Twisty looked on the tank it just says oxygen no%-this is what I know-Dont know what a copd is
What will make oxygen explode?
Nothing can make oxygen explode!
A faulty oxygen cylinder can explode, but that's not the fault of oxygen, any gas under pressure would cause a faulty cylinder to explode, but that happens without a spark or match!
Oxygen is the stuff that supports combustion, that is, makes other things burn. And if it makes something burn really really quickly, that will look like an explosion.
So if you mix oxygen and hydrogen together and add a spark there is an almighty bang - the hydrogen exploded!
So if you smoke a cigarette in pure oxygen, the cigarette will have a very large flame - the cigarette will appear to explode!
If you generate a spark in pure oxygen ALONE, you may detect a 'bleach' like smell which is ozone (oxygen is O2, ozone is O3). But there is no explosion! If the spark is a piece of hot metal (like off an emery wheel), the sparks will be brighter and 'die' quicker, but .... sorry .... no explosions!
Summary and bottom line - oxygen does not burn, things put in oxygen burn. Oxygen does not explode, faulty oxygen bottles will explode.
