A muffled explosion was heard and flames were seen coming from the vent near seat 3D. The aircraft, being prepared for a flight to Edmonton, was evacuated as smoke filled the cabin. A mechanic had noted a low passenger oxygen generator control unit and replaced the oxygen generator cylinders. He then saw a white flash engulf the unit. Another 35 oxygen generator system leaks were found in Delta's fleet.
