"This topical report describes characteristics and trends in one- and two-family residential building fires reported to the National Fire Incident Reporting System (NFIRS) from 2005 to 2007, the most recent data available at the time of the analysis. It is useful by itself and as a point of comparison with other residential building categories. Most one- and two-family residential building fires (62 percent) are larger, nonconfined fires, that is, fires that are not contained in pots, stoves, garbage containers, or other containers that confine them. Fires in other types of residential buildings, by contrast, are mostly small 'confined' or contained fires (65 percent). One- and two-family residential building fires also differ from other residential building fires in their cause profiles. While cooking accounts for the cause of 30 percent of all one- and two-family residential building fires, cooking fires play a much larger role in other types of residential buildings, accounting for over 60 percent of fires. Heating and electrical malfunctions (short circuits, arcing, and the like) play a larger role in one- and two-family residential building fires as well."
