Which statement best describes the purpose of a passive fire protection strategy?

• A. To determine the building's color scheme
• B. To resist fire through building materials and design without active systems
• C. To use sprinklers and alarms to control fires
• D. To monitor structural health after a fire

Answer: (B)

Passive fire protection relies on the building’s own structure and construction to resist and slow fire without relying on powered or active systems. It aims to contain the fire, limit its spread between compartments, and protect structural elements so occupants can evacuate and firefighters can respond safely. This is achieved through fire-resistant materials and assemblies (like rated walls, floors, and ceilings), proper compartmentation, fire doors, and firestopping around penetrations. In contrast, active fire protection uses systems that require action or energy, such as sprinklers and alarms, which is not the focus of passive protection. Monitoring or assessing a building after a fire doesn’t prevent fire growth and isn’t part of passive protection either.
