What practical steps can be taken to mitigate entanglement and marine life hazards during operations?

• A. Ignore potential hazards if visibility is good.
• B. Survey area for hazards, avoid protruding equipment, maintain safe distances from marine life, and use protective PPE.
• C. Rely on crew training alone without area survey.
• D. Use only PPE and ignore area survey.

Answer: (B)

Mitigating entanglement and marine life hazards relies on a proactive approach: assess the area for hazards and wildlife, manage equipment to avoid snag points, keep safe distances from marine life, and wear protective gear. Surveying the work area ahead of and during operations helps you spot potential entanglement sources such as protruding hardware, unsecured lines, and gear that could catch on reefs or nets, as well as any presence of marine life that might be stressed or attracted to the activity. By avoiding protruding equipment, you reduce the chances of lines or gear catching on obstacles or divers, which is a common route to entanglement. Maintaining safe distances from marine life protects both divers and animals, minimizes disturbance, and lowers the risk of accidental contact. Wearing appropriate protective PPE provides a first line of defense if contact occurs or if equipment shifts, with gloves and protective clothing reducing cuts and abrasions and eye or face protection guarding against debris or splashes.

Relying on good visibility alone is insufficient because hazards can be hidden below or behind structures, and wildlife behavior can change quickly. Training without a pre-operation area survey misses real-world conditions you’ll face, and PPE by itself cannot prevent entanglement from occurring if lines are unsecured or equipment is left in protruding positions.
