The storage methods of dry ice mainly include freezer storage, thermos storage and incubator storage. These preservation methods are to keep dry ice at low temperature and prevent sublimation.

When using dry ice, we must first ensure the clean and dry environment and use the incubator to slow down its sublimation speed. Because the temperature of dry ice is extremely low, do not touch it directly with your hands to avoid frostbite. After use, dry ice will be kept at low temperature for a period of time, so it should be properly handled to avoid being discarded at will.

Safety is very important in the process of using dry ice. Once the leakage of carbon dioxide gas is found, it should be stopped immediately and ventilated quickly to ensure the safety of personnel. As a refrigerant, dry ice is widely used in artificial rainfall, smoke generation and other fields, but it must be used in accordance with safety regulations.
