Extension Cord Safety Notice: Extension cords are meant for temporary use only and should never replace permanent wiring. Always check a cord for cracks, fraying, or exposed wire before plugging it in, and never use a damaged cord. Do not run extension cords under carpets or rugs, since this hides damage from view and traps heat that can build up and start a fire. Avoid overloading a single cord by plugging in multiple high-wattage appliances at once, and never connect several extension cords together in a line. Outdoor extension cords must be labelled for outdoor use and kept away from standing water. If a cord feels warm to the touch during use, unplug it immediately and stop using it.
