What should be included in a pre-dive hazard identification for an offshore dive site?

• A. Potential hazards: entanglement, entrapment, gas contamination, electrical hazards, underwater hazards, weather, current, poor visibility
• B. Weather only
• C. Gas contamination only
• D. All hazards reserved for later

Answer: (A)

In offshore diving, you identify hazards before the dive to anticipate the range of risks you might face at the site. The best approach is to consider environmental conditions (weather, current, visibility) alongside site-specific and equipment-related hazards. This includes potential entanglement or entrapment from nets, lines, or rig structures; underwater hazards such as sharp edges, entangled gear, or overhead configurations; gas-related risks like contamination or issues with the gas supply; and electrical hazards or other equipment-related dangers found on offshore installations. By listing these hazards, you can put in place controls and planning—pre-dive checks, gas testing, equipment readiness, clear communication and bailout procedures, standby support, and defined entry/exit and emergency plans—so the team is prepared for conditions that could change during the dive. The other options are too narrow, neglecting the breadth of risks offshore environments present, or imply hazards can wait until later, which isn’t safe practice.
