Keep ignitable materials away from heat-producing appliances. Know where the nearest fire extinguisher is and how to use it. See Chapter 6940 Portable Fire Extinguishers , for more information. Don't overload electrical outlets. Extension cords should only be used as a temporary measure while you await additional receptacles.
Cords have their gauge and classification embossed into the outer jacket.
Never place cords beneath carpet. This can cause overheating of the wire insulation and cord damage that cannot be seen. Power strips are acceptable for simultaneous use of several low-current devices such as computers and their peripherals. Inspect your own equipment's cords and plugs periodically. Look for damaged cord jackets, loose or broken plug blades, evidence of overheating, and separation of the plug from the cord.
