Immediate Action: Ice or Frozen Bag of Peas or Fruits
What to do immediately for a burn? Place frozen peas or ice wrapped in a cloth and place it on your skin, until you're able to remove it without it burning — this helps prevent blistering. (I kept ice on my arm for several hours.) Make sure not to put it directly on your skin, otherwise you might develop frostbite in that area. If you’re able to place the burned area directly in cold water (like your hand for example), then that is probably the best option.
