Your examiner asks: "What precautions should be taken before personnel work on a RoRo cargo deck during loading/unloading?"

A. Ensure all personnel have completed RoRo-deck-specific familiarisation/training (vehicle movement hazards, blind spots, lashing point hazards, exhaust fume/CO risk from running vehicle engines in an enclosed deck space), enforce high-visibility PPE and defined pedestrian routes/exclusion zones from vehicle movement areas, and maintain clear communication between the deck team and vehicle marshals/drivers throughout the operation.

B. No specific precautions beyond standard PPE are needed, since RoRo deck hazards are identical to any other open deck working area.

C. RoRo deck safety is solely the stevedoring contractor's responsibility, with no familiarisation obligation on ship's crew working in the same space.

D. Exhaust fume risk is not a genuine RoRo deck hazard since vehicle decks are always naturally ventilated to atmosphere.
