Every year, electrical fires result in thousands of injuries, hundreds of millions of dollars in property damage and, in some cases, even death. While some fires are caused by faulty products, many more are caused by the misuse and poor maintenance of electrical equipment, incorrectly installed wiring, overloaded circuits and misapplied extension cords. Smoke alarms, fire extinguishers and escape ladders are all examples of emergency equipment used in homes to take action when a fire occurs. A device called an Arc Fault Circuit Interrupter, or AFCI, is a residential circuit breaker designed to detect arcing faults and thus prevent fires from occurring in the first place. Arcing can occur when you're hanging a picture and inadvertently pierce a wire in the wall, when old wires fray or when you string extension cords together to run fans or space heaters. Approximately 2,300 injuries, 67,800 fires and 485 deaths occur each year that can be associated with home wiring, totaling $868 million in property losses. The Consumer Product Safety Commission (CPSC) estimates that "AFCI devices may address 50 percent or more of these fires."
