| Application | Application 1: Maximum fire-resistance rating of fire separations that separate exits from
the remainder of the building. This
applies to exits serving floor
areas that are intended for occupancy, including mezzanines as stated in Sentence 3.4.2.2.(1), in buildings described in Sentence 1.3.3.2.(1) of Division A.
Application 2: This also applies to tents and air-supported
structures, as stated in Sentences 3.1.6.1.(1) and 9.10.1.2.(1). |

| Intent | Intent 1: To supersede the requirements of Sentence 3.4.4.1.(1) in
regard to exit enclosures passing through floor assemblies, which are required
by Subsection 3.2.2. to have a 3 h fire-resistance
rating, which would otherwise require the exit enclosure to have a fire-resistance
rating above 2 h, on the basis that the 2 h fire-resistance
rating of the fire separation is considered to provide an adequate level of
protection. |
