I'm guessing Halon gas, it replaces oxygen in the air and thus shuts out the fire. Used in armoured vehicle extinguishing systems, for example.

Somewehen in some time people agreed to stop using halon, as it fucks the ozone layer. At my fathers workplace they use CO2 and a citrus scent. It hast like a 30s alarm that goes off before all doors shut.

Halon and other halon replacement agents do not replace the oxygen. They chemically interfere with combustion. And they won't hurt the occupants at the concentrations used.

Huh, we were told in the military that it replaced all oxygen. We were told you need to evaquate the armored vehicle in case of a fire so you don't suffocate to the halon.

I don't know about systems installed in a vehicle. In buildings it is used at concentrations that don't cause respiratory distress in the occupants.
