Continuing the Delta 1961 narrative from the chart you posted:
The ramp personnel assisted several passengers off of the wings while other passengers returned to the cabin and exited the boarding door. During the deplaning, it was determined that a passenger bag in an overhead bin at row 13 was on fire. Flight attendants used a halon and a water fire extinguisher in the bin and the fire extinguished. Aircraft rescue and firefighting (ARFF) personnel arrived and inspected the aircraft and confirmed that the fire was out. Law enforcement met the aircraft and examined the contents of the bag, which contained two laptops, a projector, and an extension cord. Additionally, a small plastic lighter was found in the overhead bin; the lighter was observed to be melted. Law enforcement released the passenger bag and contents to Delta and it will be secured in quarantine. At this time, injuries have been reported, but the specifics are unknown
Thanks for posting this battery hazmat chart, there are certainly some recurring themes in the incidents!
I'd sure not hesitate to open an overwing exit as a pax if we had heavy cabin smoke on the ground.
