BALTIMORE — Baltimore firefighters probably made record time arriving at the scene of a recent fire. That’s because it broke out in the building housing the fire department’s headquarters.

Fire department spokeswoman Blair Skinner told The Baltimore Sun that an electrical fire Thursday triggered the evacuation of the 85,000-square-foot downtown building the fire department shares with the city’s finance and information technology departments.

Skinner says firefighters responded in a matter of minutes, in addition to the fire chiefs already in the building.

She says the smoke appeared to have originated on one of the floors above the fire department’s offices.

No one was injured. The exact origin is still under investigation.
