Re: Fire Resistance of Roof Supports, Sentences 220.127.116.11.(1) and 18.104.22.168.(1)
With reference to your letter of May 8, 1989 regarding the fire rating of supports for an unrated roof assembly.
It is stated that the building in question falls under the provisions of Article 22.214.171.124., and is fully sprinklered. Clause 126.96.36.199.(2)(c) requires that the roof have a 1 hour fire-resistance rating, and (d) that supports be equally rated. However, if the sprinkler system complies fully with Sentence 188.8.131.52.(1), then the requirement for a fire-rated roof is waived. Taking into account Sentence 184.108.40.206.(1) and Clause 220.127.116.11.(2)(c) we consider that the waiver must also apply to the supports for the roof.
