I will ultimately have my CO2 tank stored in a cold environment. Is there any issue storing in a hot garage?

No

I would say that may depend on how hot the garage gets.

When I got some tanks filled a couple years ago in mid-summer, the guy who filled them warned me not to leave them in the hot car.

I don't know if that's just an abundance of caution, but nevertheless they went right home and into my basement.

I was thinking it had to do more with losing volume faster.

If it gets too hot, much of the liquid can go to gas, then it can vent. Not a good thing.

Do a web search.

That's the issue.  A car in the sun can get over 110 quite easily.  My garage isn't that likely to get that hot.  I store my 20# tank in the garage.  The 5# tanks are kept cold since they're attached to kegs.

No problem in the garage in Michigan.

Stories about exploding pressure vessels circulate around at my work (heavy construction). I've seen plenty of pictures of trucks/SUVs with the back half ripped off.

Bumping this again to perhaps get more input...

I'm considering relocating my 5# CO2 tank to the outside of my kegerator due to space limitations inside of the kegerator.

My concern is that my garage gets very hot during the summer here in Florida. Is there any concern over the tank expanding, leaking, etc. from this?

[Joe Sr.]

Leaking?  No.  The gas will expand.  Depending on how hot it gets, it sounds like most people here don't think a garage would be a problem.

I've never checked, but I'm pretty sure that my garage gets over 110 on really hot days.

Of course, I've never worried about the acetylene tank out there, and that has never exploded.

Not "leaking" per se but the vapor will expand with temperature and once it reaches the set point of the PRV it will vent. At that point your primary concern is probably wasted CO2, but it also presents a legitimate safety concern because it's a single point of failure.

[flbrewer]

Single point of failure?

[a10t2]

If your one and only PRV is defective, obstructed, whatever, then boom.

[flbrewer]

Oh.
