Narrative:

Taxiing aircraft and smelled something burning. Stopped aircraft on taxiway. Smell became worse. Smoke began to come out of the instrument panel. We notified tower to send the equipment. Turned off both engine generators. Captain verbally briefed flight attendant to evacuate/evacuation aircraft both forward and aft position. Both engines were shut down. Emergency power was switched on. We then ran the emergency checklist. Smoke dissipated. Evacuate/evacuation proceeded normal. Outcome: 4 injured. Note: only forward 2 slides deployed. Aft slides were not deployed. The flight attendants in the rear were not aware of what was taking place and did not deploy rear chutes. With all power off the aircraft, the PA will not work until emergency power is turned on. So the rear flight attendants did not get the word. Because the smoke had dissipated and the evacuate/evacuation was proceeding normally, I did not go to the rear of the aircraft and was not aware only the forward 2 chutes were deployed and not the aft. Supplemental information from acn 190729: taxiing for takeoff on taxiway north (runway in use 22R) smelled smoke then shortly thereafter smoke visibly coming from instrument panel. Stopped aircraft (shut off generators, electrical fire). Smoke continued. Opened cockpit door. Told flight attendant we need to evacuate/evacuation the people. Told flight attendant he could use front and rear exits. Performed emergency evacuate/evacuation checklist. Did not give 'easy victor, easy victor' call. Did not want that feeling in air -- gives feeling of 'run for your life'. When it came time in checklist for that command, smoke had leveled off and flight attendant had things going very nicely. Emergency power had been off briefly (1 min). Between talking to flight attendant and turning emergency power on, evacuate/evacuation checklist, at that short time flight attendant could not communication with back end flight attendants. I did not peruse problem because things were going nicely. Only front 2 slides were used as result. 1 woman broke leg. 1 hurt ankle. Entire crew, including dead heading flight attendants who were assisting, were drug tested. No reason for this. This treatment was abusive. When we had reported for duty at xx am that morning for an xa am takeoff, we were exhausted and finally got to a hotel at XXXX.
