A chemical storage tank implosion at a pulp mill in Longview, Washington, on May 26, 2026, has resulted in at least one death, 10 injuries, and multiple missing persons. The incident highlights critical safety risks in chemical storage and processing operations, relevant for overseas buyers of pulp, paper, and packaging materials who rely on stable supply chains from US-based facilities.
Incident overview
At approximately 7:15 a.m. local time, an 80,000-gallon chemical storage tank, about 60% full, imploded at the Nippon Dynawave Packaging (NDP) mill, a subsidiary of Japan's Nippon Paper Group. The tank contained white liquor, a highly caustic alkaline mixture used in pulp production. The facility employs around 1,000 workers and produces pulp and food packaging materials.
Casualties and response
Local fire departments deployed about 40 firefighters and a regional hazardous materials team, reporting mass casualties. At least 10 people suffered chemical burns and inhalation injuries, ranging from minor to critical. One fatality was confirmed: 52-year-old Gilbert Bernal. Several individuals remain missing, with search and rescue operations ongoing. One firefighter was among the injured.
Environmental and community impact
White liquor leaked into drainage systems following the implosion. The Washington State Department of Ecology has dispatched teams to assess environmental damage. Authorities stated there is no immediate threat to the surrounding community but urged the public to avoid the accident site. The cause of the implosion remains under investigation.
Supply-chain impact
NDP's mill, located on the Columbia River in Longview, is an integrated pulp, paper, and liquid packaging production facility. Longview, a historic industrial city with about 38,000 residents, has a strong forestry and paper industry base. This incident may disrupt supply of pulp and packaging materials, particularly for buyers sourcing from the US Pacific Northwest. Importers and distributors should monitor updates on production downtime and potential shipment delays.
What buyers should watch
Overseas buyers of pulp, paperboard, and food-grade packaging should track official statements from Nippon Dynawave Packaging regarding plant operations and force majeure declarations. The investigation into the tank implosion may lead to stricter safety regulations for chemical storage in the pulp and paper sector, potentially affecting production costs and lead times. Environmental remediation efforts could also extend operational disruptions.
