Question 3347 Deck General

The correct answer is A) carbon dioxide gas. Prior to boarding a liferaft, it should be well ventilated to remove excess carbon dioxide gas. This is because the liferaft's enclosed space can accumulate carbon dioxide from the breathing of the occupants, which can be hazardous. Ventilation helps to maintain a safe and breathable atmosphere inside the liferaft. The other options, such as hydrocarbon gas, carbon monoxide gas, or freon gas, are not the primary concerns for a liferaft prior to boarding from a MODU (Mobile Offshore Drilling Unit).
