BCAB #951 - Combustible Piping, Sentences 220.127.116.11.(1) & 18.104.22.168.(1)

Re: Combustible Piping, Sentences 22.214.171.124.(1) & 126.96.36.199.(1)
With reference to your letter of October 24, 1987, regarding plastic piping located above a dropped ceiling. Refer also to Appeal No. 947 for some general provisions applicable to this appeal.
Combustible piping would be acceptable if located above a dropped ceiling only if the ceiling did not form a required component of a fire separation. A horizontal separation often consists of a floor/ceiling assembly, with the entire assembly providing a required fire resistance rating.
If therefore the ceiling formed part of a fire separation, then Sentences 188.8.131.52.(1) and 184.108.40.206.(1) would apply, necessitating testing with the piping included. In addition, the provisions of Sentence 220.127.116.11.(1) could be applicable.
