Dry ice - is classified by DOT and IATA as a miscellaneous hazard, Class 9. It is also considered hazardous during transportation for the following reasons:
Explosion hazard: Dry ice releases a large volume of carbon dioxide gas as it sublimates. If packaged in a container that does not allow for release of the gas, it may explode, causing personal injury or property damage.
Suffocation hazard: A large volume of carbon dioxide gas emitted in a confined space may displace oxygen and create an oxygen deficient environment.
Contact hazard: Dry ice is a cryogenic material that causes severe frostbite upon contact with skin.
