Intent 1:
To exempt elevator hoistways from the application
of Sentence 3.2.6.6.(1).
This is to limit
the probability that the use of elevator hoistways for venting floor
areas will lead to exposure of persons in the elevator cars to smoke,
or the spread of smoke to other parts of the building, which could
lead to:
- harm to persons, including emergency responders, in
elevator cars, and
- delays or inefficiencies in fire emergency response
operations, which could lead to:
- delays in evacuation or moving to a safe place, which
could lead to harm to persons, including emergency responders, and
- the spread of fire to other parts of the building, which
could lead to harm to persons, including emergency responders.
