What is the minimum diameter for the dedicated vent at the bottom of an LPG locker?

The correct minimum diameter for the dedicated vent at the bottom of an LPG locker is 1/2 inch ID. This specification is established to ensure proper ventilation and safe discharge of any potential leakage of liquefied petroleum gas (LPG). LPG is heavier than air, and thus, it tends to accumulate in low areas. A vent with a diameter of at least 1/2 inch ID provides sufficient flow area to allow adequate air exchange and helps prevent gas build-up, reducing the risk of explosion or fire. Adhering to this standard is critical for maintaining safety in marine environments where LPG is used, ensuring that any leaked gas can escape quickly and efficiently.
