Naturally the decision to evacuate was sensible.
Alas in my experience the call "hazard on xxx side" seems to have been written out of the manuals for some obscure reason (lawyers?).
So whilst it's reasonable to throw them down the slides, is it reasonable to allow or encourage some to arrive straight into the source of the problem, be it burning baggage conveyors or smoking/burning brakes?
All I'm hoping for is some considered thought in a rapidly changing situation and not the mentality of "Someone said FIRE, so I was justified in calling evacuation!"
