Chemical tank disaster kills 11
Investigation begins after deadly plant rupture
At least 11 people have been confirmed dead following a chemical tank rupture at a Nippon Dynawave Packaging facility in Longview, Washington, federal and local authorities said, after recovery teams located the bodies of nine workers who had been missing since the initial incident. The accident occurred during the early morning hours when a large storage tank containing “white liquor” — a sodium hydroxide and sodium sulfide solution used in pulp production — imploded and ruptured, sending a powerful release of hazardous material across the site and causing extensive structural damage and multiple injuries. First responders evacuated workers and treated several people at hospitals for chemical burns and other trauma; rescue and recovery operations were hampered for days by unstable structures and toxic conditions inside the facility.
Initial estimates of the tank’s contents were revised upward during the response; officials said the vessel held roughly 900,000 gallons, with tens of thousands of gallons remaining when it failed. Drone and on-scene footage documented a collapsed tank and damaged equipment and vehicles. Environmental testing confirmed that contamination reached the nearby Columbia River, prompting continued water and air monitoring; authorities reported no detected negative health impacts to Longview’s drinking water or ambient air at the time of their last updates. A community vigil was held after the first fatalities were announced, and local leaders expressed condolences while commending emergency crews for their efforts under hazardous conditions.
A multiagency investigation has been launched to determine the causes of the implosion and rupture, with investigators examining equipment operation, chemical-handling procedures, maintenance records and regulatory compliance. The facility remains closed as recovery gives way to forensic and environmental assessments, and cleanup and monitoring operations continue. Labor groups and safety advocates urged a thorough, transparent inquiry and called for strengthened industrial safety oversight to prevent similar tragedies at chemical-handling sites.
