1. Quickly flush the area with large amounts of water, using a shower or hose, if available. Do not apply water too forcefully. Continue to flood the area while the clothing, including shoes and socks, is being removed, as well as afterwards.
NOTE: There are two exceptions to the above. In alkali burns caused by dry lime, the mixing of water and lime creates a very corrosive substance. Dry lime should be brushed away from the skin and clothing, unless large amounts of water are available for rapid and complete flushing. In acid burns caused by phenol (carbolic acid), wash the affected area with alcohol because phenol is not water soluble; then wash with water. If alcohol is not available, flushing with water is better than no treatment at all.
2. After thorough washing, neutralize any chemical remaining on the affected area. WARNING: DO NOT attempt to neutralize a chemical unless you know exactly what it is and what substance will neutralize it. Further damage may be done by a neutralizing agent that is too strong or incorrect. For acid burns make a solution of 1 teaspoon of baking soda in a pint of water and flush it over the affected area. For alkali burns mix 1 or 2 teaspoons of vinegar in a pint of water and flush it over the affected area.
3. Flush the area again with water and gently pat dry with a sterile gauze. Do not rub the area.
4. Transport the victim to a medical treatment facility.
