A fire extinguisher!! I needed mine yesterday while welding up a weight bracket. I have a supply of clean shop rags and towels way in the back under the bench, , and a strange light appeared in the corner of my field of view. The welding stopped and i saw the ugly yellow flames! A grab for the extinguisher and went to pull the pin, it would not come out! For shipping reasons it was zip tied in place!! Thoughts of my garage shot through my head as I grabbed a pair of pliers to rip the pin from the trigger. Hit the flames at the base and choked and gagged on the smoke and powder in the air! Garage saved!!!
