OS1 Fire Safety



Intent 1:

To limit the probability that smoke will build up in [exit] stairways 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.
