For skin contact resulting in frostbite or cryogenic burns, the affected area should be warmed gradually using lukewarm water, and medical attention should be sought immediately. Do not use hot water, direct heat, or rub frostbitten skin, as this can cause further damage to the tissue.
If clothing becomes soaked, it should be removed immediately. If clothing becomes frozen to the skin, pour cool water on it and do not attempt to remove it until it is completely free from the skin.
If liquid nitrogen has caused eye exposure, the eyes should be rinsed thoroughly with lukewarm water for at least 15 minutes, and medical help should be obtained promptly.
