Question 185Safety & Environmental - Assistant Engineer

The correct answer is D. A pressurized air tank will provide approximately ten minutes of air for the survivors and the diesel engine. This is the correct answer because totally enclosed lifeboats are designed to provide a temporary refuge for the crew in the event of a fire. The pressurized air tank is a critical safety feature that supplies breathable air to the lifeboat's interior, allowing the crew to survive until they can be rescued or the fire is extinguished. The other options are incorrect because they do not accurately describe the safety features of a totally enclosed lifeboat. The ventilators do not automatically close, the diesel engine does not take air from outside the lifeboat, and there is no high-volume manual pump for a water spray system.
