-----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Todd Williams Sent: Monday, February 13, 2012 2:58 PM To: [email protected] Subject: Interior canopy obstruction I am working on a facility where they are installing some new offices in an industrial building. Around the perimeter of the offices is a canopy which extends out 2'-6" from the office walls. The canopy height is about 9'-6" and the ceiling sprinklers are at 18'-9". The question is do we need sprinklers below the canopies. Section 8.6.5.3 says that sprinklers need not be installed if the obstruction is less than 4'-0" wide. I can go along with it except in one area it covers 1/2 of a 5'-0" wide corridor. In that situation, I would think that sprinklers would be necessary. But I get the "if it's less than 4'-0"....." argument. Any thoughts? Todd G.
