Just before 13:00hrs, Engine Company 58 was dispatched to the unit block of Rockdale Road in Baltimore County for the reported gas leak in a structure. Engine 58-1 (D/C Shearer) responded and was first arriving. Engine 451 (Maryland Line) was also on-scene. An odor of gas was in the air, but no readings were detected on any gas meters. Crews operated for approximately 30 minutes ventilating the structure and evaluating the gas connection to the building before clearing the scene and returning to service.
