Washington State Tank Implosion Kills One and Leaves Nine Missing
Authorities said 10 people were injured, including one firefighter, as recovery crews searched for the missing and investigated the cause.
- 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.
