City firefighters today extinguished a small fire on the top floor at the north end of the B&O Warehouse, the red brick structure just beyond right field at Oriole Park at Camden Yards.
About 100 people were evacuated from the eight-story structure as a precaution. No injuries were reported. Oriole offices are in that end of the warehouse.
Fire officials said a welder accidentally ignited some material with his torch about 11 a.m. while working on an eighth-floor elevator.
