Nine Carroll County residents were hospitalized yesterday after a faulty -- and illegal -- kerosene space heater sent carbon monoxide wafting through their apartment building, leaving some gasping for air, authorities said.
One of the nine had a history of asthma and was treated at Maryland Shock Trauma Center.
Kerosene heaters are illegal in commercial structures or buildings with three or more apartments. But fire officials say they found a heater in the Union Bridge apartment, apparently installed to keep pipes from freezing.
