When moving cylinders, only transport them using a cylinder cart specifically designed to handle and move CO2 tanks. 3) General Safety Precautions Of Compressed gas cylinder: Name of the gas and chemical formula shall be mark on the cylinder. Compressed gas cylinders can present a variety of hazards due to their pressure and/or contents. For basic safety information on the handling of compressed gas containers, refer to CGA P-1, Safe Handling of Compressed Gases in Containers.In addition, all of the precautions necessary for the handling of any nonflammable gas or cryogenic liquid must be taken; see your liquid nitrogen supplier’s safety data sheets and CGA P-9, The Inert Gases, Argon, Nitrogen, and Helium. When not in use, all compressed gas cylinders must have a valve cap on. It is illegal to ship compressed gas in cylinders that have been exposed to fire. If you must move a cylinder over a lip or uneven surface, rotate the cylinder in circular fashion over the lip one … The health effects described in this Fact Sheet may occur at concentrations greater than 80%.
