Liquid nitrogen is often used as a refrigerant. Refrigerant can cause frostbite. A small amount of refrigerant can cause blindness when it comes into contact with the eyes. The rapid evaporation of gas generated by liquid nitrogen may cause oxygen deficiency in the site. Note the following when using and handling liquid nitrogen:
1. Wear insulated protective gloves.
2. Wear a long-sleeved lab coat with a knee length.
3. Wear shoes with ankles and no feet, wear protective glasses, and wear a protective mask if necessary.
4. Keep the ambient air flowing.
