CO2 tank in hot car

My wife is going to pick up my CO2 tank at the place
where I left it for inspection and refill. Then she'll
have to leave the tank in her car for the afternoon.
The car will be sitting in the hot Texas sun (which is
bigger than anyone else's sun) for several hours. I don't
suppose the internal temp of the car will top 140 degrees.

Does anyone know if this will be dangerous?

Could be enough to get interesting with a full fill, I guess - the graph
seems to imply that if not overfilled, 120F would be fine:

Couple of ice packs and a blanket? If a small tank, a cooler that it
will fit in would beat the blanket, but a blanket would help with a tank
that won't fit in a cooler.

I really have no idea, but the above scenario makes me nervous!
Personally I'd be uncomfortable with the whole thing.

Probably it's OK: these things do get trucked around and I'm sure they
get exposed to considerable heat. But hopefully someone who knows what
they're talking about can chime in.

One thing: If you do this, make sure the tank stays upright.

But seriously, if no one has any solid advice here, I'd attempt to talk
to someone who would know (maybe someone at a local beverage shop or
even a fire extinguisher shop: those guys handle CO2 all the time and
they'd know the safety issues).

Any temperature above 120 F. (2000 psi) will likely blow the safety
valve.
CGA (compressed gas association) recommends not to exceed 120F.

Maybe she could put it in the trunk...no windows to let the sun in.
Probably no better if your car happens to be black or a very dark color...

Give the guys at the fill shop a call and ask them...they should know
for sure...

If the safety valve does blow, make sure you fully ventilate your car before
trying to drive away!

Good advice, if it blows while she is driving it will most likely
scare the hell out of her.

And possibly fill up the car with CO2 in a very big hurry. That could
be dangerous.

The tanks can be placed on their side with no problems but should not
be put in service that way.

Yes - it would be very dangerous. I suspect it would knock one
unconscious in very short order. I live close to a wine region, and
periodically wine makers die because they get a big whiff of CO2 from
the fermenters and it knocks them out: they either collapse in the tank
or somewhere that is saturated with CO2 and asphyxiate.

CO2 is much more dangerous than you might expect.

I got a breath full one time and it burned my throat and lungs
something terrible. Fortunately I took my head from the source and was
able to breathe clean air after one breath. It was not a pleasant
experience. I will never stick my head in a fermenting vat again.

I got that same feeling once bending over a chest freezer I was using as a
fermenter holder. I tried lowering a lit match into the freezer. It immediately
went out.

Nasty wasn't itOn Mon, 26 Sep 2011 13:27:36 -0700, "Bob F"
Nasty wasn't it? Imagine if you couldn't get to fresh air.
In the context of the original discussion, the OP's wife could be in a
real bad situation if the full tank vented into the car while she was
in it.

CO2 is heavy and collects in vats. Confined spaces are particularly
dangerous. Some people have the money to make a vineyard, but not the
training or common sense to safely operate same.

She'd either be dead from asphyxiation, dead from the pursuant car crash, or
just some bad experience from passing out while driving and ensuing
consequences.

It would seem that driving with the window open would prevent most of that.

No worries. I've arranged to have my mother-in-law
pick up the cylinder.

It is not subtle. When the blow out plug lets go, you will know it. See

Assuming no traffic stops. Not a good plan. It's why welding company
trucks have open backs and why larger shipments use closed box trucks
that have special ventilation that is not near the cab.
