One dead, two injured in gas leak at Samsung chip plant

One worker was killed and two injured when carbon dioxide leaked at a Samsung Electronics chip plant on Tuesday, the South Korean company said. The three were found unconscious in the basement of the semiconductor factory in Suwon just south of Seoul, the firm said in a statement.
A man aged 24 was pronounced dead in hospital hours later and two others, aged 26 and 54, remain unconscious, Samsung said. All were employees of one of Samsung's suppliers and were inspecting the factory's gas-related facilities, it added. "It is believed that the cause of death is suffocation due to a carbon dioxide leak," Samsung said, adding it was investigating.
