What happened

The death toll from a chemical tank rupture in the US state of Washington climbed to 11 as crews recovered the bodies of all nine missing people, authorities said on Saturday.

Why it matters

Two fatalities had been confirmed after the tank containing “white liquor” – a chemical solution of sodium hydroxide and sodium sulfide used in making paper pulp – imploded at a Nippon Dynawave Packaging facility on Tuesday.

Common ground

The search for the missing carried on through the week as recovery crews worked through debris in indoor areas and flew drones over the perimeter of the site, said the Cowlitz 2 fire and rescue department’s deputy chief, Kurt Stitch.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
