Question 1933 Deck General
70% to passA gasoline fuel tank vent on a small passenger vessel should terminate _______________.
A
Midway between the fuel tank and the engine
B
On the hull exterior as high above the waterline as practicable and remote from any hull opening
C
As close to the deck plates as possible
D
Below the waterline to eliminate the accumulation of explosive vapors
AI Explanation
The correct answer is B) On the hull exterior as high above the waterline as practicable and remote from any hull opening. The reasoning for this is that the fuel tank vent should terminate in a location that helps dissipate any explosive gasoline vapors and prevents them from accumulating in enclosed spaces. Terminating the vent high above the waterline and away from hull openings allows the vapors to safely vent to the atmosphere, reducing the risk of explosions or fires. The other options, such as venting close to the engine or below the waterline, do not adequately address the need to properly vent explosive vapors.
