Who is primarily responsible for guaranteeing emergency equipment is ready and functional?

• A. Diver
• B. Client
• C. Vessel captain
• D. Dive Supervisor

Answer: (D)

The Dive Supervisor is the on-site safety lead for the dive operation, so they are the person charged with making sure emergency equipment is ready and functional. They oversee pre-dive checks and ongoing readiness of all emergency gear—oxygen systems and regulators, first aid and resuscitation equipment, emergency signaling devices, spare air, and any backup safety lines—ensuring it’s present, accessible, within service intervals, and tested. They also verify that the team knows how to use the gear and can respond quickly in an emergency, including conducting drills. The vessel captain handles ship operations and general safety of the operation, while divers rely on their own equipment, but the Dive Supervisor holds the responsibility for the emergency response readiness that directly affects the dive safety.
