Why It Matters
A catastrophic industrial accident at a Pacific Northwest paper mill has left at least one worker dead, nine others unaccounted for, and multiple people hospitalized — including a first responder — raising urgent questions about industrial safety at one of the region’s most storied manufacturing facilities.
The incident unfolded in Longview, Washington, a city of roughly 38,000 residents whose economy and identity have been closely tied to the timber and paper industries for more than a century. The ripple effects are being felt across the wider Pacific Northwest region, including communities in neighboring Idaho that share economic and industrial ties with Southwest Washington.
What Happened
A large storage tank holding a hazardous chemical solution imploded Tuesday at the Nippon Dynawave Packaging Co. facility in Longview, triggering what authorities described as a mass casualty incident. Emergency responders confirmed one fatality and said nine employees remained missing as of Tuesday evening.
Nine additional workers sustained injuries, with conditions ranging from minor to critical. Some victims suffered burns or respiratory injuries from inhalation exposure. A responding firefighter was also among the injured.
The tank — holding roughly 900,000 gallons of a caustic industrial solution called “white liquor,” composed primarily of sodium hydroxide and sodium sulfide — ruptured and spilled into a drainage ditch on the property. White liquor is a standard chemical compound used in kraft paper production, the durable material found in packaging and shopping bags.
Recovery operations were significantly hampered throughout Tuesday because liquid remained inside the collapsed tank structure. The Longview Fire Department stated that the tank was still structurally unstable, creating dangerous conditions for personnel attempting to reach potential victims.
“The tank remains unstable, creating hazardous conditions for emergency personnel,” the department said in a written statement, adding that crews were working to stabilize the site before expanding recovery operations.
By the Numbers
- 1 confirmed fatality as of Tuesday evening
- 9 workers unaccounted for
- 9 additional workers injured, some critically
- 900,000 gallons of corrosive white liquor contained in the imploded tank
- ~40 firefighters and paramedics deployed to the scene
- ~1,000 employees work at the Nippon Dynawave facility
About the Facility
The Nippon Dynawave plant sits along the Columbia River in an industrial corridor shared by timber, paper, and chemical operations. The facility has been in operation since 1953 and produces materials used in tissues, printing paper, cups, plates, and cartons.
Cowlitz Fire and Rescue Chief Scott Goldstein acknowledged the personal weight the incident carries for local first responders. “The people who are responders here have friends and relatives that work on site,” he said, noting that support networks were being activated for both workers and emergency personnel.
A Washington state Department of Ecology spokesperson said the agency deployed a team to assess environmental impacts following the chemical spill into the drainage ditch.
Zoom Out
The Longview explosion is not an isolated event in a broader pattern of industrial chemical incidents. A report released in late 2023 by a network of environmental advocacy organizations found that more than 40 people died in the United States as a result of hazardous chemical incidents between early 2021 and mid-October 2023.
Separately, thousands of Southern California residents remained under evacuation orders Tuesday following a damaged chemical tank at an aerospace facility — underscoring the simultaneous industrial safety challenges facing communities across the country.
Washington state has faced other pressing challenges in recent months. Only a fraction of the state’s flood aid funding has reached victims from recent weather disasters, raising broader concerns about the government’s ability to respond effectively to overlapping emergencies.
What’s Next
Authorities said the immediate priority remains stabilizing the collapsed tank structure to allow safe recovery operations to continue. An investigation into the cause of the implosion is expected to be launched, though officials said Tuesday it was too early to determine what triggered the failure.
State and federal regulators are likely to conduct a formal review of safety conditions at the Longview facility. U.S. Sen. Patty Murray called the incident “an absolute tragedy” and expressed condolences to the families of those affected.
