It is produced industrially by fractional distillation of liquid air..
Is liquid nitrogen dangerous to touch?
Liquid nitrogen is dangerous, and should always be handled carefully wearing a special glove meant solely for the purpose. If touched with bare hands, it will become numb for sometime, but will become functional witha slightly awkward feeling.

Liquid Nitrogen (LN2) Sprayer Freeze Treatment Instrument Unit 500ml (16oz.) from U.S. SOLID – Walmart.com – Walmart.com.
Can liquid nitrogen kill you instantly?
Nitrogen is typically a gas at room temperature, and transforms into its liquid state at minus 321 degrees Fahrenheit (minus 196 degrees Celsius). Directly submerging a limb or a finger in liquid nitrogen is dangerous because it can freeze tissue almost instantaneously.
Can liquid nitrogen kill bacteria?
Most recent answer. Freezing with liquid nitrogen at -196°C it is a good and reliable method for preservation of bacteria for long time. It is a fact like a sun shine.

Does liquid nitrogen cause hair loss?
Potential side effects include bleeding, blister formation, headache, hair loss, and hypopigmentation, but rarely scarring. Skin lesions often can be treated in a single session, although some require several treatments. Cryosurgery has been used to treat skin lesions for approximately 100 years.
Why is cryogenic freezing?
Cryogenic freezing is the process of preserving a dead body with liquid nitrogen. Advocates believe that scientists will one day work out how to warm the bodies up and bring them back to life, by which time doctors might be able to cure cancer and other diseases which are untreatable today.
