In a word: ALOT
Don't forget that a fire extinguisher is a pressurized container. If there's some major failure of the container, you wind up with a hell of a lot of pressure escaping in a very short period of time. Similarly if the plane experiences a pressure loss, the relative pressure differential between the contents of the extinguisher and the outside environ ment will increas eand the result is the same. To the laypeople this is known as an explosion.
I doubt any airline would allow a passenger to bring any pressurized containers on board. too much of a risk.
