The source of the smoke was determined to be a “malfunctioning air handler” in Nordstrom, which is now being shut down, according to scanner traffic. Most of the fire vehicles are expected to leave the scene shortly.
Firefighters from Arlington and neighboring jurisdictions are investigating smoke and a burning odor in the Pentagon City mall.
The smoke and odor were reported on the Nordstrom end of the mall. Thus far firefighters have not found a fire.
A large emergency response is on scene, with firefighters checking out all floors of the store, as well as the Metro station and the roof, for a smoke source.
