Question 1735 Deck General

The correct answer is D) All of the above. The regulations for small passenger vessels require that the gasoline tank vent pipe: 1) Terminate in a U-bend as high above the weather deck as practicable, to prevent water entry and minimize vapor release. 2) Have a cross-sectional area not less than that of 19 millimeters OD tubing, to ensure adequate venting capacity. 3) Be connected to the tank at its highest point, to allow complete venting of the tank. All three of these requirements work together to provide safe and effective venting of the gasoline tank, which is critical for reducing fire and explosion hazards on small passenger vessels.
