SUMMARY

This discussion centers on the behavior of oxygen tanks during explosions, specifically how they rupture and the dynamics of the resulting flames. Oxygen tanks typically do not explode in a traditional sense; instead, they may rupture due to mechanical failures or excessive heat, leading to the release of oxygen which can ignite if a fuel source is present. The discussion highlights the importance of understanding the fire triangle—oxygen, fuel, and heat—and notes that oxygen itself is not flammable. Videos of oxygen tank explosions can be found on platforms like YouTube, but they often do not capture the detailed dynamics of the explosion.

PREREQUISITES
  • Understanding of the fire triangle: oxygen, fuel, and heat
  • Knowledge of mechanical failure modes in pressurized tanks
  • Familiarity with the concept of fusible plugs in gas tanks
  • Basic principles of combustion and explosion dynamics
NEXT STEPS
  • Research the mechanics of oxygen tank ruptures and the role of fusible plugs
  • Explore the differences between oxygen tank explosions and LPG tank explosions
  • Study the principles of BLEVE (Boiling Liquid Expanding Vapor Explosion) in relation to gas tanks
  • Watch educational videos on combustion dynamics and explosion behavior from reputable sources
USEFUL FOR

This discussion is beneficial for safety engineers, emergency responders, and anyone involved in the handling or storage of pressurized gas tanks, particularly those interested in understanding explosion dynamics and safety protocols.

I can't find anywhere direct videos of exploding oxygen tanks. Have you seen one? How does it explode? Does the tank disintegrates into smithereens like a sidewinder missile? Or does the cap blows off and the oxygen tanks becoming projectiles? And how do the exploding flames behave? The tank becomes a inferno exploding in all directions all the stored oxygen or the top spewing off flames and igniting just the released oxygen?

Or just share some actual videos of exploding oxygen tanks (in lab demonstration or real). Thank you.

If you go to youtube and enter "exploding oxygen tanks" you get pages and pages of them. What do you want that these don't provide?

I have my EMT O2 tank that I can sell you and a hammer that I can loan you. You will need to set up your own video camera, and leave me instructions for where to post your last YouTube video. :wink:

The tank will split along the bottle since, with increasing internal pressure, the hoop tension is twice the axial tension.

Oxygen is the oxidiser, there must also be a fuel, only then can you get a flame.

Oxygen tanks burst when subjected to high temperature during fires. The release of oxygen will then increase the rate of reaction, and so increase the rate of heat release during the fire.

The oxygen tank should have a fusible plug that will blow out to relieve the internal pressure without splitting and exploding the tank during a fire.

I tried but all videos didn't actually show how the oxygen tanks explode (like angle of propagation of the debris in the tanks. I want to see exactly how the tanks behave or dynamics of its explosion).

Oxygen is not exactly flammable. The material of the tank however, usually is. So what can make any flash is the ignition of steel. From that on it looks (works) like a really violent cutting torch.
 
No single video of the actual tank exploding? Not even in universities educational aid?

Anyway. How does a propane tank or LPG (Liquified Petrolium Gas) tank explosion differ to oxygen tank explosion? I read news about LPG tank exploding when the contents leak out and collected at floor and touch something with flame. It is the contents that explode. How about in oxygen tank explosion? Is it also the leaked oxygen when collected outside that explodes? How do they differ in their explosion trigger or behavior? One is LPG tank, one is oxygen tank, so I can't imagine.

O2 is only one leg of the Fire Triangle. It needs fuel and heat to burn. When an O2 tank ruptures, it is due to a mechanical containment failure (tank out of Hydro and corroded or something), or due to a mechanical shock at a vulnerable point (like the valve getting hit as a tall tank falls over. If the pressurized tank is sitting in a fire for some reason, it can overpressure and rupture.

Tanks of flammable liquid like Propane or Gasoline are different. If they leak, that leakage can catch fire which heats up the tank and boils the flammable liquid inside, and given the right (wrong) condictions, can lead to a BLEVE...

What makes you think they all explode the same way? There may be several types of failures, and an infinite range of external circumstances.

Would you watch a single video of a car crash to make conclusions about car crashes?

What is it with “explosions”. Why do you read and imagine it so wrong. The fuel gas tank leaked into the enclosed space where the fuel was mixed with air containing oxygen. When the mix was ignited it exploded and set fire to what remained of the building.

The tank may then have been heated by the fire. The tank should have blown out the fusible plug and allowed the remaining contents to burn at a controlled rate. If that did not happen then the tank would be weakened by the heat, so the rising pressure would have suddenly split the wall causing a fireball. The tank would not fragment, a short straight line would simply rip through the sheet metal.

Neither tank should explode. The tank should release the contents at a controlled rate. The fuel gas would burn at a controlled rate as it mixed with air. The oxygen released would increase the heat generated by the existing local fire.

May i suggest that you go to the classic mythbusters episodes on exploding water heater tanks. Actually they had lots of slow mo explosions of everything. Not a lot of science but unparalleled television.
