An employee was tracing an electrical conduit through a partition wall in preparation to demolish the conduit. The employee passed through an access opening in the partition wall and entered an area concealed behind the wall. Upon setting his feet down on what appeared to be a concrete floor, the surface gave way and the employee fell approximately 15 feet to the floor below sustaining a fractured tailbone. The surface that gave way was later determined to be sheet metal that had been covered over by dust, and was not a structural floor.
