The Washington-Reid Elementary School Annex on Route 234 near Dumfries was evacuated about 2:30 p.m.
From a press release:
The smell of smoke in a classroom at Washington Reid (K-1) (Pattie ES annex) caused staff to pull the fire alarm at dismissal. Buses were already on campus, so the children were loaded on the buses and sent home without their backpacks today (annex only). Pattie ES dismissal will be as usual. Parents are being informed. The Fire Dept. responded and gave the all clear to re-enter the building. The alarm was pulled by a staff member who smelled an odor caused by installation of an air conditioning unit on the roof.
Afterward, Saunders Middle School at 13557 Spriggs Road in Dale City was evacuated.
