Don't juggle close to other people. Certainly juggle well away from your fuel store. Keep a fire blanket on hand and preferably an extinguisher if you think other things may go up. If you get a burn, wash it gently and put a loose bandage over it to keep it clean. When you get into the light check it over, pick any bits out, clean it more carefully and bandage it without getting anything like cotton wool near it.
Burns go deep quickly and the heat has to be drawn out slowly.
It really takes a good long time to cool a burnt area. The powder can cause breathing problems and is bad on the eyes. I always have two volunteers, one to hold the blanket and one for the extinguisher. Brief them and have them repeat your instructions. All Rights Reserved.
