One-alarm, two-alarm, three-alarm fires, or higher, are categories of fires indicating the level of response by local authorities, with an elevated number of alarms indicating increased commitment of resources. The term multiple-alarm is a quick way of indicating that a fire was severe and difficult to contain. This system of classification is common in the USA among both fire departments and news agencies.
