Intent 1:
To limit the probability that smoke will build up
in the exit stairs in a fire situation during the time required to
achieve occupant safety and for emergency responders to perform their
duties, 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 evacuation or moving to a safe place, which
could lead to harm to persons.
