LOX instead of CO2?

Does anyone know if is it possible/wise to use Liquid Oxygen instead of CO2 in an air tank? I have access to LOX at work and their isn't a single place on the island to get my CO2 tank filled, so I was thinking, CO2 is liquid in the tank, oxygen is liquid in the tank, why not right?

CO2 = not flammable
Oxygen = BOOM!!!

..I wouldnt mess with it (well, I would, but not for this type of usage)

Yeah.. Id hate to see you blow your jeep up (its kinda cool-looking), or yourself for that matter.

Well should either one leak, your options are either C02 asphyxiation or a sudden boom. Both are likely to be painless ways to go... go with the cheaper one haha

High pressure oxygen is very dangerous (flammable) around greases and oils :shock:

. Go with CO2 or nitrogen.

I heard a story from a fire training about guys using propane (cuz they had propane tanks on their farm trucks) to fill tires. One truck caught on fire and when the tires blew, it flipped the truck upside down!

Propane is a good refrigerant, so back when r12 went off the market people started refilling the systems with propane.......hehehe

Why would anyone want to fill up a system of pipes that go through their house and contain a flammable gas heavier than air in a coil above their furnace so when the leak happens they get a heavy flammable gas cloud heading to their pilot flame? :shock:

WOW. No wonder people have bad accidents.

Lox would not be a good decision. As a cryogenic liquid it would need to be refrigerated to -297degF. If it warm to -235degF it turns into a gas and expanding by a factor of 800.
Oxygen is a "NONE FLAMABLE GAS" it is an oxidizer and will cause an increased/accelerated burn rate. E.G. Acetylene torch, the Acetylene is the fuel the Oxygen makes it hotter.

LOX instead of CO2?
