2. Scald: Do not wash the wound with cold water. When the skin of the wound is not broken, you can apply saturated sodium bicarbonate solution or use sodium bicarbonate powder to make a paste and apply it to the wound. You can also apply badger oil or scald cream; if the wound is broken, you can apply some purple potion Or 1% potassium permanganate solution.

If acid splashes into the eyes, rinse with plenty of water and take to hospital for treatment. But concentrated sulfuric acid cannot be washed with water when it sticks to the skin, because a lot of heat will be generated and it will burn the skin.
