CO2 Tank Overfill?

[PlanetX]

I went to get my 5# CO2 tank filled today. When I got it back, the guy told me that he put 5.5# in it.

Is this even possible?

If it is possible, is it safe?

Should I purge some CO2 out of it before I hook it up to my regulator?

You're probably ok and won't have to do anything special.

don't leave it in the sun, don't wash it in warm water...

The Tare weight is stamped on the cylinder near the neck.
Weigh the tank and see what's what.

fwiw, I routinely do a couple of short blasts before screwing on a regulator just to eliminate any CO2 droplets from the fill (which do crazy stuff to regulators)...

Cheers!

A cold cylinder can hold more than a warm cylinder. I doubt they'd have problems filling a 5 lb cylinder in summer however without having a method to keep a bigger tank cold you'd be getting less than a full tank for something like a 20lb on a hot summer day in my experience with filling tanks with gas.
