Article in English: If you've just burned yourself, rinse the burn under cool water. Cold water will quickly cool the affected area and minimize the size of the burn. Don't use soap yet, just rinse the burn.  Don't rinse chemical burns or more serious burns. If you see any scorching or ash and smell burning, stay away from water and call 911. Don't submerge burns in water. Rinse gently, then dry your skin by patting it with a clean towel afterward. After cooling down your skin with water, you can use a clean cool compress on the burn to reduce swelling. This helps to soothe the pain and minimize the swelling and blistering that can occur with minor burns.  Cool compresses will only cool the burn for the first 10 minutes after injury. After that point, a compress may relieve pain, but it won't treat the burn. Do not use chipped ice cubes, bags of frozen vegetables, or other frozen items instead of a clean cool compress. Burns can numb your heat-sensitivity, which means you can actually get frostbite. Even if you think the burn is relatively mild, keep an eye on it to make sure it doesn't get worse. Sometimes, bad burns can become numb, making the pain come on later. Learn the difference between burns to plan for care:   First degree burns affect the top layer of skin only, and are characterized by redness, minor swelling, and pain. First degree burns don't usually require medical attention.   Second degree burns also only affect the outer layer of skin, but are more severe, characterized by red and white splotchy skin, blistering, swelling, and more significant pain.  Third degree burns affect the under layers of skin, and the fat beneath. Some severe third degree burns even affect muscle, or bone. These burns are characterized by blackness or white scorching on the skin, and may be accompanied by difficulty breathing, severe pain, and smoke inhalation. Use a cold washcloth or other sanitary compress on the affected area to help with the pain. Coldness helps both to reduce the pain and reduce the swelling of the burned area....
