BCAB #1308 - Protection of Combustible Sprinkler Pipe, Sentence 126.96.36.199.(3)

Re: Protection of Combustible Sprinkler Pipe, Sentence 188.8.131.52.(3)
The project in question is a four storey wood frame apartment building designed under Article 184.108.40.206. of the 1992 B.C. Building Code. The building will be sprinklered in accordance with Sentence 220.127.116.11.(2) and NFPA 13R.
Sentence 18.104.22.168.(3) requires combustible sprinkler piping to be "... separated from the area served ... and from any other fire compartment by ceilings, walls, or soffits ...".
The appellant contends that the plastic sprinkler pipe does not have to be separated from the attic space, but only from the rooms below.
Building Official's Position
The building official maintains that the attic is, by definition, a fire compartment. Therefore, the plastic sprinkler pipe must be separated from the attic by one of the materials listed in Sentence 22.214.171.124.(3) such as gypsum board.
Appeal Board Decision #1308
It is the determination of the Board that the combustible sprinkler pipe is not required to be separated from the attic space. The attic space was not considered to be a fire compartment because it is not enclosed by a fire separation with a required fire resistance rating (there is no fire resistance rating from the attic side to the fire compartments below). The fire rated ceiling membrane is intended to separate the adjacent suites from each other and not from the attic space.
