Compressed Gas and Cryogenic Liquid

Laboratory gases are supplied in high-pressure cylinders. These cylinders present their own hazards and must be stored, handled and used with extra care.  Cryogenic liquids are defined as liquids with a normal boiling point at or below -900C.  These can also present their own unique hazards.

The following two standards provide guidance on how to handle these materials:  

Compressed Gas Standard

Cryogenic Liquid Handling Standard


Cryogenic and Compressed Gas Safety (SO1030)
