Gas Cylinders

Information

Compressed gas cylinders are used in all of the Biochemistry labs with as many as 350 cylinders in the building at any time. Cylinders are received on the loading dock and delivered by shipping/ receiving personnel.  Empty tanks are picked up when the new tanks are delivered, please mark empty tanks with the magnetic "EMPTY" tags as you finish with them. 

These gases vary from extremely flammable (acetylene) to extremely inert (helium). Many compressed gas cylinders are stored at extremely high pressures (up to 2,500 pounds per square inch gauge or PSIG). A sudden release of these gases can cause a cylinder to become a missile-like projectile. Cylinders have been known to penetrate concrete-block walls. If handled properly compressed gas cylinders are safe. If handled improperly, the same cylinders can present a severe hazard to you and the surrounding area.

Types of Hazards

• Physical Damage: Cylinders are very hazardous when exposed to damage from falling over, tipping, heat, electric circuits, motion, vibration, or anything that can cause a weakness or crack in the cylinder wall or shell. Such damage can cause the cylinder to rupture and explode sending sharp metal pieces, like shrapnel, blasting through the area.
• Tipping and Falling: The most common hazard associated with cylinders occurs when cylinders tip or fall over. Since cylinders are heavy and awkward to handle, they require special care and equipment in handling and securing so they do not fall or tip over and cause injury.
• Valve Leakage: Cylinder valves can leak, causing their contents to discharge. To minimize hazards from leaks, use proper ventilation and storage. 

Users of Compressed Gas Cylinders must read, understand, and follow the markings on the cylinder, the label(s) on the cylinder, and the material safety data sheets (MSDS). Appropriate personal protective equipment should be worn.
