It is kind of funny when folks say "Situation was bought under control so passengers can use ES and no need for slide evac".
Imagine a scenario where everyone lined up with their cabin baggage to use ES and fire restarts.
There is no evidence the leak and ignition sources were identified and fixed.
Fire tenders have no more fire retardants left in their tanks.
Door (or doors) are probably disarmed.
It would have been a major disaster if fire restarts.
Bottom line, don't play with fire (first/third/old/new worlds doesn't matter). Evac pax even with one slide and move pax as far way from the fire, doesn't matter what fire crew is doing.
BA@LAS or DY@FLL, saving pax is priority not metal.
