How does NFPA 16 address pump selection for foam systems?

• A. It requires pumps capable of delivering the required flow and pressure for foam solution distribution.
• B. It allows any pump with any capacity.
• C. It requires all pumps to be diesel.
• D. It prohibits high-pressure pumps.

Answer: (A)

The main concept is ensuring the foam system has enough pump capacity to deliver the required foam solution flow and pressure. NFPA 16 requires that the pump chosen for a foam system can provide the necessary water flow and discharge pressure to move foam concentrate through proportioning devices and through all outlets to the protected areas. This means the pump must be sized to meet the design demand, accounting for friction losses in piping, elevation changes, valve losses, and the need to maintain adequate pressure at the most remote discharge so foam is properly proportioned and effectively discharged. It can also involve considerations for standby or redundant pumps to ensure the system remains operable under demand or power loss. The other statements don’t fit because NFPA 16 does not permit any pump regardless of capacity, it does not require all pumps to be diesel, and it does not prohibit high-pressure pumps.
