Longview, Washington — A major industrial tragedy has unfolded at a paper packaging facility, where a sudden chemical tank rupture has killed 11 workers after all remaining missing persons were recovered from the site.
According to Beyond Time News, rescue teams confirmed on Saturday that the final nine missing employees were found after days of intensive search and recovery operations at the Nippon Dynawave Packaging plant. The incident has left the community in shock and triggered a full-scale safety investigation.
Sudden Structural Failure Leads to Fatal Incident
The accident took place at the Nippon Dynawave Packaging facility, where a large industrial storage tank unexpectedly ruptured, releasing a massive quantity of chemicals used in paper production.
The tank contained around 900,000 gallons of “white liquor,” a highly corrosive chemical mixture commonly used in pulp processing. While essential for the paper industry, the substance requires strict handling due to its hazardous nature.
Emergency crews were immediately dispatched after the incident, initially confirming two deaths. As operations continued, more victims were located inside severely damaged and debris-filled sections of the plant, raising the final toll to 11.
Difficult and Risky Recovery Operations
Search and recovery efforts continued for several days under extremely dangerous conditions. Large parts of the facility were damaged, with heavy debris limiting access to critical areas where workers were believed to be trapped.
Rescue teams carefully worked through unstable structures while monitoring potential chemical exposure risks. Drones were also deployed to scan restricted zones, helping responders identify safe access points and locate victims.
According to Beyond Time News, coordinated efforts between fire services and specialized response teams ensured that all missing individuals were eventually recovered, marking the end of the operation.
Chemical Spill Raises Environmental Concerns
Following the rupture, officials confirmed that part of the released chemical mixture reached the nearby Columbia River.
Environmental agencies quickly began testing water quality and monitoring surrounding areas. While contamination was confirmed, early assessments indicated no immediate risk to public drinking water supplies or air quality in nearby communities, including Longview.
Authorities continue to monitor the situation closely to detect any delayed environmental effects.
Understanding “White Liquor” in Industrial Use
White liquor is a key chemical used in the paper manufacturing process, where it helps break down wood chips into pulp.
Despite its industrial importance, it is highly alkaline and can pose serious safety risks if released in large quantities. Proper storage and maintenance of equipment are essential to prevent accidents like this.
Background of the Facility
The plant is operated by Nippon Dynawave Packaging, a subsidiary of Japan’s Nippon Paper Industries, a leading global paper manufacturer.
The Longview facility became part of the company’s portfolio in 2016 after its acquisition from Weyerhaeuser in a deal worth approximately $225 million. Since then, it has remained a key production site for pulp and packaging materials.

Investigation and Safety Review Underway
Authorities have launched a detailed investigation to determine the exact cause of the tank failure. Experts are reviewing structural integrity records, maintenance logs, and operational safety procedures.
Regulatory bodies are also examining whether proper industrial standards were followed at the facility.
A final report is expected once the investigation is complete, though officials say it may take considerable time.
Community Reaction and Grief
The incident has deeply affected residents of Longview, where industrial workplaces play a major role in the local economy.
Community members and local leaders have expressed condolences to the families of the victims. Memorial services are expected as the city comes together to mourn the lives lost in the tragedy.
