减压装置为容器提供过压保护。
Pressure relief devices provide protection against excessive pressure in the container.
液氦有凝固空气的潜力，这会阻塞减压装置和其它的容器开口，导致可以使容器破裂的压力积累。
Liquid helium has the potential to solidify air, which can block pressure-relief devices and other container openings. This can result in pressure buildup that may rupture the container.
警告：禁止直接让水流向正排出的氧。水会结冰并堵塞减压装置的出口，这会造成容器故障。
Caution: Do not direct water streams toward venting oxygen. The water will freeze and plug the pressure-relief vent, which may result in container failure.
