Todd: I have run into this exact same thing on a couple of apartment jobs. We were able to do exactly as Greg described. The owner held the walls so that they were more than 18" below the deflector and we treated as a large room calc'd to OH2 (you never know what people will put in these things). We even went this route on a retrofit. The GC cut the walls down as we needed and put up chain link fencing.
It worked pretty good. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Todd Williams - FPDC Sent: Friday, February 22, 2008 3:05 PM To: [email protected] Subject: Gaggle of closets I am looking an apartment building which is to be designed according to NFPA 13. On the first level, there is a room which contains 55 - 3'x5' tenant storage closets (mostly filled with shelves). These would need to be sprinklered, which is fine, but the issue comes in the hydraulics. Section 14.4.4.4.2 states that closets with a single sprinkler may be omitted from the calculation. There could be up to 47 closets in the remote area. I have used this exception numerous times, but never in this quantity. The standard says nothing to the contrary, so I could eliminate 47 sprinklers in the remote area because they are in closets? Is there something I am overlooking? Todd G.
