School Planning and Management, 2015
Between 2007 and 2011, the number of fires in educational properties averaged 5,690 per year, according to “Structure Fires in Educational Property,” a September 2011 report by Richard Campbell published by the National Fire Protection Association (NFPA).
Of those 5,690 fires, 4,060 occurred in nursery, elementary, middle or high schools. So, that means 71 percent of the fires that occur in educational structures occur in preK-12 schools.
