Safety requirements for handling cryogenic freezing media.

ALT_TAG_GOES_HERE

IN CASE OF FROSTBITE OR OTHER INJURY, OBTAIN MEDICAL TREATMENT IMMEDIATELY.

 

  • Only properly-trained users should handle cryogenic freezing media such as liquid nitrogen and dry ice.
  • NEVER allow cryogenic freezing media to come into contact with skin or eyes. This will cause immediate burn or frostbite; and prolonged contact can lead to permanent eye damage and/or life-threatening injuries.
  • Proper safety gear should be equipped when handling cryogenic freezing media. This includes gloves specifically designed for this purpose, safety glasses, and protective clothing such as closed-toe shoes and long pants. Safety gloves should also be worn when handling the Seal’N Freeze plastic insert tray to separate individual samples following freezing.
  • Use forceps to avoid direct exposure to freezing media when placing an insert tray into the Seal’N Freeze box, and when removing a tray from the box.
  • To prevent tipping, use the Seal’N Freeze box only on a level surface, and avoid quickly swinging the box’s lid open and shut.
  • Excess freezing media should be disposed of in accordance with your lab’s standard safe-handling procedures. Allow the surplus of freezing media to evaporate or sublimate inside a fume hood or other well-ventilated area. Never dispose of liquid nitrogen or dry ice in the sink, toilet, or garbage.
