#9 Plastic Wrap
Though it may seem too simple to be true, plastic wrap is used by professionals in treating burns. It won’t melt, it sticks only to itself, and contains no harmful chemicals, making it effective in treating thermal burns until emergency help arrives. It works so well, in fact, that most ambulances keep a roll on hand.
Simply wrap it around the burn, securing it either to itself or applying a bandage of some sort on top.
