Sudden high pressure surge, as might be encountered by the start-up of a large fire pump may lead the valve clapper to lift momentarily, allowing water to flow through grooves in the valve seat to the retard chamber.

GASES UNDER PRESSURE HAZARDS & RISK MINIMIZATION
ehs.unl.eduthe common primary hazard of all GHS groups being high pressure contained in the cylinder. Gases in high-pressure cylinders contain an extraordinary amount of stored energy. If a cylinder valve is breached (i.e., breaks off when the cylinder falls and strikes a hard surface, etc.), the stored energy in the cylinder is released as thrust.

Use a back flow preventative device in the piping. Use only equipment of compatible materials of construction. Open valve slowly. Use only with equipment cleaned for Oxygen service.
