Objective

OS1 Fire Safety

Attribution

[F20,F22-OS1.2]Applies to assemblies required to provide fire resistance.

Intent

Intent 1:

To limit the probability of inadequate lateral stiffness of masonry walls, which could lead to an inability to resist lateral loads or inadequate distribution of gravity loads, which could lead to cracking or buckling.

Where masonry construction is required to provide fire resistance, this is to limit the probability of compromised fire resistance of the assembly, which could lead to harm to persons.
