Intent 1:

To exempt guards protecting fire escape platforms, balconies and stairways from the requirements of Sentence 3.4.6.6.(2) and permit a lower minimum guard height, on the basis that the fire escapes will be used infrequently.

This [the minimum guard height] is to limit the probability that:

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