I had a hood laying on the floor of the garage & was cleaning a bunch of grease off the backside of it with rags and carb cleaner. When it was done I had a pile of filthy rags and another of semi usable. Then I decided to weld up some holes. Well, the sparks jumped far enough to hit the really dirty ones & torched them off. I immediately grabbed the other pile to smother out the first pile. Now I had a very large pile of flaming rags. My first instinct was wrong so getting the hot-dogs out probably wouldn't have been a good idea either. Luckily my 3 1/2 brain cells kicked in and I grabbed the extinguisher and put it out. Just made a bunch of smoke, no damage (unless your a rag). Word of advise, Keep a fire extinguisher handy at all times. You never know when you'll need it. Some of the shows I go to require one in your possession to enter your car. A very wise rule in my opinion. This kinda blows the theory "The older you get, the wiser you get" out the window
