Put it in a bucket of ice water for a like 25 minutes. That what we would do in welding class if someone burnt there hands. He also had some kinda burn creme to but i cant remember what it was called.
I burnt my hand really badly at work last week, and what I did was run it under cold water for 20 minutes and then I put burn gel on it (aloe does the best job) .Keep a cold cloth with you and put it on top of the gel and the burn and it will feel 100% better.
