What should I do if my skin is irritated by welding sparks?

When the skin is injured by welding light, the following measures can be taken for treatment: 1. Immediately leave the welding work area to avoid continued exposure to the welding light and prevent further injury. 2. Rinse the affected area under running water to reduce thermal damage to the skin. Use lukewarm water—avoid water that is too cold or too hot. 3. Gently clean the wound with a disinfectant such as normal saline or iodophor to remove surface dirt and bacteria, reducing the risk of infection. 4. Apply a cold compress using ice packs or a cold, damp towel to help relieve pain and swelling. Avoid placing ice directly on the skin to prevent frostbite. 5. As advised by a doctor, apply topical ointments such as silver sulfadiazine or erythromycin to help prevent infection, relieve pain, and promote skin healing.
