Who has the authority to abort a dive for safety reasons?

• A. The Diver
• B. The On-Site Safety Officer
• C. The Dive Supervisor
• D. The Client Representative

Answer: (C)

The Dive Supervisor has the authority to abort a dive for safety reasons. They’re responsible for the overall safety of the dive operation, including assessing conditions, equipment, gas, and procedures. If any factor suggests risk—poor visibility, equipment failure, gas issues, adverse weather, or dangerous procedures—the Dive Supervisor can suspend or abort the dive to protect everyone involved. The On-Site Safety Officer can raise concerns and support safety decisions, but the final call rests with the Dive Supervisor to ensure a coordinated and safe shutdown. Divers can opt to stop their own activity if they feel unsafe, but formal abort authority lies with the Dive Supervisor to maintain control of the operation. The Client Representative does not have authority to halt the dive for safety reasons.
