"School building fires are a subset of school property fires (i.e., school structure fires). School property fires may include structure fires; vehicle and outside fires that occur outdoors on school property; and other, miscellaneous fires. It is important to note that not all structures on school properties are necessarily school buildings. For example, other structures on school properties may include maintenance buildings or playground structures. This report includes brief background information on all school property fires, with the focus of the report on school building fires."
