Dry ice belongs to the ninth category of miscellaneous dangerous goods: during transportation, due to its extremely low melting point, special dry ice storage boxes must be used, and dangerous goods with temperature control devices must be arranged.

Relevant instructions

Remember that every time you come into contact with dry ice, you must be careful and use thick cotton gloves or other coverings to touch dry ice! If it is in direct contact with the skin for a long time, it may cause cell freezing and damage similar to mild or extremely severe frostbite. Dry ice cannot be used in relatively sealed places such as cars and ship cabins, because the sublimated carbon dioxide will be denser than oxygen, so it will crowd out oxygen and may cause shortness of breath or even suffocation!

Place dry ice in an insulating box: An insulating box with good thermal insulation effect can slow down the sublimation rate of dry ice.

Because the pressure generated by the sublimation of dry ice can cause an explosion, dry ice cannot be stored in an airtight insulated box.
