For which type of occupancy is a supervised sprinkler system mandatory?

A supervised sprinkler system is a requirement particularly in assembly occupancies when the occupant load exceeds 300 people. The rationale behind this requirement is rooted in life safety and fire protection principles. Assembly occupancies are spaces designed for large groups of people to gather, such as theaters, concert halls, or sports arenas. The presence of a higher number of occupants increases the risk in case of a fire, making it essential to have more robust fire suppression systems in place.

A supervised sprinkler system not only helps in the immediate detection and control of fire but also aids in ensuring a quicker response from fire services since the system can alert them automatically. This level of protection is deemed necessary to safeguard the lives of the occupants and minimize fire-related damages in crowded environments.

Other types of occupancies mentioned, while they may have specific fire safety requirements, do not universally mandate supervised sprinkler systems to the same extent as high-occupancy assembly venues do.
