9.15.5.1.(1)

Objective

OS3 Safety in Use

Attribution

[F20,F40,F61-OS3.1]Applies to floors and elements that support floors.

Intent

Intent 1:

To limit the probability of:

  • an inadequate distribution of roof or floor loads transmitted through framing elements, which could lead to overstressing of hollow masonry units,
  • an inadequate barrier, which could lead to termites accessing structural wood elements, or
  • the ingress of water into the cores of hollow masonry units.

This is to limit the probability of:

  • compromised structural integrity, or
  • where elements support or are part of an environmental separator, the displacement or failure of required environmental separation elements, which could lead to the deterioration of building elements.

For floors and elements supporting floors, this is to limit the probability of excessive deflection, which could lead to persons tripping or falling, which could lead to harm to persons.
