How to do after dry ice frostbite
Dry ice is not ice, it is not formed by the solidification of water, but a colorless gas in the form of solids - carbon dioxide. Its temperature is -78.5 degrees Celsius, and when it is sharply sublimated, the temperature of the surrounding air is rapidly reduced. If the human body is in direct contact with dry ice, the skin tissue will be over-stimulated by the cold, resulting in trauma. After frostbite, the skin will have erythema, blisters, and pain, and the symptoms are similar to burns.
If the skin of the frostbite is only erythema or small blisters, just apply some frostbite plaster to the affected area and it will recover after a while. Do not puncture the blisters or tamper with the wound to prevent the wound from being exposed and infected. If the frostbite area is too large, or if you have a large blisters (more than 1cm in diameter), or if you are infected, please seek medical advice.
If the wound adheres to the clothing cloth during the frostbite of dry ice, it is caused by local freezing at low temperatures. At this time, do not rush to tear off the fabric and apply warm water at 37~38 degrees Celsius for rinsing. When the ice melts, the fabric will fall off on its own, avoiding blistering and infecting the wound.
If you take dry ice with your hands, dry ice will immediately stick to people's skin, causing very painful frostbite. Therefore, shovel is used in general contact with dry ice. In the absence of a shovel, if it is a short-term contact, cotton gloves can be used for prevention work, but the contact time is too long, such as 10 to 20 minutes, the cotton gloves will also lose their effect, causing the consequences of frostbite. Therefore, even if you are wearing a container or packaging, use professional dry ice gloves for protection.
