What must a dive supervisor verify before authorizing a dive?

• A. Weather Conditions and Sea State
• B. Diver Medical History and Licenses
• C. Incident Reports from Prior Dives
• D. Dive Plan, Equipment Checks, and Safety Procedures

Answer: (D)

Ensuring readiness before authorizing a dive means confirming a solid dive plan, verified equipment, and established safety procedures. The dive plan should outline the dive objectives, planned depth and duration, entry and exit procedures, gas management, and clear contingency actions. This shows there is a well-thought-out approach and a path to handle potential problems.

Equipment checks verify that all gear is functional, properly maintained, and ready for use. This includes redundant gas supply if required, communication systems, valves, cylinders, gauges, and any specialty equipment. Safe operation depends on every piece working as intended, with any issues addressed before entering the water.

Safety procedures ensure everyone knows how to respond to emergencies, including signaling, buddy procedures, abort criteria, and the rescue and medical plans. Clear roles and rehearsed responses reduce reaction time and confusion if something goes wrong.

Weather conditions and sea state, while important for overall planning, and diver medical history or licenses, or incident reports from prior dives, influence risk assessment and candidate suitability, but authorization hinges on having a complete, practiced plan with functioning equipment and agreed-upon safety procedures.
