Intent 1:
To limit the probability that smoke and heat from
a fire in a storey adjacent to a floor opening will migrate into the
interconnected floor space and bypass sprinklers and smoke detectors
without actuating them, which could lead to:
- the fire not being controlled or suppressed, which could
lead to the spread of fire, and
- emergency responders not being promptly notified of
the fire situation, which could lead to delays or inefficiencies in
carrying out fire emergency response operations, which could lead
to the spread of fire.
This is to limit the probability of
damage to the building.
