Intent 1:
To limit the probability that, during a failure
of the normal power supply in a fire emergency situation, emergency
generator power supplies to certain building services will not be
capable of performing their intended functions for a length of time
sufficient for emergency responders to carry out their duties, which
could lead to:
- the inability of elevator systems to be used in emergency
response operations, which could lead to delays in emergency response
operations,
- firefighting operations being ineffective, which could
lead to the fire not being controlled or suppressed,
- the inability of ventilation systems to provide the
minimum level of air supply in areas of refuge, and
- the inability of smoke management systems to control
smoke conditions, which could lead to delays in emergency response
operations.
This is to limit the probability of
the spread of fire, which could lead to damage to the building.
