Properties of dry ice

Dry ice is called the solid form of carbon dioxide. Unlike ordinary ice, it naturally turns into a gas, bypassing the liquid form.

The process of transition to a gaseous state is called sublimation. In this case, the ice turns into a thick vapor that does not have a pronounced odor.

Even a short stay in the open air leads to sublimation. It happens quite quickly. For example, when transporting a product in special containers, there is a volume loss of about 10% in 24 hours. In case of violation of the necessary conditions, this indicator increases.

That's why it's important to know: how to store dry iceright.

Rules and features of storage

Special isothermal containers are used to store the product. They are made with multilayer walls. The task of such boxes is to isolate dry ice from atmospheric air and delay the sublimation process as much as possible.

  • It is advisable to protect all exposed areas of the body with clothing.
  • Cover your face with a mask or goggles to protect your eyes.
  • Do not put the product in airtight, tightly closed containers. The accumulation of carbon dioxide gradually increases the pressure inside the container. This may cause an explosion. Otherwise, a person who opens the lid risks injuring their hands and face.

  • If some dry ice remains unused, it must be disposed of by evaporation.
