CO2 Vs. Scuba tank?

We had these things in the orchard, on every truck that had a tool box. They were a backup for the refrigerant cylinders full of air.

Hey, what about one of those foot-operated pumps? Cheap and cheerful, and just think of the aerobic benefits!

Here's a bit of info about CO2 tanks. This is by experience, not by reading books...

First of all, CO2 at an avg temperature of 70F, changes state at apx

Secondly... If your Jeep's cab filled up with CO2, you would DEFINITELY know. It doesn't have a smell per se, but rather, it has an effect on your throat and nose. Remmeber when you drink a soda, and you "burp through your nose"? Well that's what inhaling CO2 feels like. It's not a fun thing. It's not particularly dangerous on the short term but you'd get very annoyed very quickly!

As far as mounting ANY pressurized/liquified gas tank, I'd make sure to point the butt-end of the tank towards a safe direction, most likely towards the ground. Most accidents happen when the valve is knocked loose and pressure is lost through that valve, which creates a torpedo out of the tank, as someone pointed out.

Horizontal storage is "acceptable", though not preferred. However, usage of the tank MUST BE DONE horizontally, otherwise your regulator will be trying to depressurize liquid, and it doesn't like that too much ;)

JP PS: I am a homebrewer and I've used CO2 safely for about 10 years.

I think you meant "vertically" with the usage.

Homebrewer also. Jim

Very correct, I got my horizons crossed-up!

Usage should always be done while the tank is vertical (ie, upright), otherwise liquid CO2 may end up in the regulator.

gaseous O2 ain't much different Mike.

you don't wanna get oil/grease on your reg, hoses, torch valves, anything. And it's a good idea to have clean non-greasy gloves for torch work.
