n. A fire occurring on or within a building.
Structure fires are sometimes called building fires or, in reference to fire within a building, compartment fires. Wildland fires sometimes cause structure fires when they burn in areas where structures are located near wildland fuel. A structure fire can be the cause of a wildland fire if a structure fire ignited surrounding wildland fuel. The application scope of fire models developed for wildland fires does not include simulation of the burning characteristics of structure fires.
