Anyone have any suggestions on a fire pump being located inside a building and 70000 gallon tank under a building.There is no direct access into the room. Everything I am seeing is that the room needs to be 2 hr rated and less that 12 feet from an exterior wall. I am kinda new at this. Looked pretty far into NFPA 22 and NFPA 24. Just looking if anyone can point me in the right direction. Ohio Building Code just said installation needs to reflect 22 and 24.
