Introduction to Dry Ice
Dry ice is the solid form of carbon dioxide, priced by the pound. Commercial quantities cost around $0.50 per pound. Blocks and pellets are priced the same.
Dry Ice Usage and Safety

- It’s an alternative to regular ice for keeping items cold.
Safety Guidelines
- Do not store dry ice in a freezer as it turns to gas at -109.3° F.
- In small spaces, it can build up hazardous carbon dioxide gas.
- Contact with dry ice can cause frostbite. Always wear insulated gloves when handling.
