Bladder Tank and NFPA 20
(OP)
Can the bladder tank and associated piping for a Hi-Ex foam system be in the same room as the Fire Pump and Controller?
According to NFPA 11 (2005) Section 4.2.2.1 states that pumps shall be installed IAW NFPA 20.
NFPA 20 (2007) Section 5.12.1.1.4 states: "Rooms containing fire pumps shall be free from storage and penetrations not essential to the operation of the pump and related components."
Since a bladder tank "stores" concentrate and neither the tank or the concentrate is essential to the operation of the fire pump, do I have to provide a separate room for the foam equipment?
Based on a strict reading of both standards it appears that I will need separate rooms. Do you agree?

RE: Bladder Tank and NFPA 20
Look at this way: It's a noncombustible tank with a polymeric bladder filled with noncombustible high-expansion foam solution. It presents no additional risk if its considered as a exposure fuel package. Moving into another room means that it may not be inspected at the same frequency as the pump.
