So 18 tanks of 15,000 gallons each? Regardless, if you're under the IBC you're limited to only 240 gallons in the building before the building classification is considered H-2 or H-3 depending on what the particular chemicals are.
Get to that point and you're in a whole new world of building issues protection of structure (passive fire prot), ventilation, electrical classification, definitely containment regardless of occupancy classification, and on and on. You've got potential for two scenarios, pool fire and 3D fire. If you look at the MSDS it should say to use suppression method for surrounding area or to use something specific such as foam or foam-water. You've got more to look at that needs answered than what is here before making a final decision. Craig L.

Think one hell of a party. Got a code reference to a sprinkler density/protection scheme? FM 7-29 references a 7-88 but I can't find any 7-88. NFPA 30 (24.6) doesn't seem to say anything much about this even suggesting it's OK with none (after a hazard analysis, of course). If the goal is to keep a fire not involving the liquid from breaking a tank probably don't need much density. If the goal is to save anything after a tank rupture and fire then foam is probably the only answer. I'd think the code or standard would say something? Most of the building is drums in racks so I think were at .6/3000 plus in-racks. Thinking just extending into this small area has very little cost. Yes, yes I know PE should be involved to specify the approach for the holistic fire protection matters including spill containment, venting, tank specifications, electrical concerns etc. Lets for now assume this is the real ugly world and this party doesn't exist yet.
