We've all heard the uses of liquid nitrogen and its unique properties that help scientists around the world discover new and amazing things. However, without the proper liquid nitrogen equipment and other precautions, the substance can quickly become very dangerous to those around the substance.
Recently, an astrophysicist in Egypt was cooling a charged coupled device camera for the observatory's telescope. He was carrying a cryogenic storage vacuum flask of liquid nitrogen which was to contain the heat coming off of the camera. The flask exploded, giving the astrophysicist severe chest and hand cold burns from the bursting liquid nitrogen.
Liquid nitrogen transfers to nitrogen gas of a rapid ration of 1:694, which is why the substance exploded. If you pour two gallons of liquid nitrogen into any warm vacuum it suddenly and immediately evaporates into a gas in front of your eyes. The properties of the substance are very dangerous for those who are unfamiliar with the safety precautions or liquid nitrogen equipment.
The gas is used for observatory and lab work but is more commonly used in refrigeration. Foods and goods can be transported around the world with the use of cryogenic storage. Liquid nitrogen is also vital in the cryopreservation of blood, reproductive cells and other biological samples.
It's also used in low temperature medical treatment in some dermatology cases. Also, construction companies may be able to use liquid nitrogen to freeze damaged water pipes and stopping water leaks during the fixing process. In the military, liquid nitrogen is used in heat-seeking missiles to prevent sensors from getting confused by their own heat signals or by the heat form the planes that are launching them.
There are so many applications of liquid nitrogen, but you need the proper liquid nitrogen equipment to ensure that the safety of everyone is preserved.
