Liquid nitrogen is a common low-temperature working fluid, which is widely used in scientific research, medical treatment, chemical industry and other fields. Proper use of liquid nitrogen is critical to work efficiency and personal safety. Below we introduce the correct use of liquid nitrogen and safety precautions.

the correct use of liquid nitrogen:
1. Storage of liquid nitrogen: Liquid nitrogen should be stored in a well-ventilated place, away from heat sources and flammable materials. Do not place liquid nitrogen in a closed container to prevent accidents caused by excessive pressure.
2. Wearing protective equipment: In the process of handling liquid nitrogen, it is necessary to wear protective equipment such as protective gloves, goggles and protective clothing to prevent liquid nitrogen from splashing and direct contact with skin.
3. Avoid direct contact: The temperature of liquid nitrogen is extremely low. Avoid direct contact with skin or other objects during use to avoid burns.

of liquid nitrogen safety precautions:
1. to avoid the volatilization of liquid nitrogen: liquid nitrogen at room temperature easy to volatilize into a gaseous state, to avoid use in confined spaces, to avoid inhalation of excessive nitrogen on the body harm.
2. Avoid excessive spraying of liquid nitrogen: When using liquid nitrogen, avoid excessive tilt and excessive spraying to avoid large-area scattering of liquid nitrogen and causing accidents.
3. Regularly check the status of the equipment: Regularly check the status of the liquid nitrogen container and the equipment used to ensure tightness and safety. The correct use of liquid nitrogen in

is the key to ensure work efficiency and personal safety. Follow the above usage methods and safety precautions to better protect the safety of yourself and others. I hope the above content can help you, thank you for reading.
