Liquid Nitrogen Environmental Health and Safety USU

Liquid nitrogen storage consists of a liquid phase and a gaseous phase. If cyrovials are immersed in the liquid phase, liquid nitrogen can enter the closed cyrovials during storage. The cryovial may then explode when it is removed from storage due to the vaporization and expansion (1:696 expansion ratio) of the liquid nitrogen inside the cryovial.
