High-rise structures are divided into two classifications: 1) Life Safety high-rise and 2) Existing high-rise structures. - answer *Life Safety high-rise structures are buildings constructed since 1975. *Existing high-rise structures were built before 1975. *Life Safety high-rise buildings generally have *All Life Safety high-rise buildings have the following components: - answer *the most modern fire protection facilities available. *a) A Building Control Station or fire control room; b) standby power and light for emergency operation of the life safety system; c) a fire department communication system; d) a public address system; e) elevator safety provisions; f) a combined standpipe system; and g)a central station alarm system. *The Building Control Station or fire control room is the *It usually contains the following components: - answer *focal point in Life Safety buildings for fire department operations. *a) A voice communications panel for fire department communications; b) a public address system; a standard hard-wired telephone; c) controls for the building's heating, ventilation and air conditioning system (HVAC); d) fail-safe stairway door release controls; e) displays which indicate the status of the building's fire alarm, HVAC, elevators and stairway door release system; f) building emergency operations manual. Existing high-rise structures may have many of the components of a Life Safety building. Although they may not have a Building Control Station, they may have a lobby console staffed by building security personnel which contains some of the features found in Building Control Stations. *All Existing high-rise structures must have the following: - answer *a) Two means of exit from each floor; b) keys to locked stairwell doors; c) a means of ventilating the structure (operable windows, fixed tempered glass, or mechanical ventilation); d) elevator safety provisions which allows fire personnel access to each floor at all times; e) a Class I and Class II standpipe system, a Class III standpipe system, or a Combined system; and f) an approved warning system or a public address system (a public address system is required in buildings more than 150 feet in height). Each high-rise building is... *required to have an *It should contain - answer *Emergency Operations Manual that is generally located in the Building Control Station, security console, or the building engineer's office. *pertinent phone numbers, floor plans of the building, and other information that could be useful to the fire department. *A standpipe system is a *These systems are classified as - answer *wet or dry system of piping and related equipment designed to provide water exclusively for fire fighting. *Class I (dry), Class II (wet), Class III (combination), and Combined Sprinkler-Standpipe systems. Class I standpipe systems are - answer *found in older high-rise structures four or more stories tall. *It is a dry system with water supply and water pressure delivered by a fire department pumper through inlet connections. *There is a minimum requirement of two 2 ½- inch inlets for fire department pumper connections. *All portions of the high-rise structure must be able to be reached by a thirty- foot stream from a nozzle attached to one hundred feet of hose. Class II standpipes are - answer *required in buildings three or more stories tall. *It is a wet system directly connected to a water source and is equipped with 1 ½-inch outlets with hose and nozzle, for use by the building's occupants. *All portions of the high-rise structure must be able to be reached by a thirty-foot stream from a nozzle attached to not more than one hundred feet of hose. A Class III (Combination) standpipe system is a - answer *wet system directly connected to two separate sources of water. *The primary water supply is connected to the municipal water system and is generally connected to the building's fire pump(s) or to internal tanks which supply the building's fire pump(s). *It is equipped with 1 ½ -inch outlets with hose and nozzle for occupant use and 2 ½-inch outlets for fire department use. *Inlets for fire department pumper connections to the standpipe system are required and are considered a secondary source of water. A Combined Sprinkler/Standpipe system is - answer *required in all high-rise buildings greater than 75 feet tall and built after July 1974. *Automatic fire sprinklers are required. High-rise structures over 150 feet tall must have a combined system directly connected to a water supply and must have 2 ½-inch outlets for fire fighter use. *It will have fire department inlet connections, a fire pump which supplies water and water pressure to the standpipes and an on-site water supply. *High-rise structures 75 to 150 feet in height may utilize the wet standpipe to supply the sprinkler system.
