53. Liquid Nitrogen Use proper transfer equipment Use a phase separator or special filling funnel to prevent splashing and spilling when transferring liquid nitrogen into or from a dewar or refrigerator The top of the funnel should be partly covered to reduce splashing Use only small easily handled dewars for pouring liquid For the larger heavier containers use a cryogenic liquid withdrawal device to transfer liquid from one container to another Be sure to follow instructions supplied with the withdrawal device When liquid cylinders or other large storage containers are used for filling follow the instructions supplied with those units and their accessories Do not overfill containers Filling above the bottom of the necktube or specified maximum level can result in overflow and spillage of liquid when the necktube core or cover is placed in the opening Never use hollow rods or tubes as dipsticks When a warm tube is inserted into liquid nitrogen liquid will spout from the top of the tube due to gasification and rapid expansion of liquid inside the tube Warning Nitrogen Gas Can Cause Suffocation Without Warning A Store and use liquid nitrogen only in a well ventilated place As the liquid evaporates the resulting gas tends to displace the normal air from the area In closed areas excessive amounts of nitrogen gas reduce the concentration of oxygen and can result in asphyxiation Because nitrogen gas is colorless odorless
