1) Before transportation, the lifting drums should be accurately fixed in the groove of the container mouth, and the neck plug should be covered.

2) The liquid nitrogen tank can only be placed upright, not lying down. In order to prevent overturning and alleviating impact, sponge or other cushion should be used. The cushion must be padded in wooden frame and fixed with belt or other articles. The tank should be separated from the tank by fillers to prevent bumping and collision and tipping. When loading and unloading trucks, it is necessary to guard against the collision of liquid nitrogen tanks, not to drag them on the ground at will, so as to avoid reducing the service life of liquid nitrogen tanks.

3) When transported and transported by vehicles, liquid nitrogen oscillates with the vibration of the vehicles, thus increasing the loss rate. The rate of increasing the amount of mourning varies with the shape of the container. For example, if a 10 liter liquid nitrogen tank is transported for eight hours a day, the amount of mourning will not be 100 grams (containing 0.12 liters) while the amount of mourning will also increase due to the manipulation of removing the handle. For example, the amount of mourning will be about 10 grams per 10 liter operation, in order to reduce the activity and tranquility of the storage. Transportation, liquid nitrogen tanks to be coated or wooden boxes wrapped, especially on the way to prevent the liquid nitrogen tank upside down, in order to avoid chaos.

4) When transported by aircraft, in addition to strictly preventing the container from turning over, it should also be packed in wooden boxes in order to prevent the abnormal situation caused by the rapid boiling of liquid nitrogen as the air pressure drops.

5) When transporting liquid nitrogen, please use transport tanks (model with "B") and prohibit the use of storage tanks as transport tanks. Liquid nitrogen tanks should be transported and opened as few times as possible.
