What steps should be taken if a structure shows signs of imminent collapse?

• A. Immediately withdraw to a safe distance, establish a collapse zone, call for additional resources, and adjust operations accordingly.
• B. Continue interior operations with caution.
• C. Ignore signs; continue as planned.
• D. Only call for more resources after a confirmed collapse.

Answer: (A)

When signs point to imminent structural failure, the priority is to protect people by getting them out of danger and keeping others away from the hazard. The best approach is to withdraw to a safe distance, establish a collapse zone to prevent entry into the danger area, call for additional resources specialized for collapse scenarios, and adjust operations to reduce exposure—ceasing risky interior actions and reconfiguring the plan as needed. This sequence minimizes the chance of entrapment and allows a qualified response team to assess and stabilize the structure from a safer position. Continuing interior operations under this threat greatly increases the risk of being crushed or buried if the structure collapses. Waiting for a confirmed collapse before calling for more resources wastes precious time and leaves responders without the help they need to manage the danger effectively, which is why those options are not appropriate.
