Narrative:

On taxi in, after land checklist complete, disturbance heard in back of aircraft. At the same time first flight attendant reported smoke in cabin. Concurrent with this announcement smoke/vapors began entering the cockpit through the air-conditioning system. The cockpit door was open so we both looked back and saw dense smoke/vapor in passenger cabin. The captain immediately stopped the aircraft and initiated the evacuate/evacuation. I noticed the left hydraulic quantity reading zero. I called sfo ground and said 'flight XXX evacing aircraft, smoke in cabin.' the captain then called for the evacuate/evacuation checklist, and we accomplished it. Crew and passenger all had symptoms from smoke/vapor inhalation and there were some minor evacuate/evacuation injuries. At the time the left engine and APU were running. The source of the vapor was a failed hydraulic line in the aft compartment. The fluid was drawn into the air- conditioning system by the APU. Callback conversation with reporter revealed the following information: the reporter stated this smoke and vapor in the cabin is a second time incident for this aircraft and one other aircraft in the fleet also experienced the failed hydraulic line allowing fluid to enter the APU pneumatic system. The reporter said the flight attendants were treated for the toxic vapor. The reporter stated the air carrier is working up a fix to correct these 2 aircraft.
