weather-resistant compartments to store equipment. 2 Initial Attack Fire Apparatus (1 of 6) • Used like a pumper, but with different specifications – Not as common as a pumper, but used by many departments • Smaller version of the pumper and more maneuverable, especially off road • Equipped with four-wheel drive and used to fight fires in urban and rural settings 2 Initial Attack Fire Apparatus (2 of 6) • Many are built on a commercial chassis platform with a custom-built body. – Makes many parts easier to maintain and repair because parts can be found at local auto parts stores • Some are custom built by a private company. • Be aware of the potential for overloading the chassis with too much weight and creating a safety hazard. 2 Initial Attack Fire Apparatus (3 of 6) • NFPA 1901 states that the initial attack apparatus must: – Be equipped with a fire pump as defined in NFPA 1901 – Have the minimum rated capacity of 250 GPM (1000 L/min) – Have a water tank with a minimum certified capacity of 200 gal (750 L) 2 Initial Attack Fire Apparatus (4 of 6) • The apparatus has pumping capabilities, so a hose is required to expel water. • Must carry a minimum of 15’ (4.5 m) of soft suction hose or 20’ (6 m) of hard suction hose with a strainer 2 Initial Attack Fire Apparatus (5 of 6) • NFPA requires these hoses and nozzles: – 300’ (90 m) of 2½” (65 mm) fire supply hose – 400’ (120 m) of 1½” (38 mm), 1¾” (45 mm), or 2” (52 mm) attack fire hose – Two combination spray nozzles with a minimum capacity of 95 GPM (360 L/min) 2 Initial Attack Fire Apparatus (6 of 6) • Needs storage compartments – NFPA 1901 mandates 22+ ft3 (0.62+ m3) of enclosed weather-resistant compartments for equipment. – Compartment space is a custom body that is added to a commercial cab and chassis. • Initial attack fire apparatus is used to bring equipment to the fire scene. – Most tools are the same as found on a pumper. 2 Mobile Water Supply Apparatus (1 of 3) • Many rural communities do not have hydrants or readily accessible water. – Fire fighters need apparatus with largecapacity water tanks. • Mobile water supply apparatus are defined in NFPA 1901. – May be designed with or without a fire pump – If it has a fire pump, it is designed to carry a large capacity of water to the fire scene. 2 Mobile Water Supply Apparatus (2 of 3) • Mobile supply apparatus with fire pump carries 15+’ (4.5+ m) of soft suction hose or 20’ (6 m) of hard suction hose with a strainer. • Fire hose and nozzles are also needed. – Must have 200+’ (60+ m) of 2½+” (65+ mm) supply hose – Mobile water supply apparatus with fire pump requires 400’ (120 m) of 1½” (45 mm) or 2” (52 mm) attack hose and two combination spray nozzles with 95+ GPM (360+ L/min) capacity. 2 Mobile Water Supply Apparatus (3 of 3) • Equipment storage is very important. – Must have 20+ ft3 (0.57+ m3) of enclosed weather-resistant compartment space for equipment – Minor equipment must be organized and mounted in brackets or compartments. 2 Aerial Fire Apparatus (1 of 6) • 1830: Abraham Wivell, an English fire fighter, created the first fly ladder. – Reached the second story with main ladder and extended the next two flies to the upper floors • Late 19th century: Scott-Uda designed height extension ladders. – Used eight extensions with weights and balances – Short-lived because many died due to collapses 2 Aerial Fire Apparatus (2 of 6) • 1868: Daniel Hayes successfully patterned an 85’ hand-cranked aerial ladder. – Popularity of mechanics, pneumatics, and hydraulics started the race for a perfect aerial ladder. • Seagraves introduced the first aerial truck. – 1916: American LaFrance used air compression to raise ladders. 2 Aerial Fire Apparatus (3 of 6) • Today’s ladder trucks are equipped with computerized aerial ladders that extend for 110’. • Aerial fire apparatus are defined in NFPA 1901. – Apparatus can be configured in many ways: aerial ladder, elevating platform, water tower, or water pump. 2 Aerial Fire Apparatus © SVLumagraphica/ShutterStock, Inc.
