"Americans live, work, meet, and play in structures, relying on them for comfort, safety, and convenience. Fires in homes, office buildings, stores, manufacturing plants, and many other structures are the most deadly, injurious, and costly of all fires in the United States. An estimated 505,500 structure fires occurred in 2000, resulting in $8.5 billion in property loss, 3,500 fatalities, and 19,600 injuries. Based on 2000 data from the National Fire Incident Reporting System (NFIRS), fires in structures account for more than 30% of all fires, but they cause nearly 76% of property loss, approximately 72% of fatalities, and nearly 82% of injuries resulting from fires. Structures include residences (homes, apartment buildings, condominiums, hotels, etc.), assembly buildings, office buildings, schools, businesses, manufacturing facilities, and plants."
