What term describes the designated area to prevent firefighters from being caught in a collapse?

• A. Collapse zone
• B. Safe zone
• C. Exclusion zone
• D. Exfiltration zone

Answer: (A)

During structural firefighting, identifying where debris could travel if the building collapses is essential for crew safety. That designated area is the collapse zone—the space outside the structure where falling or collapsing materials could reach, so crews stay clear and perimeters are maintained to prevent entrapment or injury.

This term is specifically about the risk from a collapse, which is why it’s the best choice. A safe zone is a general term for a safe area but doesn’t imply the specific danger of collapse. An exclusion zone is a broader hazard-control area and not the term used for the collapse-specific protection area. An exfiltration zone refers to exiting the scene, not to where debris might fall.
