A cryogenic liquid is a liquid cooled below its normal boiling point below –90°C. Argon, helium, hydrogen, nitrogen and oxygen are the most common industrial gases transported, handled and stored in a liquid state at cryogenic temperatures.
Liquid CO2 is not below 90oC, but in my opinion it should be mentioned, because of the risks when leaking.
Due to these extremely low temperatures and the high rate at which these gases can convert from liquid to gas, a number of precautions and safe practices must be observed. Specific precautions must also be followed to prevent liquid reacting with contaminants or other hazards associated with particular products such as asphyxiation or flammability.
Visit our safety documents section to find out which safety guidelines must be applied by you. As always, end users should be thoroughly familiar with the product-specific Material Safety Datasheet (MSDS). All operators must have a thorough knowledge of the equipment required in conjunction with cryogenic gases.
