1 dead and 9 missing after chemical tank implosion at Washington mill

Authorities have confirmed that one person died and 9 others were unaccounted for after a chemical tank imploded at a pulp and paper mill in Washington state. Nine others were injured in the spill, some severely. Emergency responders were still working on recovery efforts at Nippon Dynawave Packaging Co. in Longview, but hours after the implosion, some liquid remained in the collapsed tank, complicating efforts to reach victims, the Longview Fire Department said.
