Which statement best describes passive fire protection?

• A. It relies on building materials and construction to resist fire.
• B. It relies on detecting fires and activating alarms.
• C. It requires active human intervention to suppress fires.
• D. It involves sprinklers and water flow.

Answer: (A)

Passive fire protection relies on the building’s fabric to resist fire without needing power or human action. It uses fire-resistant materials and construction practices—such as rated walls, floors, and doors, fire-stopped joints, and compartmentalization—to slow the growth and spread of fire and to help keep structural integrity long enough for occupants to escape. The purpose is to provide inherent protection built into the structure itself, not to rely on sensors or automatic or manual interventions. In contrast, detecting fires and triggering alarms is an active measure that signals a fire but does not by itself keep the fire from spreading. Sprinklers and water flow are also active protection, requiring a water supply and system activation to suppress the fire. So, the statement that best describes passive fire protection is the one that emphasizes protection provided by building materials and construction designed to resist fire.
