"Using the past 3 years of data, for 2003 to 2005, from the National Fire Incident Reporting System (NFIRS) database, the yearly national fire loss for fires on nonadult school properties is estimated at $85 million. Such losses are the result of an estimated annual average of 14,700 fires that required a fire department response. Fires on school properties caused an average of approximately 100 injuries. No fatalities were reported to NFIRS during this period. Forty percent of these school-related fires occurred outdoors on school property. Trash fires accounted for 36% of these out-side fires, and fires in open fields or woods accounted for an additional 19%. Forty-three percent of fires on school properties, an estimated 6,300 fires, were structure fires. Slightly over half of these structure fires were confined to the object where the fire started, such as a small cooking fire (20%) or a fire confined to a trash can (28%). Six percent of fires on school properties were vehicle fires."
