From my experience it’s never been a good idea to put any of those compressed air bottles near an open flame, so how would that work for fire extinguishers. Does the extinguish over power the compressed gases, or is it an entirely different kind of mechanism, and if so, how does that work?

It can be possible to make a fire worse by using the compressed gas from a fire extinguisher. For example if you have an oil fire and aim too low you might spread the oil around even more. This is one of the reasons why you should make sure to get the correct fire extinguisher for the type of fire you are fighting. Fire extinguishers are designed to prevent this from happening though. The pressure in them is not as high as it could have been. In addition they have a nozzle that is designed to slow down the material comming out and spread it around more. I have not heard of anyone having issues with their fire extinguisher which makes the fire worse. Even if it might spread the flames around a bit the extinguishing effects are much more powerful. The only problems I have heard of is when people try to use water to fight an oil fire instead of a proper fire exinguisher or a fire blanket.
