When operating liquid nitrogen container containing liquid nitrogen, we need to fully understand the safety issues so as not to cause harm to us. What are the safety issues?
(1) If we use the liquid nitrogen container to freeze the semen, use the tweezers to remove the semen. If the skin is directly in contact with the metal keg, it will be stuck and torn.
(2) When storing items in the container, slowly insert objects to prevent liquid nitrogen from spilling. Because the liquid nitrogen will boil when the object is inserted, it may spill out of the tank and the action should be slow when filling the nitrogen.
(3) Only use the neck plug of the liquid nitrogen container to prevent liquid nitrogen from volatilizing. If other plugs are used, the pressure in the liquid nitrogen tank may increase and explode or cause liquid nitrogen loss.
