Default Well Keith

I looked at all those pics, and he is one lucky boy, to have come through that. Amazing to me that it just exploded, but nothing seems burnt. The air accetylene mix must have been just right.
The steering wheel is all bent. I guess the blast pushed his body onto it.
We used to set off the odd acetylene bomb at the workshop in singapore.
We used small milk cartons Probably only 250 or 300ml, and they went with a good bang.
I remember hearing about a massive explosion in France years ago. It was set off, by a fireman turning OFF a light.

Default Good Cautionary Tale

Good Cautionary Tale, and a very lucky boy, glad he live to tell the tale.


Pictures and stories like this are a object lesson for us all, you can tell people not make sparks when they smell gas but something like this is a far more memorable lesson.

Cheers Phil

Dumbass probably laid the acetylene bottle down.....a no-no by all accounts.
Acetylene is always supposed to be transported upright, otherwise it leaks out past the valve in liquid form, gasifies and, well... you know.

Although you should keep acetylene bottles upright usually no damage is done laying them down. The problem arises if you draw off acetylene while the cylinder is lying down or shortly after standing it upright. This causes the asetone to be drawn off with the gas making the remaining contents unstable.
So Bob stand your cylinder up and don't draw off any gas for a fiew hours to give the asetone time to resettle. While we are talking safety never let any oxygen fittings become contaminated with oil, our teck teacher had a large poster in the welding room reading " oil + oxygen under pressure = BANG.
