According to fire safety regulations, what is required for existing high-rise structures over 150 feet?

In high-rise structures that exceed 150 feet, one of the key requirements is the installation of a public address system. This system serves a critical role in communicating important safety information to building occupants during emergency situations, such as fires. It allows for rapid dissemination of instructions, updates on the situation, and emergency announcements that can guide tenants in evacuation or provide reassurance during a crisis.

The presence of a public address system is vital in these tall buildings, where challenges such as height can complicate evacuation efforts and increase the difficulty of ensuring that all occupants are informed and aware of the actions they should take. In contrast, while other options like automatic sprinklers, regular fire drills, and dedicated fire exits are important safety features, they are not specifically mandated as requirements for all existing high-rise structures over 150 feet in the same way that a public address system is recognized for its immediate effectiveness in emergencies.
