What should be done during trench rescue operations?

• A. Enter the trench to begin rescue immediately.
• B. Ensure the trench lip is safe, secure the rescue area, and secure the trench.
• C. Use only heavy equipment to lift casualties.
• D. Evacuate civilians first.

Answer: (B)

Safety and scene control are the priorities in trench rescue. The first steps are to prevent further collapse and create a safe environment for rescuers and victims. Checking the trench lip for stability addresses the most vulnerable point—the edge that can fail suddenly and pull the trench in. Securing the rescue area sets up a controlled zone, keeps bystanders away, and ensures communications, lighting, and access are managed. Securing the trench itself means applying shoring, trench boxes, or other stabilization as needed and establishing a safe entry/egress path.

Entering the trench or trying to lift casualties without these protections can trigger a collapse and put everyone at greater risk. Heavy equipment has its place, but it should be used within a stabilized, controlled environment rather than as a substitute for trench protection. Civilians should be moved to safety, but the immediate focus is on making the scene safe and ready for rescue efforts.
