Initial report suggest it’s a battery fire in the luggage stored in overhead compartment
Also reports says the FA told passengers to stay put (seat belt on as they were about to push off) when they tried to put out the fire with a fire extinguisher, and that:
1. The order to evacuate wasn’t from the pilot or FA, but pushed by pax fleeing from the back of the cabin (one of the emergency door was open by pax while the other by a FA)
2. Until the pax were moving forward, the other pax in the front of the plane weren’t even aware of the fire
Several pax were unhappy the lack of coordination from FA and pilot control, including reminder of not taking bags when evacuating (definitely not the textbook exercise seen on the Japanese incident 12 months prior with flight 516)
A novice question for those who worked on commercial planes:, a usual order of business when there is a fire found in a building is to remove or isolate burning item or room, alert, contain and evacuate/extinguish, Any difference for a fire on pax planes?
