OS1 Fire Safety



Intent 1:

To limit the probability that a fire that has spread into a lobby from an adjacent floor area will lead to untenable conditions in the exit, which could lead to delays in the evacuation or movement of persons to a safe place, which could lead to harm to persons.

Intent 2:

To supersede the requirements of Sentence, which would otherwise require the exit to be separated from adjacent floor areas by a fire separation having a minimum fire-resistance rating.
