SEOUL, South Korea (AP) — An explosion at a chemical plant in South Korea killed six workers on Friday, fire officials said.
The victims were doing welding work when the blast tore down a waste storage facility at a chemical plant run by Hanwha Chemical Co. in the southeastern city of Ulsan, according to the officials.
The exact cause of the explosion wasn’t immediately known. But fire officer Kim Jung-sik said that gas trapped inside the storage might have triggered the blast.
South Korean media reported the six workers were on top of the storage at the time of the explosion, but fire officials said they couldn’t immediately confirm the reports.
