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.
