Level 3 survivability requires which of the following?

Level 3 survivability requires which of the following?

• A. A fully sprinklered building
• B. A central backup generator
• C. Two independent FCCs
• D. A fire-rated elevator shaft

Answer: (A)

Sprinkler protection directly limits how large and intense a fire can get, which is the main factor in Level 3 survivability. When a building is fully sprinklered, heat, flames, and smoke are kept under control at the source, helping to keep exit routes usable and critical safety systems—like alarms and communications—operating longer during a fire. This automatic fire suppression creates a safer environment for occupants and gives responders a more controllable situation, which is the essence of Level 3 survivability. Backup power, independent command centers, or a fire-rated elevator shaft contribute to safety in important ways, but they don’t by themselves guarantee the level of survivability that comes from reducing fire growth and spread throughout the building. Sprinklers address the core risk that threatens survivability in a fire scenario—the fire itself—much more directly.
