70% to passWhy is it necessary to extend ventilators of gasoline powered vessels to the bilges?
A
To remove fuel vapors which are heavier than air
B
To cool the machinery areas
C
To keep them dry, and thus easier to clean
D
To provide adequate air to the engines
AI Explanation
The correct answer is A) To remove fuel vapors which are heavier than air. Gasoline vapors are heavier than air and tend to settle in the bilges of vessels. Extending the ventilators to the bilges helps remove these flammable vapors, reducing the risk of fire or explosion. This is a critical safety requirement for gasoline-powered vessels, as specified in Coast Guard regulations. The other options are incorrect because: B) Cooling machinery is not the primary purpose, C) Keeping the ventilators dry is not the main reason, and D) Providing air to the engines is not the main function of bilge ventilation on gasoline-powered vessels.
