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 aligned joints, which could lead to inadequate strength, which could lead to an inability to resist expected gravity and lateral loads, which could lead to the excessive deflection of sheathing between roof framing members, which could lead to damage to roofing.

Where assemblies are 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.
