How to take care of your liquid nitrogen while taking care of your own health.

Your safety is extremely important to us.

  • Liquid Nitrogen is extremely cold. At atmospheric pressure, liquid nitrogen boils at -320°F / -196° C.
  • Very small amounts of liquid vaporize into large amounts of gas. One liter of liquid nitrogen becomes 24.6 ft3/0.7 m3 of gas.
  • Never allow any unprotected part of your body to touch objects cooled by liquid nitrogen. Such objects may stick fast to the skin and tear the flesh when you attempt to free yourself. Use tongs, preferably with insulated handles, to withdraw objects immersed in the liquid, and handle the object carefully.
  • Keep container upright.
  • Keep the unit clean and dry at all times. Do not use strong alkaline or acid cleaners that may corrode the metal shell.
  • Use proper transfer equipment. Never use hollow rods or tubes as dipsticks.
  • Nitrogen gas can cause suffocation without warning. Store and use liquid nitrogen only in a well ventilated place.
  • Use only containers designed for low-temperature liquids.
  • Do not overfill containers
  • Wear protective clothing:
    ∙ Safety Goggles
    ∙ Cryo Gloves
    ∙ Trousers
    ∙ High-top Shoes

FIRST AID: In case of dizziness or suffocation from inhalation: remove victim to fresh air. If victim is not breathing, give artificial respiration. If breathing is difficult, give oxygen. Provide medical assistance. In case of frostbite, wash with lukewarm water for at least 5 minutes without rubbing. Obtain immediate medical treatment.
