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 means to anchor wall assemblies at openings, or inadequate means for the top and bottom attachment of cladding, sheathing or interior finish materials, which could lead to:

  • misaligned top and bottom ends of studs, or
  • the displacement of studs.

For assemblies that are required to provide fire resistance, this is to limit the probability of excessive movement, deformation or failure under expected loads, which could lead to compromised fire resistance of the assemblies, which could lead to harm to persons.
