Not many Oxygen fires in flight or on the ground
It seems very few aviation accidents involve the crew oxygen system. The only ones I am aware of are Egypt Air 804 (where an O2 mask left in emergency mode caused an O2 rich atmosphere that was ignited by either a window heat short circuit or a pilot smoking). The Swissair 111 had an IFE fire which breached the high pressure system resulting in a cockpit blow torch.
Are there still many ground fires resulting from repressurising oxygen with dirty equipment etc or is this also a thing of the past.
Thanks
