To exempt certain exposing building faces from the requirements of Sentences 3.2.3.1.(1) and 3.2.3.7.(1), (2) and (3), which would otherwise require a fire-resistance rating, on the basis that the building has a low fire load, the exposing building face is of noncombustible construction and is not a loadbearing wall. These conditions are to limit the probability that the exposing building face will prematurely fail in a fire situation, which could lead to the collapse of the loadbearing exterior wall, which could lead to the spread of fire from the building to an adjacent building, which could lead to damage to adjacent buildings.
