|Extension cords are a very important part of any construction site, but when used improperly they may cause injury or even death. Just like any tool, extension cords must be visually inspected every day for recognized hazards.|
They must be free from cuts. The only tape should be the one being used as part of the Assured Grounding Program. Extension cords that have cuts or missing prongs should be replaced. When possible, extension cords should be run overhead and be secured with plastic or rope ties. Never secure them with metal wire, to building steel, strut or other conductive material.
Cords passing through holes, door frames and gang box holes must be protected from cuts. If cords are run on the floor they should be secured with tape or other means to prevent trip hazard.
Cords being run on the ground should stay out of walk paths and out of water. When using extension cords that are classified as temporary power, a GFCI needs to be used unless the outlet has a built-in GFCI.
