Can you plan decompression dives for SCUBA?

• A. Yes, for all divers
• B. No, decompression dives are never allowed
• C. Decompression dives may be planned only when absolutely necessary and signed off by the CO
• D. Only with medical clearance

Answer: (C)

Decompression dives carry significant risk and require careful, mission-specific planning. They are only undertaken when a dive profile truly cannot be accomplished without decompressing, and there must be formal authorization that accepts the risks and allocates the necessary safety resources. In this context, the plan is valid only when the commanding officer signs off, confirming that the mission justifies the risk and that procedures, safety gear, medical support, and contingencies are in place. That overview explains why this is the best answer: decompression planning isn’t something a diver can do universally or without high-level approval. Medical clearance is important for health, but it doesn’t replace the need for command authorization and mission risk acceptance.
