Abstract: On February 2, 2008, Employees at Eurasian Harbor, LLC dba Ruth's Chris Steak House were exposed to carbon monoxide. A malfunctioning boiler forced high pressure through a common flue duct blowing off the end cap of the exhaust duct on a gas fired boiler. Carbon monoxide leaked out of the flue exhaust into the mechanical control room and seeped into the adjacent room through cracks and seams in the cement walls. A Baltimore City Fire Department spokesman indicated that carbon monoxide levels at the scene measure 400 parts per million. Fourteen employees were transported to area hospitals for further evaluation and treatment for exposure to carbon monoxide and were later released.
