How to store dry ice
Store dry ice in a well-insulated container. The thicker the insulation, the slower it will sublimate. Do not store dry ice in a refrigerator or a completely airtight container. Keep some ventilation around the dry ice storage containers, as the sublimated CO2 gas can sink too low and become dangerous.
INSULATED CONTAINERS
An inexpensive Styrofoam cooler from the grocery store will work for a short time. An ice chest used for camping or picnics will also work. A thick polystyrene box such as those used by Omaha Steaks or the insulated boxes from Control Temp Packaging will provide more extended storage. For commercial storage, several companies such as Polar offer a variety of larger containers shown here.DRY ICE SUBLIMINATION (changing from a solid to a gas) will vary depending on the insulation efficiency and the ambient temperature; on average, figure 10% to 25% loss per day.
CAUTION! Adequately ventilate your dry ice storage area because concentrations of CO2 can build up and be dangerous.
DO NOT leave dry ice unattended where children or others could take it. You may be liable for injuries.
