If there is an imminent danger of collapse, what action should be taken?

• A. Document and monitor
• B. Schedule a routine inspection
• C. Escalate to emergency actions
• D. Ignore until the next inspection

Answer: (C)

Imminent danger requires immediate action to protect lives and public safety. Escalating to emergency actions means activating the emergency action plan, stopping nonessential work, securing and isolating the area, evacuating as needed, and notifying the appropriate authorities and the bridge owner or agency. This rapid response addresses the hazard now and allows trained personnel to assess and stabilize or repair the structure. Documenting and monitoring or scheduling a routine inspection won’t remove the immediate risk, and ignoring it until the next inspection could lead to a collapse or injuries.
