Montgomery County firefighters are on the scene to investigate a report of smoke at 4520 Willard Avenue in Chevy Chase. The first firefighter to radio from the scene reported "black smoke" rising from the building. Minutes later, another firefighter said he could see "light smoke," but that it was not necessarily fire-related. "It's dissipating very quickly," he radioed. "It could be steam of some sort.
Moments later, firefighters searching the building said they had not yet encountered a fire. Upon reaching the roof, one reported the team assigned to that level had shut down "the unit." The building maintenance engineer will restart two units to attempt to confirm there is no smoke or fire issue, once the rest of the building is swept by teams.
Alarm system inspection showed no alarms had been triggered by smoke or fire anywhere in the building. All other fire units not needed to assist the maintenance man are being put back into service.
