    Default Speaking Of the Hazards of Compressed Air Tanks

    Don't do this [shoot an oxygen tank]

    Morons.

    TL;DR — They put a large oxygen tank (full) into a safe. And then shot it with a caliber .50 BMG armor-piercing "incendiary" round. At fairly close range. You can imagine what happens after that.

    This is the short version:

    Long version (scrub to about 5:00 minutes for the good part).

    That wasn't a safe, it was a metal cabinet. 14 gauge wall thickness, maybe 16 . . . ? I could cut through it with a jig or circular saw and a metal blade in less than a minute. And dat .50 cal!!!! Merica!

    Armor piercing round?
    Note the the exit "wound" is larger than the entry allowing the compressed gas to escape on the off side, driving everything (except the bullet) towards the shooter.

    Impressive, but keep in mind that compressed air, as found in your air compressor's tank, is usually filled to around 125 psi, if that, on a single stage compressor, and around 175 psi on a two stage compressor.
    An oxygen tank, on the other hand, is usually filled to around 2000 psi.
    When compared to a typical oxygen tank, the pressure in your air compressor tank is rather lame.

    Yes. But there are a lot of people who misunderestimate (thanks, Shrub!) just how much energy is/can be stored in a pressure bottle.

    That was an oxygen cylinder (an 'E' [?] ) - an F tank of compressed gas WILL travel through several concrete block walls, if the valve happens to get knocked off .

    Because I deal with compressed Co2 and Nitrogen on a weekly basis, work sent me to a class on safe handling of those cylinders. The damage they can do is impressive!

    A freshly filled oxygen tank is at a little over 3,000 PSI - as is an aluminum scuba tank.

    A friend, while loading oxygen tanks onto a destroyer, had one fall out of the net, then it knocked off the valve on the side of the ship while falling, & it ended up on a beach over a mile away. The pressures are dangerous!

    My old man was the personnel manager, and safety officer, for Johns-Manville, back in the early sixties at their plant in LA. He told the story of this huge pressure chamber they used for production or testing of products. They made, back then, things like water mains and sewer lines for cities. He told the story of when he had to go see the site of a bad industrial accident involving the pressure chamber. This thing was large enough to put stacks of the big pipes inside, and had a massive big pressure door with a wheel lock like you see in submarine movies. Outside the door was the pressure gauge and a log to sign, and big warnings about waiting for the pressure to abate all the way after opening the valve before opening the door. The report indicated that there was still pressure when a new guy ignored the warning and opened the door, and the force slammed the heavy door open, crushing the guy, and killing him. My old man asked the tech supervisor in the plant why it would do that since the pressure reading was relatively small. The PSI wasn't very high but multiplied by the enormous volume under that pressure it was enough to blow open the heavy door with enough force to flatten the unfortunate tech.

    Geez, Paul, I used to have 2 actual .50 BMG machine guns _ mounted on tripods welded to the deck of my destroyer. The recoil of those was not to be believed. I can't even imagine the recoil of shooting a rifle with that cartridge, either prone or offhand.

    When I was a young sailor, I went with a friend to a gun shop and bought a Marlin 336C in caliber .30-30; the friend bought a .458 Winchester . We went to a range, where I fired a few shots, he fired 6 shots offhand , made his shoulder into hamburger, and promptly sold the rifle. ( He was only wearing a thin sportshirt. )

    It's like vacuum bagging. It's not the pressure differential. It's pressure differential multiplied by the surface area. A 3x6 foot door has a surface area of 2,592 square inches. With a 3 PSI pressure differential, that's 3 PSI * 2,592 square inches, which is 7,776 pounds of force working on that 3x6 foot door.

    My dad had a Marlin .444 Magnum lever action. It did have a recoil pad, I can tell you from experience that an afternoon at the range with that left you feeling like you'd spent the afternoon as Muhammad Ali's sparring target.
