a set Ilene explosion

I don't think anyone would argue that transporting acetylene in an enclosed vehicle has a risk to it. I'm not sure i see though how it is more dangerous than storing it in any enclosure. I'm not sure i see how it is more dangerous than homes using natural gas. Does it make a person think about hitting the garage door opener button when they come home? naaaa!

It should be common knowledge that transporting acetylene, propane, etc. in a closed vehicle is a no-no.

I would agree, though, that it is more dangerous. A car is typically a much smaller enclosed space than a garage, so the concentration is likely to be much higher for a given leak rate. Plus, there are far more cars running into each other than garages.

If I remember correctly, one of the things that make acetylene more dangerous is the range of concentrations where it will easily ignite (from 2.5% to 81%). With propane , if it's too lean or too rich it won't burn. Propane's range is from 2.1% to 10%

The biggest thing people tend to forget, is it will fill the trunk, van or seating area of a vehicle in short order. If you don't smell it. And light a cigarette, it will be a big boom. As when they use to sell the carbide cannons in the want ads of the magazines. Loud noise makers for holidays.
There are enough U tube vids of them going off and including the last one that the LWS acetylene plant filling dock and et al went up. In Marysville Mi.
the guy prepping the cylinders, for filling used a steel cap to beat on another to remove it. There was a leaking cylinder, and the steel against steel sparked. Luckily he wasn't killed or injured badly, they did loose the shop and plant.
The news video of tanks flying over the house across the street. And then splashing down in the St Clair river. where something to see.
D.O.T. regs say don't and yet people think they know better. I just hope they only take themselves out and not their or somebody else wife and or kids.
:eek:

Remember a couple of years ago when the filling plant in Dallas went up? The live video of bottles being shot WAYYYYYY up in the air and EVERYBODY staying back letting it burn itself out was impressive.

just for those garage people, there are acetylene warning units-they detect the gas and sound an alarm.
i believe acetylene is heavier than air, right?
in most garages, it would run out under the doors, and down the floor drain if they have one.
but really, to prevent gas buildup, just run a vent fan at all times if gas is in there, it will keep the concentration down if there is a leak
