Home electrical fires claim lives every year. Most are caused by incorrectly installed wiring, or overloaded circuits or extension cords. In other words, most electrical fires are preventable. Fire deaths are highest in the winter as people spend more time indoors, increasing lighting, heating and appliance use. For example, supplemental heaters pull the same 1,500 watts of electricity as a hair dryer, and are often used for longer.

The deadliest house fires begin in living areas. Common culprits include heaters, high-tech games, computers, speaker systems and decorative lighting.
