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+ ft 3 (0.62+ m 3 ) 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 large- capacity water tanks. Mobile water supply apparatus are defined in NFPA –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.
