Non-print equipment & services: Extension cord safety checklist

• Check cords regularly for damage or deterioration.
• Use extension cords only as necessary and only on a temporary basis. Never use as a substitute for permanent wiring.
• Do not fasten cords to a building or structure.
• Use a three-prong cord for equipment that has a grounded three-prong plug.
• Always grasp the plug to disconnect an electrical cord from an outlet, never pull on the cord to disconnect the plug.
• Insert plugs fully so that no part of the prongs are exposed when the cord is in use.
• Never place a cord under rugs or furniture or string it through doorways, windows, walls, ceilings, or floors.
• Do not try to repair a damaged extension cord or splice two wires together. Damaged cords are a potential fire or shock hazard and should be placed immediately.
• Avoid plugging two plugs together to make a longer one. Extension cords which are connected to one another, or that are too long will reduce operating voltage and the efficiency of equipment.
• Use an extension cord with the correct size wire (gauge) for the intended use. Do not overload an extension cord or use a light, “household” cord to operate heavy-duty machinery. Overloading may cause excessive heat that may result in a fire.
• Be sure to check the cord's tag or package for the maximum current and/or wattage rating of the cord.
• Purchase and use the right cord for the job. Extension cords are sold in various cable sizes which are identified by numbers. Smaller numbers indicate larger wire sizes. For example, a number 10 wire is larger than a number 14.
• Use good housekeeping practices, such as taping down exposed cords with duct tape, to prevent damage to extension cords and to keep cords from becoming tripping hazards.
• Ensure the extension cord is used in a dry area.
• Keep cords away from sharp objects, heat, oil, and solvents that can damage insulation.
• Inspect all extension cords which have been used off site.
• Do not allow anything to rest on, or roll over power cords.
• Never force a plug into an outlet or extension cord.
• Check floor outlets frequently for damage or caked in dirt.
