For NFPA Initial Attack Apparatus, what is the pump capacity?

Explanation:
The question tests the pump capacity standard for NFPA Initial Attack Apparatus. NFPA 1901 sets the minimum pump capacity for a pumper intended for initial attack at 750 gallons per minute. That rating is chosen so the engine can deliver meaningful water flow to begin suppression on a typical fire scene and support multiple attack lines while maintaining sufficient nozzle pressure after accounting for friction losses in hoses and fittings. While other equipment might operate with lower pump capacities, the initial attack pumper is designed around 750 GPM to provide reliable early suppression capability. A pump rated at 250 GPM would generally not meet the expected flow needs for initial attack operations.
