Chemical tank implosion kills workers at Washington paper mill

A chemical tank imploded at a pulp and paper mill in Longview, Washington, on Tuesday, killing at least one worker and leaving nine others missing.

Emergency crews and investigators remained at the site as officials worked to stabilize the tank and search the plant, making the incident a major industrial safety case with international attention because the mill is tied to a Japanese parent company.

Local authorities

Officials described the site as a mass-casualty scene and focused on rescue, recovery, and securing the remaining chemical in the tank. They said the immediate priority was to prevent further harm before resuming the search for the missing workers.

Company officials

The mill operator said it was working with responders after the tank failed at the facility. Its response centered on containing the hazard and supporting the investigation into what went wrong.

International coverage

Outlets outside the United States highlighted the plant’s ownership link to Japan-based Nippon Paper Group and the industrial risks involved in chemical processing. They treated the event as a workplace disaster with relevance beyond Washington because of the company’s cross-border ties.
