I'm guessing because concentrated O2 is extremely flammable and would be fuel for a fire, when the opposite would be needed. Rapid fire-suppressant systems basically work by sucking all of the oxygen from the room/space as quickly as possible.
- bdonlan 13y agoThe flight deck O2 masks are specifically designed to provide positive pressure to avoid smoke inhalation in the event of a fire. There's no real reason not to use them - if the fire is close enough that it would matter you're already dead.
- nlh 13y agoMakes sense to me. Thanks for clarification.
- KMag 13y agoO2 isn't flammable and doesn't provide fuel unless the oxidant is something very electronegative like fluorine. In most fires, oxygen is the oxidizer, not the fuel.
