Intent 1:
To limit the probability that inadequate air movement
through vestibules will go unnoticed, which could lead to the smoke
control system not operating as originally intended in a fire situation,
which could lead to the buildup of smoke in exit stair shafts, which
could lead to:
- delays or inefficiencies in emergency suppression operations,
which could lead to the spread of fire, which could lead to harm to
persons, including emergency responders, and
- delays in the evacuation or movement of persons to a
safe place, which could lead to harm to persons.
