Intent | Intent 1: To limit the probability that loadbearing walls,
columns and arches exposed to fire will prematurely fail or collapse,
which could lead to the failure or collapse of supported floor or
roof assemblies during the time required to achieve occupant safety
and for emergency responders to perform their duties, which could
lead to damage to the building. Intent 2: To limit the probability that floor or roof assemblies
exposed to fire will prematurely fail or collapse during the time
required to achieve occupant safety and for emergency responders to
perform their duties, which could lead to damage to the building.
Intent 3: To limit the probability that loadbearing walls,
columns and arches exposed to fire will prematurely fail or collapse,
which could lead to the failure or collapse of supported floor assemblies,
which could lead to the spread of fire from a lower storey of a building
to an upper storey or to the exterior during the time required to
achieve occupant safety and for emergency responders to perform their
duties, which could lead to damage to the building. Intent 4: To limit the probability that floor or roof assemblies
exposed to fire will prematurely fail or collapse, which could lead
to the spread of fire from a lower storey of a building to an upper
storey or to the exterior of the building during the time required
to achieve occupant safety and for emergency responders to perform
their duties, which could lead to damage to the building.
Intent 5: To limit the probability that, in the event of a
fire, the absence of fire suppression systems within a storey will
lead to the growth of fire, which could lead to the spread of fire
within the storey during the time required to achieve occupant safety
and for emergency responders to perform their duties, which could
lead to damage to the building. |
