About Liquid Nitrogen:
It is an inert, colorless, odorless, noncorrosive, nonflammable and extremely cold element.
It is a cryogenic liquid (Cryogenic liquids are liquefied gases that have a normal boiling point below –130°F (–90°C). Liquid nitrogen has a boiling point of –320°F (–196°C).
Health impacts:
Liquid nitrogen can scorch the organ or part of the body it contacts, making it appear like frost bites.
It can damage the lips, tongue, throat, lungs and stomach. It may cause lesions or burn tissues.
If it reaches the stomach, the organ could get perforated. In the lungs, it could produce CO2 and the person could become unconscious.
Applications:
It is used to cool and freeze food rapidly. In food production and industrial processes, a cooling tray filled with liquid nitrogen is used to rapidly cool materials or equipment by immersing the product in nitrogen.
In the wellness and sports industry, cryosaunas with liquid nitrogen vapor are used for
Liquid nitrogen test chambers are used in technology and material sciences to test the performance and durability of materials and devices at extremely low temperatures.
