thumb of michigan | Not really sure what happened other than the guy showed me a can of what he put in before switching over to 134a. He must have put the conversion fittings on after putting in the glider gas. It was not cooling and showed a low charge so I put in a couple cans in through the manifold gauges. Pressures were coming up and I picked up the can by the fitting on the top to feel how much was left in it when I heard the loudest bang i ever heard in my life. The bottom of the can blew out and put a hole in the bumper cover, the valve on the can tap tore open the palm of my hand just behind the first knuckle and chipped a piece of bone off and then tore upward in a spin and put a dent in a sheet of roofing steel in my shop. I assume there was some air in the system and it somehow combusted with the propane or else it was somehow a rapid chemical reaction, but nothing is for sure. After bandaging my hand I got a new pair of shorts and took the rest of the day off. I also refused to work on that vehicle again. Ever. | |
