One killed and nine missing after chemical tank implodes in Washington

At least one person has been killed and nine others are unaccounted for after a chemical tank imploded in the US.

The incident happened at a pulp and paper mill in Washington state at 7.15am local time on Tuesday (3.15pm UK time).

At least nine other people, including a responding firefighter, were injured in the spill at the Nippon Dynawave Packaging facility in Longview.

Some of those injured had suffered burns or inhalation injuries, authorities said, with the severity of the injuries ranging from minor to critical.

Officials have said there is no immediate threat to the public.

In a statement, the Longview Fire Department said the tank "remains unstable", which was creating "hazardous conditions for emergency personnel".

It added: "Responders are continuing efforts to structurally reinforce and stabilise the site before additional recovery operations can safely proceed."

Patty Murray, a US senator from Washington, called the incident an "absolute tragedy" and said that "my heart is with everyone who lost a loved one today".

Meanwhile, Washington governor Bob Ferguson said that state ecology workers had been deployed to the scene.

He said: "I'm deeply saddened to hear that there have been fatalities. My thoughts are with the workers and their families, and with the first responders."

It comes three days after 40,000 people were ordered to evacuate amid the threat of a chemical tank explosion at an aerospace plant in southern California.

The damaged storage tank at the facility in Garden Grove had been venting methyl methacrylate - a hazardous and highly flammable chemical used to make plastic parts - into the air after it overheated, officials said.
