Where must LPG locker vents be led outboard?

Leading LPG locker vents outboard ensures that any potential leakage of liquefied petroleum gas can safely escape to the open air, reducing the risk of gas accumulation inside the locker or the vessel. The requirement for these vents to be lower than the locker bottom but still above the waterline is crucial.

When vents are positioned lower than the locker bottom, they allow any heavier-than-air gases, which LPG can be, to escape downward. If the vent exits above the waterline, it ensures that water cannot enter the locker through the vent during typical conditions, maintaining the integrity of the locker and preventing potential water-related damage or hazards.

Combined, these requirements help to maximize safety on board by ensuring that any gas released has a clear path to disperse into the atmosphere, decreasing the risk of explosion or asphyxiation and enhancing overall vessel safety during operation and in docked situations.
