Oxygen in the cabin is on 12 minutes oxygen generators. Flight deck has a separate system with bottled O2

I meant that the pilots would have used the oxygen available if they were in danger of losing consiousness from smoke on the flight deck. At that point the risk of fire intensifying from the use of an oxygen mask is low compared to dead pilots.
9M-MRO did not use oxygen generators for the passengers. It had the optional bottled system for the passengers.
