Liquid Nitrogen
Liquid nitrogen subject to nuclear radiation (high neutron and gamma fluxes) must be kept free of oxygen to prevent explosions occurring in reactor cryostats. The explosive species generated is not nitrogen oxide or nitrogen dioxide because solutions of these will not cause explosion on contact with a drop of acrylonitrile, whereas irradiated oxygen …
Is Nitrogen/Liquid Nitrogen Flammable?
Liquid nitrogen is very hazardous and, in fact, even though it's used in the bar industry to make exciting cocktails with vapor coming off of it – this practice has caused serious injury in drinkers. This is because liquid nitrogen is so cold that it rapidly freezes any tissue that it comes into contact with along with any bodily fluids.

Liquid Nitrogen Temperature
At normal atmospheric pressure, nitrogen is a liquid between 63 K and 77.2 K (-346°F and -320.44°F). Over this temperature range, liquid nitrogen looks much like boiling water. Below 63 K, it freezes into solid nitrogen. Because liquid nitrogen in a usual setting is boiling, its usual temperature is 77 K. Liquid nitrogen boils into nitrogen ...

Liquid Nitrogen Safety | YSU
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 extreme.
