For a dry chemical burn, what is the recommended initial action?

• A. Brush off and then rinse area with cool water, call 911
• B. Rub with water
• C. Apply oil
• D. Ignore

Answer: (A)

Dry chemical burns require removing the chemical first and then flushing it away with water. Gently brushing off any loose dry chemical stops it from continuing to react with moisture on the skin, which could worsen the burn. After the chemical is removed, rinse the area with cool running water to dilute and wash away any residue and to help cool the skin, reducing tissue damage. Rubbing should be avoided because it can spread the chemical and cause more injury, and applying oil is not helpful and can trap residues. If the burn covers a large area, involves the face or hands, or there are signs of a more serious injury, seek emergency medical help promptly.
