Dry Ice Safety Precautions

  • Avoid storing dry ice in an air-tight container without the proper ventilation; the carbon dioxide gas is constantly sublimating from the ice, and expands, potentially causing any airtight container to explode. Dry ice is best transported in a Styrofoam container or insulated cooler with the lid gapped. 
  • If dry ice is transported in a vehicle, be sure to have proper ventilation. CO2 gas can be toxic.
  • Avoid entering closed storage areas that contain dry ice, such as walk-in coolers or box trucks. Sublimated CO2 gas sinks to the low areas and replace oxygenated air and can be an asphyxiation hazard. Air the space out completely prior to entry. 
  • Be aware of symptoms of breathing CO2 gas, including panting or rapid breathing.
  • Avoid storing dry ice in your refrigerator freezer if it is running. The extremely cold temperature will cause your thermostat to turn off and therefore shutdown your freezer. Note: If your refrigerator/freezer breaks down or the power goes out, dry ice can be beneficial by helping to keep things frozen in an emergency. It is safe to place dry ice in your refrigerator only when the unit is completely turned off/power is out. Contact Greco Gas with any questions.
  • Do not allow dry ice to come in contact with bare skin; there is risk of severe burns. Gloves must be worn at all times when handling this product. If gloves are not handy, an oven mitt or folded towels will sufficiently protect the skin for short periods of handling. 
  • Skin exposed to or “burned” from touching dry ice should be run under tepid – not hot – water. If skin becomes blistered or peels off, seek medical attention.
  • Keep dry ice out of the reach of children.
  • Don’t place dry ice directly on plastic or glass shelving or Formica countertops, as these surfaces may crack or break.
