If you get burnt, put your hand or the limb you burnt in cold water for at least 15 minutes.
This isnt strictly correct. When you burn yourself, the skin continues to cook (like chicken
) after the hot metal/object has been moved away. So, running under cold water immediately is recommended, but it only works if you do it IMMEDIATELY and only for about 20 to 30 seconds - any longer than 30 seconds is pointless as you have already cooled the area to stop it burning and if its under water for 15 mins, you cant cling-film it so you'll get a blister.
Run under water for 20 to 30 seconds, Just to cool the area and prevent the skin from burning more. Then wrap the area in cling flim, then leave for an hour. When you take the film off, there will be no blister and a minimal burned area.
BTW, this isnt just for soldering burns, its for any burns. Try it next time you have an accident involving skin + heat.
