Question 1 of 27070

Prior to boarding from a MODU, a davit-launched liferaft should be well ventilated of excess __________.

🔍 Key Concepts

• Davit-launched liferafts on MODUs and how they are boarded • The type of gas that is commonly used in liferaft inflation cylinders • Why some gases can be dangerous if trapped in a confined survival craft

💭 Think About

• Think about what gas is stored under pressure to rapidly inflate a liferaft and which of these options is most commonly used for that purpose. • Consider which of the listed gases would realistically be present in significant quantity inside a newly-inflated liferaft. • Ask yourself which gas, if present in high concentration, would most directly affect breathing and consciousness for people boarding the raft.

✅ Before You Answer

• Identify which of the four gases is standard for liferaft inflation systems per common lifesaving appliance practice. • Eliminate any gases that are unlikely to be present in a liferaft or are typically associated with other machinery or systems (like refrigerants or exhaust). • Focus on the gas that, when released from cylinders during inflation, could temporarily displace oxygen inside the raft until it is ventilated.
