1 Fire extinguisher and a first aid kit plus lots of duct tape.

I was grinding on a exo-cage for a Jeep that I had welded up. I sat the grinder down to get a closer look. Needless to say the grinder had not stopped until I stopped it with my thumb. Almost took the thumb off. All I have was duct tape and tissue paper. I grabbed the TP and wrapped my hand. the blood was making a mess. I then wrapped my hand as tight as I could with the duct tap. I knew it needed a doc to look at it, but I wasn't going to leave that mess in my garage. So I grabbed some thinner and a couple shop towels and cleaned things up before the trip to the ER. Four staples and plenty of cuss words as they cleaned it out later, I was back home grinding on that cage.
