For a practical example of "cause and effect" and to offer some professional example to illustrate the effect of both explosive decompression, the resultant hypoxic cabin atmosphere, with measured internal systems damage, and a resultant rapid depletion or remaining flight crew oxygen reserve.
You only have to consider a simple 10 litre oxygen flight crew reserve cylinder at 150 bar pressure exiting through the aircraft skin with the equal and opposite reaction of the cylinder valve exiting up into the passenger cabin causing additional damage and the required decompression leak path.
If in addition the oxygen release were to act with an ignition event, the "fire triangle" of adiabatic heat with a fuel source (metal material etc ) together with the oxygen acting as a fuel you have the basics of an oxygen plasma fire.
The photos below illustrate this with Boeing 747-482 (VH-OJK) Manila Philippines 25 July 2008 just the mechanical explosive damage without a resultant fire of one of the high pressure oxygen reserve cylinders in the forward hold section of the B747
If of interest detail and engineering can be discussed in detail but it does illustrate clearly causation effect.
