KRAIG - Had to laugh at the driver of the compressed gas cylinder truck, he took off across the center divider as soon as he got out of the truck. Something about a foot of reinforced concrete maybe being a bit safer than leaning on the frt fender of a car?
Really, ANY compressed gas cylinder is a bomb, whether it has oxygen, acetylene, CO2, argon, even compressed air in it.
My Uncle had a 1 HP air compressor, had a 15 or so gal. tank sitting in the corner of his garage along a common wall with his living room of his house, and the exterior garage wall... when it exploded. He never knew why they put drain valves on compressor tanks! It not only blew the exterior wall off the foundation, but blew the common wall off the foundation. I saw the tank after it blew up, was turned almost completely inside-out.
