How should an accidental injury from liquid HCFC-22 be treated?

Liquid HCFC-22, or hydrochlorofluorocarbon-22, is known to cause cold burns or frostbite upon contact with skin due to its low boiling point. When liquid HCFC-22 evaporates, it can create extremely low temperatures capable of freezing tissue, leading to frostbite injuries.

Therefore, treating an accidental injury from liquid HCFC-22 as a frostbite injury is appropriate. In such cases, the affected area should be gently warmed to restore normal temperature and prevent further tissue damage. It is crucial not to apply direct heat, such as hot compresses or immersion in boiling water, as this could aggravate the injury. Proper medical care should also follow to assess the severity of the injury and prevent complications.

Recognizing the nature of the injury is vital for effective treatment, which is why identifying it as a frostbite injury is the correct approach.
