Tell us about the procedure for providing first aid for burns with chemicals. What is the difference in first aid for burns with acids and alkalis?

Chemical burns occur as a result of exposure to the skin and mucous membranes of concentrated organic and inorganic acids, alkalis, phosphorus. Certain chemical compounds in the air, in contact with moisture or other substances, can ignite or explode, resulting in thermochemical burns (phosphorus).
When providing first aid, first of all, it is necessary to remove clothes from the victim. If a chemical substance gets on your skin, wash it off with plenty of water until a specific odor disappears. Do not flush chemical compounds that ignite or explode when in contact with water, or treat affected skin with swabs and napkins moistened with water, as this results in rubbing the poisonous substance into the skin. Then, a clean dressing should be applied to damaged areas of the skin, which can be impregnated with a neutralizing or disinfecting agent. Ointment (vaseline, fatty, oily) dressings are contraindicated, as they accelerate the penetration of fat-soluble chemicals (e.g. phosphorus) under the skin. After dressing, give the victim a pain reliever.
If acid comes into contact with the skin, rinse the affected areas with plenty of water, then wash them with 2% solution of drinking soda or soapy water and apply a clean, dry dressing.
If the skin is affected by phosphorus and its compounds, it must be treated with a 5% solution of copper sulfate, and then with a 5-10% solution of drinking soda.
First aid for alkali burns is the same as for acid burns, but they must be neutralized with a 2% solution of boric acid or a solution of citric acid (table vinegar).
