last night someone left a valve on, now we’re spilling liquid nitrogen!

Asphyxiation from oxygen displacement in liquid nitrogen is a very real risk and should be of great concern. Liquid nitrogen expands nearly 700 times into a gas as it warms. Because nitrogen gas is colorless and odorless, victims cannot sense the lack of oxygen and can pass out or die within seconds.
