In Group A-4 occupancies, an automatic sprinkler system must be installed if the occupant load exceeds which number?

In Group A-4 occupancies, which typically include assembly spaces with limited duration such as arenas and theaters, the requirement for an automatic sprinkler system is based on the potential occupant load. When the occupant load exceeds 300, it triggers the necessity for an automatic sprinkler system as a safety measure to provide adequate fire protection and evacuation capability.

This requirement reflects the increased risk associated with larger gatherings of people, where the potential for emergencies is heightened, and rapid egress may become critical. Sprinkler systems play a vital role in controlling fire spread, protecting both occupants and property. Thus, having a threshold of 300 occupants ensures that buildings can adequately safeguard a larger number of individuals in the event of a fire hazard.
