Extension Cords

Extension cords provide a convenient method of bringing temporary AC power to a device that is not located near a power outlet. If not used properly, extension cords can lead to electrical shock hazards, equipment damage and fire hazards. In addition, improper cord selection can lead to use of an undersized extension cord, resulting in an overheated cord and insufficient voltage delivered to the device. This condition can result in a device or cord failure and fire.

The U.S. Consumer Product Safety Commission (CPSC) estimates that about 4,000 injuries associated with electric extension cords are treated in hospital emergency rooms each year. About half the injuries involves fractures, lacerations, contusions or sprains from tripping over extension cords. CPSC also estimates that about 3,300 residential fires originate in extension cords each year, killing 50 people and injuring about 270 others. The most frequent causes of such fires are short circuits, overloading, damage or misuse of extension cords.

William & Mary is not immune to extension cord hazards. Improper extension cord use is identified as one of the most noted electrical code and safety findings on campus during EH&S inspections. It is up to all of us to use extension cords properly and safely.
