1. OS3


OS3 Safety in Use



Intent 1:

To supersede the requirements of Sentence and require a greater minimum height for guards for exterior exit stairs and landings that are more than 10 m above ground level, on the basis that additional protection from falling over the guards is warranted.

This is to limit the probability that:

  • persons using exit ramps and landings will fall over a guard from a higher level to a lower level, which could lead to harm to persons, and
  • the absence of a high guard for exit ramps and landings will impede its use during an emergency situation, which could lead to lead to delays in the evacuation or movement of persons to a safe place, which could lead to harm to persons.
