APPENDIX A: HANDLING LIQUID NITROGEN
The safe handling and use of liquid nitrogen in cryogenic refrigerators and dewar flasks are largely a
matter of knowing the potential hazards and using common-sense procedures based on that knowledge.
There are two important properties of liquid nitrogen that present potential hazards:
At atmospheric pressure, liquid nitrogen boils at -196 °C. Very small amounts of liquid vaporize into large
amounts of gas. One liter of liquid nitrogen becomes 24.6 ft3 (700 L) of gas.
The safety precautions must be followed to avoid potential injury or damage which could result from these
two characteristics. Do not attempt to handle liquid nitrogen until you have read and fully understand the
potential hazards, their consequences, and the related safety precautions. Keep this manual handy for
ready reference and review.
Use only containers designed for low temperature liquids.
Cryogenic containers are specifically designed and made of materials that can withstand the rapid
changes and extreme temperature differences encountered in working with liquid nitrogen. Even these
special containers should be filled SLOWLY to minimize the internal stresses that occur when any
material is cooled. Excessive internal stresses can damage the container.
Do not cover or plug the entrance opening of any liquid nitrogen refrigerator or dewar. Do not use any
stopper or other device that would interfere with venting of gas.
These cryogenic liquid containers are generally designed to operate with little or no internal pressure.
Inadequate venting can result in excessive gas pressure which could damage or burst the container. Use
only the loose-fitting necktube core supplied or one of the approved accessories for closing the necktube.
Check the device periodically to be sure that venting is not restricted by accumulated ice or frost.
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 containers for pouring. For 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 devices and their accessories.

EDOC00092 –ULT RFID Freezer User Manual, REV6 –8/16/2023 16
Do not overfill containers.
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.
Nitrogen gas can cause suffocation without warning.
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, and tasteless. It cannot be detected by the human senses
and will be breathed as if it were air. Breathing an atmosphere that contains less than 18% oxygen can
cause dizziness and quickly result in unconsciousness and death.
Note: The cloudy vapor that appears when liquid nitrogen is exposed to the air is condensed moisture;
not the gas itself. The issuing gas is invisible.
Never dispose of liquid nitrogen in confined areas or places where others may enter.
Disposal of liquid nitrogen should be done outdoors in a safe place. Pour the liquid slowly on gravel or
bare earth where it can evaporate without causing damage. Do not pour the liquid on pavement.

EDOC00092 –ULT RFID Freezer User Manual, REV6 –8/16/2023 17
APPENDIX B: HANDLING LIQUID CO2
High concentrations of CO2gas can cause asphyxiation!
OSHA Standards specify that employee exposure to carbon dioxide in any eight-hour shift of a 40-hour
work week shall not exceed the eight-hour time weighted average of 5000 PPM (0.5% CO2). The short-
term exposure limit for 15 minutes or less is 30,000 PPM (3% CO2). Carbon dioxide monitors are
recommended for confined areas where concentrations of carbon dioxide gas can accumulate.
Store and use liquid CO2only 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 CO2gas reduce the concentration of oxygen and can result in asphyxiation.
Because CO2gas is colorless, odorless, and tasteless, it cannot be detected by the human senses and
will be breathed as if it were air. Breathing an atmosphere that contains less than 18% oxygen can cause
dizziness and quickly result in unconsciousness and death.
Note: The cloudy vapor that appears when liquid CO2is exposed to the air is condensed moisture; not the
gas itself. The issuing gas is invisible.
Never dispose of liquid CO2in confined areas or places where others may enter.
Disposal of liquid CO2should be done outdoors in a safe place. Pour the liquid slowly on gravel or bare
earth where it can evaporate without causing damage. Do not pour the liquid on pavement.
