Click here for a PDF version of this content.Introduction Compressed gas cylinders can be extremely hazardous when misused or abused. Compressed gas cylinders can present a variety of hazards due to their pressure and/or content.Depending on the particular gas, there is a potential for simultaneous exposure to both mechanical and chemical hazards. Gas Pressure Regulators High Pressure, Cylinder, Carbon Lab Low Pressure Liquid CylindersExcelling under pressure . Most specialty gases are supplied in cylinders compressed to high pressures. Pressure regulators reduce the pressure within the cylinders to a level that can be safely used in your operating system. Proper regulator selection is critical for both the safety and effectiveness of your operating systems. GASES UNDER PRESSURE HAZARDS & RISK 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. The cylinder can accelerate to speeds great enough to penetrate concrete walls. The pressure in a Lab Low Pressure Liquid Cylinders
Low -pressure dewars are used for supplying cryogenic liquid only. Pressure -relief valve setting 22 psi. In a low -pressure liquid nitrogen dewar, the pressure inside the vessel is maintained through the normal heat-leak of the cylinder .

Make sure you are aware of the presence of a protective pressure relief valve on any cylinder that you handle. 2. If there is a crack in the metal between the liquid and the vacuum space of a cylinder , a rapid pressure build-up in this relatively confined space will occur since it would no longer be insulated by vacuum.
Cryogenic liquid cylinders , sometimes also referred to as Dewars, are insulated, vacuum jacketed, pressurized vessels. They come equippmed with safety relief valves and rupture disks to alleviate pressure buildups. These cylinders come in Cryogenic Liquids - Hazards OSH AnswersLiquid Cylinders .
