Re: Fire Resistance of Roof Supports, Sentences 184.108.40.206.(1) and 220.127.116.11.(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 18.104.22.168., and is fully sprinklered. Clause 22.214.171.124.(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 126.96.36.199.(1), then the requirement for a fire-rated roof is waived. Taking into account Sentence 188.8.131.52.(1) and Clause 184.108.40.206.(2)(c) we consider that the waiver must also apply to the supports for the roof.
