Deadly hydrogen cyanide gas killed four workers and injured at least 11 at a metal plating company in Auburn, Ind., when an employee used the wrong chemical to clean a processing tank, officials said. A spokeswoman for the state Department of Environmental Management said that a tank of zinc cyanide was being cleaned when a worker, who was not identified, used muriatic acid by mistake. The combination of the two produces hydrogen cyanide, a powerful poisonous vapor. The dead were all employees of Bastian Plating Inc.
