Dry Ice Storage
The key to dry ice storage is to insulate the dry ice so that it stays cool, while at the same time making sure that it can breathe-- that the gas released from the dry ice can safely leave the storage area.
There are lots of ways to do this, but here are some pointers:
- Store the dry ice in a cooler, but leave the top of the cooler slightly loose.
- If you want to store the dry ice for more than 48 hours, buy at least two pounds.
- Provide many layers of breathable insulation. Wool blankets, styrofoam, newspaper, and fleece are all good insulators.
I store dry ice in a small cooler, wrapped in a blanket, and then placed inside a larger cooler.
