Longview, Washington – The industrial community of Longview is reeling today, May 27, 2026, from a catastrophic chemical tank implosion at the Nippon Dynawave Packaging Co. paper mill. The devastating incident, which occurred on Tuesday morning, May 26th, has tragically claimed the life of at least one worker, left nine others missing, and injured several, including emergency responders. The ongoing crisis has cast a somber shadow over the region, highlighting critical concerns about industrial safety, environmental protection, and the profound human cost of such disasters. [2]
As recovery efforts continue amidst hazardous conditions, the focus remains on accounting for the missing and understanding the full scope of this tragic event. The incident serves as a stark reminder of the inherent risks in heavy industry and the paramount importance of stringent safety protocols. [2]
The implosion took place at approximately 7:15 AM local time on Tuesday, May 26, 2026, at the Nippon Dynawave Packaging Co. facility in Longview, Washington. [8] The facility, a significant employer in the area with around 1,000 workers, specializes in producing materials for tissues, printing paper, cups, plates, cartons, and other goods. [10]
Initial reports indicated the rupture of a chemical tank, which authorities later identified as containing a highly corrosive substance known as "white liquor." This chemical brew, primarily composed of sodium hydroxide and sodium sulfide, is crucial in the kraft paper manufacturing process, used to break down wood pulp. [3]
Early estimates suggested the tank had a capacity of 80,000 gallons. However, officials later revised this figure dramatically, stating that the tank was holding approximately 900,000 gallons (3.4 million liters) of the corrosive liquid – over ten times the initial assessment. [4] This substantial volume underscores the potential for widespread damage and hazard. Roughly 90,000 gallons of the material are believed to still remain within the damaged tank, complicating recovery efforts. [4]
The human toll of this disaster is heartbreaking. Authorities have confirmed one fatality, and a desperate search is underway for nine individuals who remain unaccounted for. [2] The situation has officially shifted from a rescue operation to a recovery effort, with officials expressing little hope of finding the missing alive due to the hazardous conditions. [5]
In addition to the confirmed death and missing persons, nine others sustained injuries in the incident. These include eight employees of the mill and one responding firefighter. [7] The injuries reported range from minor to critical, with some victims suffering severe burns and inhalation injuries due to exposure to the caustic chemicals. [2] Four of the most severely injured have been transferred to the Legacy Oregon Burn Center in Portland, Oregon, for specialized treatment.
Here’s a snapshot of the immediate impact:
| Incident Detail | Status/Count |
|---|---|
| Confirmed Fatalities | 1 |
| Missing Personnel | 9 |
| Injured Personnel | 9 (8 employees, 1 firefighter) |
| Severity of Injuries | Minor to Critical (burns, inhalation injuries) |
| Tank Capacity (Revised) | ~900,000 gallons of White Liquor |
| Liquid Remaining | ~90,000 gallons |
| Incident Date | Tuesday, May 26, 2026 (reports updated May 27, 2026) |
| Location | Nippon Dynawave Packaging Co., Longview, WA |
Emergency services, led by the Longview Fire Department and Cowlitz Fire and Rescue, immediately mobilized, with approximately 40 firefighters and paramedics, alongside a regional hazmat team, on the scene. However, the recovery operation has been severely hampered by the unstable condition of the collapsed tank and the lingering presence of the corrosive white liquor. [2]
Cowlitz Fire and Rescue Chief Scott Goldstein has described the scene as a "mass casualty scene" and emphasized the dangerous environment responders are navigating. Efforts are focused on structurally reinforcing and stabilizing the site before further recovery operations can safely proceed, with work expected to resume Wednesday morning during daylight hours due to the risk of further leaks or collapse. [2]
The implosion also triggered an environmental response, as the white liquor spilled into a drainage ditch. The Washington State Department of Ecology deployed a team to assess the impact of the spill. [3] State Ecology Department spokesperson Brittny Goodsell confirmed that the diking system's pumps, which discharge into the Columbia River, have been shut off to prevent further contamination. Unlike oil, white liquor cannot be simply contained and collected; it must "self-neutralize" over time with water. This presents a unique challenge for environmental mitigation and monitoring.
While officials have stated there is no immediate threat to the public, the long-term environmental consequences of such a substantial chemical release will require careful monitoring and assessment.
The Nippon Dynawave Packaging Co. facility is not just an industrial plant; it's an integral part of the Longview community's identity and economy. Established in 1953, the mill is a major employer, providing livelihoods for hundreds of families. U.S. Senator Patty Murray of Washington acknowledged the deep community ties, stating, “The people who are responders here have friends and relatives that work on site. It is something that is impactful…”
The incident’s impact extends far beyond the immediate casualties, affecting the families of the missing and injured, and sending shockwaves through the entire Longview workforce. A family assistance center has been established at the Association of Western Pulp and Paper Workers union hall to support those impacted.
The use of "white liquor" is standard in the chemical pulping process to separate cellulose fibers from wood. While essential for producing various paper products, its highly corrosive nature necessitates stringent handling and storage protocols. Sodium hydroxide (caustic soda) and sodium sulfide are potent chemicals that can cause severe burns and respiratory issues upon exposure, as tragically evidenced by the injuries sustained in this incident. [2]
Industrial facilities like paper mills operate with inherent risks due to the scale of operations, the machinery involved, and the chemicals used. Therefore, robust safety management systems, regular maintenance, employee training, and adherence to regulatory standards are crucial to prevent catastrophic failures. The cause of the implosion at Nippon Dynawave is currently under investigation, and authorities have indicated it is too early to determine. [2] However, the findings of this investigation will be vital in understanding what went wrong and how future incidents can be averted.
This incident at the Longview paper mill, while specific in its details, unfortunately, resonates with a broader national and international conversation around industrial safety. Recent months have seen a spate of industrial accidents, some resulting in fatalities and widespread evacuations. [3] For example, a damaged chemical tank at an aerospace plant in Southern California recently prompted the evacuation of thousands, and a chemical leak in West Virginia in April killed two people. [7]
These events underscore the continuous need for vigilant regulatory oversight and industry commitment to safety. Agencies like the Occupational Safety and Health Administration (OSHA) play a critical role in setting and enforcing workplace safety standards. It's noteworthy that the Washington Department of Labor and Industries had inspected the Nippon Dynawave plant three times over the past five years, citing it for violations, though these were reportedly unrelated to storage safety or chemical processing. This fact will likely be scrutinized as part of the ongoing investigation.
The chemical industry and facilities that utilize hazardous materials must constantly evaluate and update their risk assessments, emergency response plans, and infrastructure integrity. Preventing such tragedies requires a multi-faceted approach involving engineering controls, administrative procedures, and a strong safety culture from the top down.
The immediate priority remains the recovery of the missing and providing support to the affected families. Washington Governor Bob Ferguson has expressed his deep sadness and confirmed that state ecology workers are on site. [13] U.S. Senator Patty Murray also conveyed her condolences, stating, "My heart is with everyone who lost a loved one today — as well as the injured workers."
Long-term, a thorough and transparent investigation into the implosion's cause is imperative. This will involve various agencies collaborating to determine if structural failures, operational errors, maintenance issues, or other factors contributed to the disaster. The findings will not only be crucial for accountability but also for implementing corrective measures to prevent similar incidents in the future. The community of Longview, known for its resilience and strong industrial heritage, will undoubtedly rally to support those impacted.
The chemical tank implosion at the Nippon Dynawave Packaging Co. mill in Longview is a profound tragedy that has left a community in mourning and a nation reflecting on industrial safety. The loss of life, the search for the missing, and the injuries sustained serve as a painful reminder of the critical importance of preventing such disasters. As recovery efforts continue and investigations unfold, the lessons learned from Longview must catalyze renewed commitments to worker safety, environmental protection, and the continuous improvement of industrial practices. Only through sustained vigilance and a shared dedication to safety can we hope to avert future tragedies and ensure that our industrial progress does not come at an unbearable human cost.
