Intent 1:
To supersede the requirements of Subsections 3.1.8., 3.1.9. and 3.2.8., which would otherwise permit openings in exit
fire separations, and limit the openings to only certain penetrations,
on the basis of maintaining the integrity of exits.
This is to limit the probability that:
- fire will spread into an exit, which could lead to delays
in the evacuation or movement of persons to a safe place, which could
lead to harm to persons,
- fire will spread into an exit, which could lead to emergency
responders being delayed in gaining access to floor areas, which could
lead to delays or ineffectiveness in fire emergency response operations,
which could lead to:
- delays in the evacuation or movement of persons to a
safe place, which could lead to harm to persons including emergency
responders, and
- the spread of fire to other parts of the building, which
could lead to harm to persons, and
- fire will spread from one floor area to another floor
area by means of an exit, which could lead to harm to persons in the
other floor area.
