Passive fire protection strategies are designed to function without which of the following?

• A. Emergency exits
• B. Active systems such as alarms and sprinklers
• C. Structural damage
• D. Human intervention

Answer: (B)

Passive fire protection relies on the building’s own construction to resist fire and contain its spread, without needing any action from alarms, sprinklers, or other active systems. It uses fire-rated walls, floors, doors, and joints, along with proper compartmentalization and detailing, to slow heat and flame, protect structural elements, and keep escape routes open long enough for people to evacuate. Because of this built-in, non-action-dependent nature, it can function even if detection or suppression systems aren’t operating. Emergency exits are essential for safe evacuation, but the protective barriers work independently of those exits. Human intervention isn’t required for the protection to perform, since it’s designed to act automatically through its fire-resistive design.
