Intent 1:
To supersede the requirements of Sentence 3.4.6.16.(1), which would otherwise require doors to be readily
openable, and permit exit and egress doors in certain floor areas
to be locked if certain conditions are met [the exit and egress doors
comply with Sentences 3.4.6.17.(2) to (9)].
This is to limit the probability that:
- the public will be locked in the floor area, which could
lead to delays in the evacuation or movement of persons to a safe
place in an emergency situation, which could lead to harm to the public,
- egress and exit doors will not be readily openable in
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,
- persons will not be familiar with the location of emergency
exits, which could lead to delays in the evacuation or movement of
persons to a safe place in an emergency situation, which could lead
to harm to persons, and
- travel distances to an exit door will be excessive,
which could lead to delays in the evacuation or movement of persons
to a safe place in an emergency situation, which could lead to harm
to persons.
Intent 2:
To state the application of Sentences 3.4.6.17.(2) to (9).
