Liquid Nitrogen - an overview | ScienceDirect Topics
Liquid nitrogen (LN) is an inert cryogenic fluid with a temperature of − 196 °C [− 320 °F]. LN is injected directly into the batch water storage tank, aggregate, or mixer via lances to lower the temperature of the concrete as much as practical without freezing. LN can be stored at the batch plant or on the project site and if used on the ...

Liquid Nitrogen - an overview | ScienceDirect Topics
Nitrogen boils at a lower temperature than oxygen, so oxygen will condense on materials that are cooled with liquid nitrogen. If these materials are flammable, a fire or explosion can occur. Some pork rind that had to be ground was cooled with liquid nitrogen. When the grinder was started up, it exploded, and two men were killed.

Liquid nitrogen - Hazards & Safety precautions - HSEWatch
Asphyxiation. Liquid nitrogen expands 695 times in volume when it vaporizes and has no warning properties such as odor or color. Hence, if sufficient liquid nitrogen is vaporized so as to reduce the oxygen percentage to below 19.5%, there is a risk of oxygen deficiency which may cause unconsciousness. Death may result if oxygen deficiency is ...
