The acids we are exposed to in daily life are most commonly found in sulfuric acid, hydrochloric acid, and nitric acid. Acetic acid (glacial acetic acid), hydrofluoric acid, perchloric acid, and chromic acid are all corrosive. In addition to skin burns, the respiratory tract inhalation of volatile gases and mists of these acids (such as sulfuric acid mist, hydrochloric acid mist) can also cause severe irritation of the upper respiratory tract. In severe cases, chemical bronchitis, pneumonia and pulmonary edema can occur.
First-aid methods: 1. Immediately remove or cut off contaminated overalls, underwear, shoes and socks, etc., quickly rinse the wound with a large amount of running water for at least 10 to 20 minutes, especially for sulfuric acid burns, use a lot of water to quickly rinse, except to wash away In addition to dilute sulfuric acid, it can also flush away the heat generated by sulfuric acid and water.
2. After rinsing, wet it with 5% sodium bicarbonate for 10-20 minutes, then rinse with water for 10-20 minutes.
3. Debride, remove other pollutants, cover the sterile gauze and send it to the hospital.
4. Oral administration should not be gastric lavage, especially if it has been taken orally for some time to prevent gastric perforation. You can use water first, then oral milk, protein or peanut oil (it is not appropriate to take sodium bicarbonate to avoid carbon dioxide and increase the risk of gastric perforation). A large number of oral strong acid and on-site first aid are not timely, they are sent to the hospital for emergency treatment.
5. Inhalation of the respiratory tract and coughing, inhalation of 5% sodium bicarbonate solution or saline to wash the eyelids, the wounded can also immerse the face in the water to clean themselves.
