The Research Support Team of the EHS Division provides support with work planning for the safe handling of cryogenic liquids and review of cryogenic liquid equipment. This most commonly includes the use of liquid nitrogen, liquid argon, liquid helium, and dry ice. While dry ice is not technically a cryogenic liquid, it presents many of the same hazards, such as extremely cold temperatures and oxygen displacement. The cryogenic liquids subject matter expert reviews the use of all custom-built or modified cryogenic liquid equipment to ensure safety and performs oxygen deficiency hazard analysis for the storage of cryogenic liquids and dry ice in enclosed areas such as indoor laboratories and storage rooms.
The Health and Safety Manual chapter on Cryogenic Liquid Safety (Chapter 29) provides information on the Lab’s cryogenic liquid safety policies and procedures. You may also contact the cryogenic liquids subject matter expert at any time for help with oxygen deficiency hazard analysis, review of any work involving cryogenic liquids, or any general questions about cryogenic liquid use and safety.
