One dead, six hospitalized while cleaning wastewater tank at Hyundai Steel plant in Incheon

INCHEON, One worker died and six others were hospitalized after they collapsed while cleaning a wastewater treatment tank at a Hyundai Steel factory in Incheon, police said Tuesday. The workers were removing hydrofluoric and nitric acid sludge from the tank without wearing gas masks at the plant in Incheon, 27 kilometers west of Seoul, when they suddenly collapsed at 11:02 a.m., according to firefighting and police officials. One of them, aged 34, was taken to a hospital in a state of cardiac arrest but died later. The six others were also receiving treatment for breathing difficulties and decreased consciousness, officials said. Police suspect the workers suffered suffocation from unidentified gases in the tank. "We're considering whether to ask the National Forensic Service to conduct an autopsy to figure out the cause of the death," a police official said. "We're trying to determine the cause of suffocation by analyzing the substances in the tank." The workers belong to an outside cleaning firm. So urce: Yonhap News Agency
