Dry ice should be stored in an insulated container. This will reduce the rate of sublimation, making your dry ice last longer.

WARNING: Dry Ice should never be stored in an airtight container. As the dry ice reverts to a gas, it will cause a potentially dangerous build-up of pressure in an airtight container.

Ensure that the container is not completely airtight as the sublimation of dry ice to CO2 gas will cause an airtight container to expand or possibly explode. As a result of this, a certain amount of CO2 will inevitably enter whatever room you are using to store the dry ice. Hence the importance of keeping your storage room well-ventilated.

Polar Ice can advise on suitable packaging and storage solutions for your dry ice. We have a variety of different options to cater for different quantities of dry ice, from 10kg to 1000kg plus.

Ventilation

In small amounts, CO2 is harmless, but in larger quantities it can lead to shortness of breath or even asphyxiation. It is important to always use dry ice in a well-ventilated area. If dry ice has been stored in a room or vehicle for more than 10 minutes then you must open a door or window and allow adequate ventilation.

Note: If you working with or near dry ice and suddenly find you are having difficulty breathing or are out of breath, open any nearby windows and vacate the area for at least 10 to 15 minutes.
