One dead, three in critical condition in power plant gas leak

A fatal gas leak at a local power plant left one dead and three others in critical condition on Tuesday, local authorities said.

Police here in Dangjin, South Chungcheong Province, about 120 kilometers south of Seoul, said the leak at Hyundai Greenpower's plant at around 7 p.m. Tuesday killed a worker surnamed Yang. Eight others were transferred to Dangjin Hospital, with three of them said to be in critical condition.

Police believe that one worker was doing maintenance work on the plant's boiler when he was poisoned with leaked gas, and his co-workers that came to his aid also inhaled toxic material.

Police added that the gas didn't travel out of the power plant. (Yonhap News)
