Question 1947Deck General70% to pass
On small passenger vessels, all spaces containing gasoline-powered machinery or gasoline storage tanks must be ventilated with _______________.
AI Explanation
The correct answer is A) natural air supply and mechanical exhaust fans.
The reason this is the correct answer is that under U.S. Coast Guard regulations, all spaces containing gasoline-powered machinery or gasoline storage tanks on small passenger vessels must be ventilated with a natural air supply and mechanical exhaust fans. This ensures that any flammable vapors from the gasoline are properly removed from the space, reducing the risk of fire or explosion.
The other answer choices are incorrect because B) does not use mechanical exhaust, C) refers to ventilation for foul weather rather than normal operation, and D) uses air conditioning which is not a requirement for this type of ventilation system.
