Just to reiterate Scott's point: Maintenance is huge and his examples are extremely valid. We were once painted into a corner on our first foam job many years ago. The foam tanks were put on a mezzanine above the risers. But we ensured there was plenty of room on the mezzanine for bladder removal, and double doors on the exterior wall of the mezzanine for better access to remove/replace bladders or tanks (via fork lift). Not ideal, but serviceable.
(BTW - my favorite example of lack of maintenance foresight is a foam job (by others) which included a vertical bladder tank located below a second level - with about 2 ft. of clearance above the tank. When the bladder needs replacement, the entire tank will have to be disconnected and removed from the building. There may also be some other piping that needs removal to allow this to happen. Of course, this is a non-issue if you simply blow-off maintenance...). Mark A.

I have two possible Aces up my sleeve. IFC 2009 509.2: Equipment Access.

This site has a dedicated fire service who act as first response to all the client facilities who occupy this industrial park. They are the AHJ for the park. They will be contacted to get their input. There is also the State Fire Marshal's office that also has input. Second is the fact that the proposed location provides no way to bring (6) 4" lines into the building. So I've got some ammo to shoot down this concept. Craig L.

No code restrictions, but certainly foam systems concerns. 55 gallon drums to second floor with stairs? Bladder tanks? Lay 'em down to replace bladder that gets torn. Craig, am I missing something? If not, I've seen this before and it gets ugly real fast. I've worked on an existing hanger that they buried the big tanks in a corner, tore the bladder and have to cut the roof open to lift them out, to lay it down, to replace it.
