Question 1407 Deck Safety

The correct answer is B) An air tank will provide about ten minutes of air for the survivors and the engine. In a totally enclosed lifeboat enveloped in flames, the air tank is designed to provide a limited supply of breathable air for the survivors and the lifeboat's engine. This ensures the boat can operate and maintain a safe environment for a short period of time until the flames are extinguished or the lifeboat can be launched to safety. The other options are incorrect because: A) a manual water spray system is not a standard feature of totally enclosed lifeboats, C) the ventilators would not automatically close in a fire scenario, and D) the lifeboat's engine does not draw air from outside the boat, which could lead to asphyxiation.
