Heating equipment is the second leading cause of home fires in the United States. More than 65,000 home fires are attributed to heating equipment each year. These fires result in hundreds of deaths, thousands of injuries and millions of dollars in property damage. 
 
Portable electric space heaters can be a convenient source of supplemental heat for your home in cold weather. Unfortunately, they can pose significant fire and electric shock hazards if not used properly. Fire and electrical hazards can be caused by space heaters without adequate safety features, space heaters placed near combustibles, or space heaters that are improperly plugged in.
 
Safety should always be a top consideration when using space heaters.
