A chemical burn occurs when skin or eyes come into contact with a harmful substance, such as acids, alkalis, or solvents. These substances can cause damage to the skin, leading to redness, blisters, or even deeper tissue injury. The severity of a chemical burn depends on the type of chemical, concentration, and duration of exposure. Immediate treatment is crucial for minimizing damage. Rinsing the affected area with water can help remove the chemical and reduce irritation. In severe cases, medical attention may be necessary to manage pain and prevent complications. Always handle chemicals with care to avoid such injuries.
