"In 2002, approximately 30% of reported structure fires first ignited in a kitchen and accounted for 12% of deaths, 32% of injuries, and 10% of property loss. As a fixture of modern homes, restaurants, institutions (e.g., schools), food manufacturers, and some office environments, kitchens introduce the risk of cooking fires to a range of structures. This topical report examines the characteristics and frequency of kitchen fires and compares them with structure fires and all fires generally."
