Fire Safety Tips

Extension Cords

Extension cords, also refereed to as convenience cords; are intended to be used as a temporary supply to portable electrical devices. The Fire Codes state:

Extension cords shall not be used as a substitute for permanent wiring and shall not be affixed to structures; extended through walls, ceilings, floors, under floors or floor coverings; or be subjected to environmental or physical damage.

With temporary electrical wiring the time period is defined by the authority having jurisdiction and, installed in a manner or means as approved by the authority having jurisdiction.  We typically allow the use of extension cords as temporary power for periods not to exceed 180 days in a calendar year and installed in a manner approved by site electricians.

Extension cords are approved for use during manufacturing process where permanent wiring is not possible.

Prior to placing any extension cord in use you should:

  • Make certain that the cord is rated for the ampacity and voltage for the intended use.
  • Ensure that the ground prong (round pin) is in place.
  • Check the cord for damage to the outer insulation and for flat spots or pinched points on the cord.

After placing the extension cord in use:

  • Keep the cord out of walking paths, doorways or other areas where it may be subjected to physical damage.
  • Place your hand on the cord while it is in use.  If the cord is hot, remove it from use immediately - the cord is over capacity.
  • Shut down the equipment being power by the cord, prior to unplugging the cord from an outlet.
  • Never unplug and extension cord by pulling on the cord.  Grab it by the plug and wiggle it back and forth to free it from the outlet.
