How to treat fireworks burns?

Standard First Aid Five Steps Flush: Rinse with cold water for 15-30 minutes. Immediately place the burned area under running lukewarm tap water to rapidly cool the local area, stop heat damage to the skin, and reduce risks of redness, blisters, and scarring. Note: Use only lukewarm tap water; do not apply ice or ice cubes directly to avoid secondary frostbite. Remove: Gently remove clothing and jewelry from the burned area. Carefully take off clothes, rings, bracelets, watches, etc., near the wound. If clothing adheres to the skin, do not forcibly tear it off; cut around the fabric and leave the adhered part for doctors to handle. Soak: Cold water soak to relieve pain and swelling. After rinsing, if the burn area is small, continue soaking in cold water for 10-20 minutes to relieve pain and reduce skin damage depth. Avoid prolonged soaking for large-area burns or for children and elderly to prevent hypothermia. Cover: Protect the wound with sterile dressing. After cooling, gently cover the wound with sterile gauze or clean medical plastic wrap; if no medical dressing is available, use a clean, dry cotton towel. This isolates dust and bacteria, prevents infection, and reduces pain from contact. Send: Take severe burns to the hospital immediately. For deep burns, large-area burns, eye injuries, critical areas like hands and face, or severely contaminated wounds, seek immediate care at the burn department or emergency room after basic first aid.
