Intent 1:
To limit the probability that smoke will migrate
from a floor area into exit stairs in a fire situation, which could
lead to the buildup of smoke in the exit stairs, which could lead
to:
- delays or inefficiencies in fire 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, including emergency
responders.
