Dry Ice Storage
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 good ventilation wherever dry ice is stored. The sublimated CO2 gas will sink to low areas and can be dangerous.
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 Omaha Steaks uses or the insulated boxes from Control Temp Packaging will provide for longer storage. For commercial storage, there are several companies offering 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 20% loss per day.
Caution. Be sure the area your dry ice is stored is well ventilated as 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.
