What is the minimum nozzle discharge volume allowed for live fire training evolutions?

• A. 60 GPM
• B. 75 GPM
• C. 95 GPM
• D. 100 GPM

Answer: (C)

Water application rate is critical for safety and for achieving realistic control of the fire in live-fire evolutions. NFPA 1403 sets a minimum nozzle discharge volume of 95 gallons per minute to ensure there is enough water to cool fuels, control the flame front, and maintain tenable conditions for occupants and instructors during training. This baseline helps prevent situations where too little water allows the fire to grow or reflash, which could compromise safety and learning. Higher flows are permissible and may be used, but 95 GPM is the threshold that guarantees the necessary cooling and extinguishing capability in typical training scenarios.
