Washington State Tank Implosion Kills One and Leaves Nine Missing
Officials said the tank held about 900,000 gallons of white liquor and recovery crews were still working to account for missing workers.
- On Tuesday, a tank containing white liquor ruptured at Nippon Dynawave Packaging in Longview, Washington, around 7:15 a.m., killing at least one person and leaving nine others unaccounted for while injuring 10 people including a firefighter.
- White liquor is a highly caustic alkaline solution made primarily of sodium hydroxide and sodium sulfide used to break down wood chips in kraft paper production; the substance causes severe chemical burns and can only self-neutralize with water over time.
- Battalion Chief Mike Gorsuch described the aftermath as a 'mass casualty scene' as about 40 firefighters and paramedics responded; nine mill employees and one firefighter were transported to hospitals in Longview and Vancouver.
- PeaceHealth St. John Medical Center received nine patients with one deceased, six in fair condition, and two transferred; rescue crews shifted into recovery operations as the unstable tank posed ongoing hazards for emergency personnel.
- The Nippon facility experienced a major industrial fire in July 2023 and faced OSHA citations for serious safety violations in 2021; authorities initially reported the tank held 80,000 gallons but later revised capacity to 900,000 gallons.
