"Fire departments provide an invaluable service to our communities nationwide by responding to fire incidents in structures, outside areas, vehicles, and other areas. In 2004, the estimated 1,550,500 fire incidents required an estimated 1,847,300 fire department runs. This topical report profiles these fire department fire runs as reflected in the National Fire Incident Reporting System (NFIRS) 2004 data."
