Because the liquid refrigerant evaporates rapidly in the environment, when the refrigerant falls on the skin, it will absorb a large amount of heat from the skin and vaporize, causing local frostbite. So prevent refrigerant from splashing into eyes and skin.2. Do not contact with open flames, stay away from heat sources, and avoid strong vibrations.
