A chemical tank has imploded and ruptured at a pulp and paper mill in the US state of Washington, resulting in one death and nine injuries, while nine others are missing.
A joint written statement with Nippon Dynawave Packaging Company and the Cowlitz County Sheriff's Department said a tank containing "white liquor," a chemical solution of sodium hydroxide and sodium sulfide used in making paper pulp, had ruptured around 7:15am local time on Tuesday.
While the tank was initially believed to hold around 302,830 litres, officials later said it contained closer to 340,687 litres of white liquor.
