OS1 Fire Safety

Attribution

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

Intent

Intent 1:

To limit the probability of an inability to resist expected gravity and lateral loads, which could lead to:

  • the inadequate distribution of vertical loads to and from studs, which could lead to the excessive deflection or failure of wall plates,
  • inadequate diaphragm action of plates, which could lead to the excessive deflection of walls, or
  • inadequate lateral support of the ends of studs.

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.
