Which action is required if a diver loses uniform communications?

• A. Switch to hand signals only.
• B. Switch to alternative communication methods per the contingency plan and continue with rescue procedures.
• C. Attempt to repair the helmet telecommunication system immediately.
• D. Abort the dive and return to routine operations.

Answer: (B)

When primary communications fail underwater, you rely on the plan you’ve trained for: bring in the backup methods and keep the operation moving toward safety. Switching to alternative communication methods outlined in the contingency plan ensures that the diver and the surface team stay coordinated, share critical information (air status, depth, location), and can guide a rescue if needed. This keeps the dive safe rather than waiting on a repair that may take time and leave people without guidance.

Attempting to repair the helmet system right away can introduce delays and risk losing track of the situation, while aborting the dive isn’t necessary if the contingency plan can be executed. Using the backup communications and continuing rescue procedures is the appropriate, safety-focused response.
