OSHA Laboratory Safety: Cryogens and Dry Ice Fact Sheet


Laboratory Safety: Cryogens and Dry Ice

Cryogens are substances used to produce very low temperatures [below -153°C (-243°F)], such as liquid nitrogen (LN2) which has a boiling point of -196°C (-321°F), that are commonly used in laboratories. Although not a cryogen, solid carbon dioxide or dry ice which converts directly to carbon dioxide gas at -78°C (-109°F) is also often used in laboratories. Cryogens, as well as dry ice, can be hazardous to workers if not handled properly.
