Fire police are fire brigade/company members who, based upon their jurisdictional authority, receive sworn police powers, special training, and support firefighting efforts at emergency incidents. In addition to securing firefighting equipment, incident and fire scenes, and the station itself, fire police perform traffic and crowd control. In some jurisdictions, fire police are exterior firefighters and may be called upon at fire scenes to perform any of the duties of an interior firefighter except those that require a self-contained breathing apparatus.

Crowd control and liaison Residents, owners, occupants, relatives, transients, spectators, and the media are among those who may approach the scene of an incident, and fire police prevent them from being harmed or hampering the work of emergency services personnel working at the scene. Since fire police are often the public's first point of contact with the fire department, they must be skilled in public relations. Scene security Fire police may be asked to provide a scene guard in order to prevent looting or theft and monitor unattended fire brigade equipment.
