-----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Justin Reid Sent: Tuesday, April 28, 2009 9:22 AM To: [email protected] Subject: Re: Rating of the sprinkler escutcheon There is an exception in the building code that allows the penetration created by a sprinkler head (with escutcheon) through a horizontal assembly to not be fire sealed ( I believe in Chapter 7 somewhere IBC). It sounds like your sprinkler head may be a sidewall and penetrating the stair shaft wall. I would have to check and see if the same exception applies for vertical assemblies ( I think it does) and make sure that there are no other special situations concerning penetrating the exit (stair shaft wall).
