3.2.7.9.(1)

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, 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.
