I suppose maybe the difference is in volume? I'd expect your system is sort of like what the weapons bays on a carrier had......though that is probably a little more extreme. I remember my squadron Gunner (the ground officer who managed the ordnance personnel) claiming that this system would suffocate a person in less than something like a second or two if they were unlucky enough to be locked in the vault when it was activated. Ooof

Volume would make sense. The flightdeck and supernumerary area are kept at a higher pressure to make sure my farts in the bunk don't make it forward. And to keep smoke out.

Just curious, do ANY of these rampers know how to use a flightline fire extinguisher? They are located on the ramp under nearly every jetway, ranging from 150lb units to 300lb units. These kinds of situations are the exact reason they are located there. Why have them at all, if personnel are either not trained how to use them, or simply don’t use them, but instead run around in a disorganized manner and accomplishing nothing?

I feel like that needs Benny Hill music

The small halon extinguishers aboard an airliner with its large cabin and air recirculation, don’t create enough density to be an issue, as long as you’re not directly breathing in the stream. Additionally, halon acts so fast, not a lot would be used in the course of a small fire, especially electrical fires. What the lousy thing was, was the removal of the requirement for water fire extinguishers from airliners. They are useful for a number of things. The large halon or halotron flight line fire extinguishers are great for engine and fuel fires also.

that was a regulatory change? we still have them on the narrowbodies

As in not required. They can still be there, but some places have removed them. But they have a good use still.

The thing I see here is that the door was already open with the jetway connected. That means the doors were disarmed so they had to be armed again before opening and deploying the slides. There were also probably bags already in the aisle as people would have already jumped up and started taking their bags down. Could be they couldn't get around them to go forward so someone made the decision to go out the back and the wing exits. Doesn't look like any rampers stuck around to tell the flight crew what was going on so all they probably saw was people running and then smoke.
