Get a ABC fire extinguisher. I'd recommend getting a 5 pound one. While some contests accept one of those smaller 2 1/2# Sentry's. Most will require a 5# one for the length of the blast. They want to make sure fires are out.. I believe that Home Depot's have the larger one's. Keep your receipt for it. That will show that it is up-to-date. I found out that those big box stores like to buy them and hold them. Mine was over 1 year old when I bought mine from the stamp on the bottom of it.
