Which element must a Permit to Dive contain?

• A. Dive profile, risk assessment, controls, permitted tasks, and emergency procedures.
• B. The diver's personal logbook.
• C. Weather data from last season.
• D. Vessel registration number.

Answer: (A)

The main idea being tested is that a Permit to Dive must formally outline how the underwater work will be conducted to keep it safe. The best answer includes the dive profile, risk assessment, controls, permitted tasks, and emergency procedures. This combination ensures the dive supervisor can plan the operation with a clear depth, bottom time, entry and exit methods, and gas/decompression plan; identify hazards and how they’re mitigated; specify exactly what tasks are authorized under the permit; and lay out steps to take if something goes wrong, including who to contact and how to respond quickly. The other items don’t fit because a diver’s personal logbook is a separate record of experience, not part of the approval and safety plan; weather data from last season is outdated for planning a current dive and not a required component of the permit itself; and a vessel registration number is administrative information unrelated to the safety and scope of the dive work.
