Various elements which may either increase or reduce the intensity or ferocity of fire are taken into consideration. For example, if the property has fire insurance, it is the maximum loss expected at a given location in the event of a fire there.

For example, for fires, these could include the proximity to a fire station, alarms, and sprinklers.
