Looks to me like either vertical or horizontal is OK, judging by
paragraph (1).

Interesting. I was sure that upright was the only legal way. It does say
they need to be secure, and if the floor is not flat, in a rack of some
type.

Thanks for locating the site.

Then you listed: http://hazmat.dot.gov/files/gstomo.pdf

says vertical or horizontal.

That was for medical oygen, and is speaking directly to the situation where
the bus full of old people caught fire, and the oxygen cooked all of them.
Sad.

Interesting that I found all kinds of links about that situation.

Cryogenics look like they have to be vertical, however.

Because of the need for the relief valve to be in the vapor portion of the
tank, I believe. I think I read that if not vertical, the valve needs to be
in communication to the vapor, or something like that.

Off this subject a bit, but perhaps not too far off.

How is the investigation to the explosion at Scaled getting along? Any idea
when a report will be released?

I'm sure you are not allowed to say much, but I (an others) are interested
in seeing what caused the tragedy, and how it will be avoided in future
situations. I thought you might be able to at least say what the time table
for results is likely to be.

I hope things are going well, with the progress on the next version. Keep
on, keeping on!
