The hazard changes with the operation

The drum is not the only moving part: cables, nets and other gear also travel across the deck. An apparently slack line can suddenly tighten. Wet surfaces and vessel movement make it harder to stay balanced beside drawing-in and trapping points.

Review shooting, hauling, stowing and dealing with faults separately. A safe position for one operation may lie within the gear’s path during another. Include people assisting or crossing the deck, as well as the person operating the machinery controls.

Separate crew from moving equipment

Machine guards should prevent dangerous contact without introducing new snagging points. Published designs for particular winch models are not universal solutions: adaptation, strength, access and compatibility require technical assessment of the equipment actually installed on board.

Reducing the need to guide cable manually beside the drum is a design decision. Close-fitting clothing and deck housekeeping help, but do not compensate for an accessible rotating component. Provide routes that avoid crossing lines and areas where gear is being gathered.

Controls that work during an emergency

Check that exposed people can reach a suitable control and that everyone understands its purpose. An auxiliary power-disconnection switch must not be assumed equivalent to every emergency-stop system: understand the actual stopping behaviour and any energy that remains afterwards.

Do not defeat pedals or hold-to-run functions. Before restarting, establish where crew members are and whether the machinery is safe. Resolve unclear signals or an obscured operating area before resuming, rather than relying on an assumption that everyone has moved away.

Maintenance and onboard contingencies

Corrosion, wear and deterioration of brakes, controls or cables require inspections suited to marine service. A jam does not justify reaching into the mechanism: follow the equipment-specific isolation and energy-control procedure before any authorised intervention takes place.

Agree signals, stop responsibilities and the response to entanglement or snagged fishing gear. Snagging can also affect vessel stability. Training and emergency arrangements must reflect the particular vessel and its available resources, without depending on improvised actions by crew members.
