Welding ground...don't do this!

So true story. Again positive proof I am not the brightest bulb in the box. Repairing a anaerobic digester I was inside the confined space doing what we do. Needed to weld up some 316 stainless.
Think rotting organic matter to produce methane gas to produce electricity. Four gas meter cleared us to do the repair after required air changes and venting with fans still in place. so I dropped down inside the tank, a mere 107 degrees or so with about 1000% humidity. Long story short the bacteria got in my lungs. I knew what it was as I could taste it when I breathed. Got sicker than a dog next day so I mixed up a small batch of chlorine gas and huffed a bit of it! Instant repair! Killed all the bad bacteria and I knew my body would replace the good stuff. My wife and her sister the nurse went thru the roof at my stupidity. And yet it was a solid cure, and I was literally better within hours. Engineering 101 applied! Do not try this at home and yes looking back it was likely not very bright, but man o man was it effective!
That's HardCore Man!
