Dollar General has again been found in violation of federal workplace safety regulations for “willfully exposing” staff to fire hazards at a Pennsylvania store, the Department of Labor said Friday.

Investigators found “dangerous safety hazards,” including blocked emergency exit routes and electrical panels, at a Jersey Shore, Pennsylvania, store during a November inspection that was sparked by a complaint made to the Occupational Safety and Health Administration.

The hazards were similar to violations found at other stores operated by the discounter throughout the U.S., and the inspection is one of more than 180 investigations in which OSHA has found Dollar General to be jeopardizing worker safety, the DOL said.
