Compressed Gas Cylinder Safety
 

In a related note to the current trhead on liquid oxygen, does anyone
still have the link that was posted here a year or so back on a goofy
compressed gas cylinder stunt as described below...

Some guys took a big 600 (?) psi carbon dioxide cylinder, laid it down
on it's side, one got onto it, and another knocked off the valve. The
cylinder, with it's rider, took off horizontally for 100 feet or so,
then crashed into a huge bin full of tomatos. One GRAND mess! Obviously
'staged' but still impressive, and quite funny!

I though I'd saved this link, or the mpg file, but now I can't find it.

Thanks,

I think that's closer to 1600 psi.


I tolerance everything and tolerate everyone.
I love: Dona, Jeff, Kim, Kimmie, Mom, Neelix, Tasha, and Teri, alphabetically.
I drive: A double-step Thunderbolt with 657% range.
I fight terrorism by: Using less gasoline.

CO2 is stored as a liquid. It's vapor pressure at room temperature is
around 800 psi. Bob

Nope.

Wups. I was thinking of the critical pressure, which occurs at a
temperature above ambient.

I worked in Lamont Observatory when I was a kid,
-- back in the halcion '60s -- as an electronics tech.

One day [[ thank GOD!! it was a Saturday ]] someone
knocked over a large tank (4' or 5' job - this is 30-odd
years back, so it's a bit fuzzy). I don't know if it was
oxy or acetylene or what, but it made everybody on site
re-check their tank moorings.

I think the tank was in the old machine shop ... anyway,
over it went; top came off; and it proceeded to carve a
hole in the stone wall of the shop. Skittered out down
the observatory road for a few hundred yards before it
encountered something less mobile than a (somewhat dated)
stone foundation wall.

HECK of a mess. The university (Columbia) counted its
blessings that nobody was killed that day.

I was Chief Engineer at A brewery in the Fiji Islands in the seventies.
Among other things we tested and filled our own CO2 bottles. We had a
sequence of events that were almost impossible to believe. A non-return
valve leaked and allowed 300 psi Co2 into the low pressure collection
system,which was shut down at the time. A vent valve was supposed to be
opened when the plant stopped but that was overlooked. The pressure built up
in a low pressure scrubber and blew off the inspection cover which was held
on with 6 mm bolts. These failed in tension and the cover flew across the
shop and knocked over a couple of full CO2 cylinders. One of the valves
broke off, and the cylinder bounced around a bit but didn't really do any
damage. The valve went out through the galvanized steel roof. At the same
time, all the ceramic saddle packing from the scrubber flew all over the
place and caused a hell of a mess. There was only an engine room operator on
duty at the time and luckily he was at the other end of the plant. He had no
idea what had happened and was an incoherent mess when he called me at 3:00
AM. It took me about 4 hours to figure out what had happened.
I came to the conclusion that the reason the cylinder didn't move faster was
that the valve that broke off the cylinder was only about 7 mm in the bore
and this limited the amount of gas that could escape.

I finally found the URL, it's:

I didn't recall it quite right, the guy straps the cylinder on his back,
and it looks like oranges instead of tomatoes. Anyway, it's a mess.

So who held the guy's beer?
