A fire department (United States and Canada) or fire brigade (United Kingdom and Commonwealth) (also known as a fire and rescue service or simply fire service) is a public or private organization that provides predominantly emergency firefighting services for a specific geographic area, which is typically a municipality, county, or fire protection district. Other life safety services, such as technical rescue, hazardous materials, and emergency medical services may also be provided by the agency. In the United States a fire brigade is the private firefighting organization of a company or enterprise, operated under rules from OSHA. A fire department usually contains one or more fire stations within its boundaries, and may be staffed by career firefighters, volunteer firefighters, or a combination thereof (referred to as a combination department).
A fire department may also provide "fire protection" or fire prevention services, whereby firefighters visit homes and give fire safety advice and fit smoke alarms for members of the public. In many countries fire protection or prevention is seen as an important role for the fire service, as preventing a fire from occurring in the first place can save lives and property.
Fire departments are organized in a system of administration, services, training, and operations; for example:
A fire service is normally set up where it can have fire stations and sophisticated fire engines strategically deployed throughout the area it serves, so that dispatchers can send fire engines, fire trucks, or ambulances from the fire stations closest to the incident. Larger departments have branches within themselves to increase efficiency, composed of volunteers, support, and research.
