Question 917 Deck General

The correct answer is B) Preventing the asphyxiation of personnel below decks. The primary safety consideration when loading or discharging vehicles on a Ro-Ro (roll-on/roll-off) vessel is the potential for the accumulation of hazardous exhaust gases in enclosed or poorly ventilated spaces below deck. Vehicle engines release carbon monoxide and other toxic fumes that can quickly build up to dangerous levels, posing a serious asphyxiation risk to any personnel working in those areas. Proper ventilation and gas monitoring are crucial to protect the crew during these operations. The other answer choices are not the most important safety consideration in this scenario. Ensuring fuel barges cannot come alongside is not directly related to the vehicle loading/discharging process. Notifying the engine room or calling out the deck department are secondary actions, whereas preventing asphyxiation is the primary safety priority.
