From the County of Prince William:
Outdoor cooking is an experience everyone should enjoy, yet all too often, fire and injuries occur turning a festive event somber. In 2004 – 2008, according to the National Fire Protection Association (NFPA), U.S. fire departments responded, annually, to an average of 7,700 home fires (3,200 structure fires and 4,500 outside fires in or on home properties) that involved grills, hibachis or barbeques. These fires resulted in an annual average of 13 deaths, 120 injuries and $70 million in property damage.
In comparing grills, charcoal versus gas, gas grills resulted in a higher number of home fires (6,200) due to leaks and breaks. Charcoal or other solid-fueled grills resulted in 1,300 structure fires during this time period.
