OS3 Safety in Use

Attribution

[F20,F22-OS3.1]Applies to floors and elements that support floors.
[F20,F22-OS3.7]Applies to walls, and elements that support walls, that contain doors or windows required for emergency egress.

Intent

Intent 1:

To limit the probability of an inability to resist expected gravity loads, which could lead to beams or their supports being crushed.

This is to limit the probability of:

  • compromised structural integrity,
  • where elements support or are part of an environmental separator, the failure of required environmental separation elements, which could lead to deterioration, or
  • an inability to resist expected loads, which could lead to:
    • the excessive deflection or vibration of floors, or
    • the excessive movement or deformation of walls.

This is to limit the probability of:

  • for floors and elements that support floors, persons losing their balance, tripping or falling, or
  • the compromised operation of doors or windows required for egress in an emergency.

This is to limit the probability of harm to persons.
