A fire station (also called a fire house, fire hall, or firemens hall) is a structure or other area set aside for storage of firefighting apparatus such as fire engines and related vehicles, personal protective equipment, fire hoses and other specialized equipment. It may also have dormitory living facilities and work areas for the use of fire fighters. Living areas are sometimes arranged above the garage bays where personnel without specific station duties during the night shift are allowed to sleep unless a dispatch is called. In that situation, firefighters may have special means to allow entry to the ground floor quickly when a call for help is received, such as sliding down a brass pole called a firemans pole. This arrangement also allows for a raised area to hang hoses to dry to prevent damage. In a single story station, a tower-like structure is sometimes used for hose hanging.\rbr\rbrAn occupied station will usually have a station alarm system for receiving and annunciating an alarm, and indications of where and what caused the alarm. However, sometimes the only alarm is a telephone that is rung in case of emergency. In a volunteer fire department where volunteers do not staff the station, the firefighters may be summoned to the fire station by siren, radio or pagers, making a station alarm system superfluous.
