Safety tips

  • Unplug appliances when not in use.

  • Look for the UL Mark on all products. It means that samples of the product have been tested for safety.

  • Make sure outlets are not overloaded.

  • Check electrical wires and cords on appliances, tools, lamps, etc. to make sure they're not worn or frayed.

  • Never run electrical wires or extension cords under carpets or heavy items.

  • Never bunch electrical wires or extension cords behind a hot appliance.

  • Use outlet plug covers to prevent children from inserting objects into outlets.

  • Extension cords are meant for temporary use only.
    • Look for the UL Mark on extension cords that you purchase. The UL Mark means that representative samples of the cord have been tested for foreseeable safety hazards.

    • Store all cords indoors when not in use. Outdoor conditions can deteriorate a cord over time.

    • Never keep an extension cord plugged in when not in use. The cord will conduct electricity until it is unplugged from the outlet.

    • Most newer, indoor cords with more than one outlet have covers for the unused openings — use them. Children and pets face serious injury if they chew on unused outlets or stick sharp metal objects into the openings.

    • Do not use extension cords that are cut or damaged. Touching even a single exposed strand of wire can give you an electric shock or burn.
