This is from Ontario Building Code Division B Part 9:
_____________________________________________________________________________________________________________________________
9.9.4.2. Fire Separation for Exits
(1) Except as provided in Sentence (5) and Article 9.9.8.5., every exit other than an exit doorway shall be separated
from each adjacent floor area or from another exit by a fire separation having a fire-resistance rating not less than that
required for the floor assembly above the floor area.
(2) Where there is no floor assembly above, the fire-resistance rating required in Sentence (1) shall not be less than that
required by Subsection 9.10.8. for the floor assembly below, but in no case shall the fire-resistance rating be less than
45 min.
_____________________________________________________________________________________________________________________________
Is an exit doorway a part of an exit? Would an exit doorway be connected to any adjacent floor area? ( I think there is no scenario where an exit doorway would be connected to any adjacent floor area, please confirm.)
