What is the required occupant load for a building to need four exits according to PD 1096?

The requirement for a building to have four exits, according to PD 1096, is based on the occupant load determined by the size and intended use of the building. When the occupant load reaches 1000 or more individuals, it presents a significant challenge for safe evacuation during emergencies. Therefore, having four exits is mandated to ensure that people can exit safely and efficiently in the event of an emergency, distributing the egress capacity more effectively.

This requirement is intended to minimize the risk of overcrowding at any single exit and to facilitate a quick and organized evacuation for larger groups of occupants. Buildings with lower occupant loads do not necessitate as many exits, as fewer people can be more easily accommodated within a smaller number of exits.
