The health effects of diminished oxygen in the environment can be acute and the impact severe as detailed below. This results in an oxygen-deficient atmosphere, particularly if vented into a closed space, and asphyxia can result. When LN2 boils it produces gaseous nitrogen, which displaces oxygen from the air. Hazards associated with Liquid Nitrogen Asphyxiation Its properties are listed in the following table.ΔΆ. LN 2 (liquid nitrogen) is a cryogenic liquid and is the liquefied form of nitrogen gas at atmospheric pressure and subzero temperature. Liquid nitrogen is commonly used across Monash University for the purposes of snap-freezing and long-term storage of biological samples and in cold traps on vacuum lines/equipment 1.
