On a vapor control system, what must each vessel's vapor connection flange have?

A stud at least 1" long projecting from the flange face
B 6" reducer
C pressure gauge permanently attached to the flange
D hose saddle
AI Explanation

The correct answer is A) Each vessel's vapor connection flange must have a stud at least 1" long projecting from the flange face. This requirement is specified in the US Coast Guard regulations for vapor control systems on vessels. The stud on the flange helps ensure a secure, tight connection when the vapor recovery hose is attached, preventing any potential leaks of volatile vapors. The other answer choices are incorrect because: B) a 6" reducer is not required, C) a pressure gauge is not mandated on the flange, and D) a hose saddle is not a regulatory requirement for the vapor connection flange.
