Laboratory liquid nitrogen tank does not belong to dangerous goods, but liquid nitrogen stored is cold, skin contact with liquid nitrogen can cause frostbite. As in the atmospheric pressure generated by excessive nitrogen, can make the partial pressure of oxygen in the air decreased, causing hypoxia suffocation.
Skin contact: If frostbite, seek medical attention.
Inhalation: Remove field induced fresh air and keep unobstructed breathing. If breathing is difficult, give oxygen. If breathing stops, artificial respiration immediately and seek medical advice.
Therefore, Tian Chi liquid nitrogen tank technical staff tips: laboratory staff due to the need for long-term exposure and use of liquid nitrogen tank, you should understand the characteristics of liquid nitrogen tank. To prevent accidents from happening.
