Intent

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.
