Intent 1:
To limit the probability of migration of contaminated
air from a building to another during a fire, which could lead to
exposure to smoke, 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.
