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, or
for persons to evacuate or move to a safe place, 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, which could lead to delays in the evacuation or movement
of persons to a safe place,
- firefighting operations being ineffective, which could
lead to the fire not being controlled or suppressed, which could lead
to the spread of fire,
- 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, which could lead to delays in the evacuation or movement
of persons to a safe place.
This is to limit the probability of
harm to persons, including emergency responders.
