1. The container can only be used for filling liquid nitrogen, and can not be filled with liquid air and liquid oxygen to prevent them from burning violently with certain substances in the container.

2. Liquid nitrogen is a cryogenic liquid (196 °C).Splashing into the skin will cause like burns frostbite.So when you pump and remove the liquid nitrogen,you should be with epithelial gloves, not barefoot or wearing slippers.

3. Use of storage tanks for transportation tanks is banned.If you need to transport liquid nitrogen, you must use a transport type liquid nitrogen tank.For example,YDS - 30B is a special liquid nitrogen transport tank.This tank has a special shockproof structure, which is durable and not easy to damage.

4.Our factory matching neck plugs cannot be replaced with other plugs and cannot use the sealing plug,in order to avoid the evaporation of liquid nitrogen increasing pressure and causing boom to damage the container.

5. When checking the liquid level of the container, insert the solid plastic small rod or small stick to insert the bottom. After 5-10 seconds, the length of the frosting is the level of the liquid level.

Never use an empty stick or plastic tube,otherwise liquid nitrogen will come out of the tube to damage man.

6.Although nitrogen is non-toxic, tasteless, odourless gas,in the case of poor ventilation, evaporation of nitrogen can cause indoor nitrogen content increased and the oxygen content is less.This will lead the body to the danger of suffocation.Therefore,indoor ventilation should be strengthened in the storage and operation locations of liquid nitrogen containers to keep the air fresh.
