Which item best represents a comprehensive emergency plan?

• A. Evacuation routes only.
• B. A list of emergency phone numbers only.
• C. First aid materials and basic equipment only.
• D. Rescue procedures, evacuation routes, access to hyperbaric treatment, first aid equipment and trained personnel, and triggering criteria.

Answer: (D)

In diving emergencies, you need a plan that covers every step from recognizing a problem to delivering definitive medical care, with clear roles, resources, and conditions for action. The best option combines rescue procedures, evacuation routes, access to hyperbaric treatment, first aid equipment and trained personnel, and triggering criteria into one ready-to-activate plan. Each piece is essential: rescue procedures define how to locate and recover an distressed diver; evacuation routes ensure safe, rapid transfer to a location where care can be provided; access to hyperbaric treatment is critical for decompression illness and other dive-related injuries; having the right first aid gear and trained personnel means care can begin immediately; triggering criteria specify exactly when to initiate the plan and who takes charge, preventing hesitation or miscommunication.

If you only have evacuation routes, you’re missing medical response and activation steps. If you only have emergency numbers, there’s no actionable roadmap for rescue and treatment. If you have first aid materials but no trained responders or activation criteria, delays and confusion can still occur. A single, integrated plan that includes all these elements ensures a coordinated, timely, and effective response to a diving emergency.
