co2 hydro test / refill

[elmito]

I had to have my 5lbs CO2 tank hydro tested and the same shop said they could also refill it. I mentioned it was a CO2 tank multiple times and I know gas tanks have certain fittings according to the type of gas its meant to hold.

Here's my probably a dumb question moment. On the invoice it says "5 lbs Jetliner Recharge," i'm assuming its just another term for CO2 refill. The guy at the shop even asked me if its for a kegerator.

I'm probably just being paranoid but I don't want to poison myself and my buddies later tonight.

Considering CO2 is the only gas that is going to dissolve in beer (CO2 combines with water to form carbonic acid)...if it carbonates, it is CO2

No worries. They guys who refilled it knew it was a CO2 bottle.
