Liquid nitrogen, with its extremely low temperature of -196°C (-321°F), is a powerful tool used in various fields, from medicine to culinary arts. However, it can cause severe burns if mishandled. These burns, known as cryogenic burns, occur because liquid nitrogen can instantly freeze skin tissue upon contact. This rapid freezing causes ice crystals to form in cells, leading to cellular damage similar to thermal burns.

Handling liquid nitrogen with respect and proper safety measures can prevent accidents and ensure its benefits are enjoyed safely.

• Liquid nitrogen has an extremely low temperature of -196°C (-321°F).

• It is widely used in fields such as medicine and culinary arts.

• Direct contact with liquid nitrogen can cause cryogenic burns.

• Cryogenic burns occur because liquid nitrogen instantly freezes skin tissue.

• The rapid freezing forms ice crystals in cells, leading to cellular damage.

• Symptoms of liquid nitrogen burns include intense pain, redness, blistering, and numbness.

• Always use personal protective equipment, like insulated gloves and face shields, when handling liquid nitrogen.

• In case of contact, quickly remove any affected clothing or jewelry.

• Immerse the affected area in lukewarm water (not hot) to thaw the frozen tissue.

• Seek immediate medical attention to ensure proper treatment and prevent complications.
