Two people have been confirmed dead and nine others are unaccounted for following a significant incident at the Nippon Dynawave paper mill in Longview, Washington, on May 26. The tragedy unfolded when a 900,000-gallon tank containing a highly hazardous chemical known as white liquor imploded at approximately 7:15 a.m. on Tuesday.
According to officials, one individual died at the scene while another succumbed to injuries at a hospital. Washington Governor Bob Ferguson described the event as “the deadliest industrial tragedy in modern Washington state history” during a press conference held on Wednesday.
The Incident and Immediate Responses
In addition to the fatalities, eight individuals, including a firefighter, sustained injuries and were transported to local hospitals for treatment. Some of the injured are currently receiving care at the Oregon Burn Center.
Recovery operations commenced on Wednesday to locate the nine individuals presumed dead. Officials indicated that as remains are recovered, they will undergo decontamination prior to being sent to the Cowlitz County Coroner’s Office for identification and family notification.
Investigation and Safety Measures
Initial recovery efforts faced delays due to safety concerns regarding the structural integrity of the damaged tank, which was believed to still contain about 90,000 gallons of the hazardous chemical. However, a subsequent inspection determined that only approximately 25,000 gallons remained in the tank, which was deemed stable enough for responders to devise a recovery plan.
Authorities are actively investigating the cause of the tank’s implosion and assessing the risk of a similar incident occurring in the future. The U.S. Chemical Safety and Hazard Investigation Board (CSB) is set to commence an investigation into this catastrophic event.
Community Impact and Ongoing Concerns
Officials have indicated that there is no immediate threat to the surrounding community. Residents are advised to avoid the area and stay clear of streets between Washington Way and Prudential Boulevard. Currently, there are no reported negative impacts on air quality or the drinking water system in Longview.
While recovery efforts continue, community members are urged to avoid ditches and dikes within the city as water testing is being conducted to ensure safety. Authorities remain vigilant in monitoring the situation and providing updates to the public.
