Don’t overload an extension cord with too many appliances plugged into it at once.
Do make sure you are selecting the right type of extension cord for each situation. For example, using an indoor extension cord indoors, and an outdoor extension cord for outdoors.
Don’t use cords that are punctured, frayed, damaged. Throw them away to keep them separate from working cords.
Do choose the right cord length. You should have one extension cord long enough for the appliance you are plugging in. You should never connect multiple cords together.
Don’t pull extension cords out by the cord, always pull it out by the plug when disconnecting it from the outlet.
Do check the wattage rating on your extension cords. Make sure the wattage rating is greater than the appliance’s power requirement.
Don’t run the cords under furniture or carpets to avoid any tripping hazards.
Do read the instructions on the correct use for the cord and it’s power requirements.
Don’t run cords through water or snow to avoid electrical shock.

Don’t use any cords that get hot to the touch.
Do keep cords organized with approved cord bundling or ties. Use labels to distinguish which wires belong to which appliances.

Do cover unused outlets and extension cord plugs with childproof covers when not in use.
Don’t confuse extension cords and surge protectors.
Do store extension cords indoors.
Don’t use extension cords as a permanent solution. Permanent wiring should be installed for long-term electrical use.
