GASES UNDER PRESSURE HAZARDS & RISK MINIMIZATION

the 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.
