Question 1719Deck General70% to pass
On board small passenger vessels, ducts for compartments which contain gasoline powered machinery or gasoline storage tanks _______________.
AI Explanation
The correct answer is D) All of the above.
This is because the regulations for ducts on small passenger vessels with gasoline-powered machinery or storage tanks require that:
1) The ducts must not allow any appreciable vapor flow except through their normal openings, to prevent the spread of fire or explosion.
2) The ducts must be of rigid, permanent construction to maintain their integrity and function.
3) The ducts must lead as directly as possible and be properly fastened and supported, to ensure efficient ventilation and prevent leaks or blockages.
The other answer choices only partially describe the regulatory requirements, whereas D) covers all the necessary specifications for these critical ventilation ducts on small passenger vessels with gasoline systems.
