Survivability requirements apply to systems using complete (total) evacuation.

• A. True
• B. False
• C. Sometimes
• D. Never

Answer: (B)

Survivability requirements focus on keeping essential life-safety systems operating during a fire or power loss so people can be warned, find exits, and responders can work. These requirements apply to critical systems like fire alarm signaling, emergency communications, emergency lighting, and the power supplies that keep them running, for a defined period under adverse conditions. They are not tied to a single evacuation method; whether a building uses total evacuation or a staged approach, the safety systems must remain functional to support safe egress. So the idea that survivability requirements only apply to complete evacuation isn’t accurate—the requirements cover vital life-safety functions regardless of the evacuation strategy.
