WATCH: Camera captures moment pedestrians narrowly avoid building collapse

Security footage captured the moment a firetruck happened to drive by a collapsing building that barely missed two passersby in Washington, D.C.

The building, which was undergoing renovations and surrounded by a safety fence, suddenly fell apart Wednesday afternoon. Video shows two women, one pushing a walker, crossing by the building. When they get about halfway across the street, the structure suddenly starts to crumble, with the facade careening into the road.
