Symptoms of Chemical Burns
Chemical burns of the skin usually cause symptoms similar to superficial (first-degree) burns. The area is red, swollen, and painful but does not develop blisters. Sometimes, burns are deeper, with blisters and severe pain. Rarely, a strong acid or alkali will cause a full-thickness (third-degree) burn, that damages the skin all the way through.

Treatment of Chemical Burns
The steps in stopping chemical burns are
Remove contaminated clothing.
Brush away any dry powders or particles.
Rinse the area with large amounts of water.
Because chemicals can continue to inflict damage long after first contacting the skin, rinsing should continue for at least 30 minutes. In rare cases involving certain industrial chemicals (for example, metal sodium), water should not be used because it can actually worsen the burn. In addition, some chemicals have specific treatments that can further reduce skin damage. Further treatment of chemical burns is the same as treatment for thermal burns Treatment Burns are injuries to tissue that result from heat, electricity, radiation, or chemicals.
