On the pics of the cargo bay pointed to by bloxin there is also visible damage on the "nozzle end" of the exploded oxygen bottle. Of course this damage may be more a result of decompression than of the explosion itself.
On the other hand if the thread of the bottle fails, the outlet connector and the valve would give a pretty good projectile. Here is a picture of that potential projectile.
