used. 
  • Check your cords rating AND the equipment’s amps to ensure the cord is compatible with the equipment.


  • Tools and cords should be inspected on a regular basis to ensure everyone’s safety. Questions to ask during inspection include:
    1. Is there any insulation showing?
    2. Is there any twisting of the wire inside the extension cord?
    3. Is there proper strain relief?
    4. Is the cord wired correctly?

    • Damaged cords or cords showing insulation should be removed from service and tagged, “DO NOT USE” 
    • Tools or cords tagged “DO NOT USE” should be repaired or disposed of immediately.
    • Flexible cords should always be used in continuous lengths without splicing or taping. This means NO ELECTRICAL TAPE should ever be used to splice two lengths together
    • Hard service flexible cords No. 12 or larger may be repaired, if repaired by a designated Competent Person and the cord is repaired back to original quality.


    Taking a few extra moments to inspect the cords on your job site or at home may just save a life.
