A catastrophic hazardous materials incident at the Nippon Dynawave Packaging facility in Longview, Washington, has caused multiple serious injuries and fatalities after a chemical tank containing “white liquor” ruptured or imploded on Tuesday morning. Emergency officials said the incident occurred at approximately 7:15 a.m. at the pulp and paper mill, where a large tank containing white liquor—a caustic chemical mixture used in the paper-making process—failed.
As of the latest reports, authorities have said the exact number of fatalities remains undetermined, several personnel were missing, and multiple injured people were transported to area hospitals. ABC News reported that nine people at the facility suffered injuries, including chemical burns, and that one firefighter was also injured and treated. PeaceHealth St. John Medical Center reportedly received nine patients, including one person who was deceased, while other burn and exposure patients were transferred or treated at regional facilities, including burn centers in the Portland area.
This is a developing story. The facts may change as recovery efforts continue, officials notify families, and investigators determine why the tank failed. What is already clear is that this tragedy raises urgent questions about chemical storage, tank integrity, process safety, emergency response, and whether preventable safety failures contributed to the deaths and injuries at the Nippon Dynawave facility.
At Pritzker Hageman, our national explosion lawyers and burn injury lawyers represent workers, contractors, firefighters, visitors, and families after industrial explosions, fires, chemical releases, and catastrophic burn injuries. Our legal team investigates the root cause of explosions and chemical incidents to determine whether a company, contractor, manufacturer, maintenance provider, engineering firm, or other third party failed to prevent the disaster.
What Happened at the Nippon Dynawave Facility in Longview?
The Nippon Dynawave Packaging facility is located at 3401 Industrial Way in Longview, Washington, near the Columbia River. The Washington Department of Ecology describes the site as a kraft pulp and paper mill and liquid packaging plant. Ecology states that it regulates the facility’s air, water, and hazardous waste activities, and that the pulp and paper mill makes approximately 280,000 tons of bleached liquid packaging paperboard and wetlap and slush pulp each year.
According to ABC News and other reports, a tank containing white liquor ruptured or imploded at about 7:15 a.m. Authorities initially described the event as a chemical explosion, then as an implosion, and later as a rupture. The tank was reportedly an 80,000-gallon tank and was about 60% full at the time of the incident. White liquor was described by officials as a mixture of sodium hydroxide, sodium sulfide, and disodium carbonate used in the paper-making process.
Emergency officials reportedly said the incident was stable but in a recovery phase later in the day. Residents were urged to avoid the area while emergency responders, hazardous materials teams, facility personnel, and partner agencies continued operations. Authorities also said there was no immediate threat to the public.
Those public assurances are important for the surrounding community, but they do not lessen the severity of what happened inside the facility. Workers and first responders exposed to white liquor may suffer chemical burns, inhalation injuries, eye injuries, respiratory damage, traumatic injuries from the tank failure, and psychological trauma. Families of those killed or missing are now facing the devastating uncertainty and grief that follows a catastrophic industrial accident.
What Is “White Liquor” and Why Is It Dangerous?
White liquor is a strongly alkaline chemical solution used in kraft pulping. In the pulp and paper industry, it helps break down wood chips by separating lignin and hemicellulose from cellulose fibers. The solution commonly contains sodium hydroxide, often known as caustic soda, and sodium sulfide. Officials also identified disodium carbonate as part of the chemical mixture involved in the Nippon Dynawave incident.
The danger is not just that white liquor is used in an industrial process. The danger is the combination of caustic chemistry, large storage volumes, industrial piping and tanks, possible pressure or vacuum conditions, heat, confined or semi-confined work areas, and the number of workers who may be nearby during normal operations. A sudden tank rupture can release a large volume of corrosive liquid and vapors, injure people with chemical exposure, create inhalation hazards, damage surrounding equipment, and complicate rescue efforts.
Chemical burns are different from thermal burns caused by flame. A caustic chemical can continue damaging skin, eyes, and tissue until it is removed or neutralized through proper emergency decontamination and medical care. Victims may need specialized treatment at burn centers, repeated surgeries, skin grafting, respiratory support, eye care, infection treatment, and long-term rehabilitation.

Key Questions The Investigation Will Establish After the Nippon Dynawave Chemical Tank Failure
The cause of the tank failure has not been determined. In any industrial chemical explosion, implosion, rupture, or release, investigators should move quickly to preserve evidence before it is altered, repaired, removed, or destroyed. The most important evidence often includes the failed tank itself, inspection records, maintenance records, process data, alarms, operator logs, contractor work records, surveillance video, employee statements, safety audits, and communications before and after the incident.
Investigators will need to determine whether the tank was properly designed for the chemicals and operating conditions involved. They will examine whether the tank had a known history of corrosion, thinning, cracking, leaks, over-pressurization, vacuum conditions, foundation problems, faulty valves, blocked vents, instrumentation failures, or prior repairs. They will also look at whether the company followed applicable safety standards, manufacturer instructions, engineering recommendations, and internal safety procedures.
Industrial tanks do not usually fail without warning. Sometimes a catastrophic rupture is preceded by years of overlooked corrosion, inadequate inspection, poor mechanical integrity programs, deferred maintenance, improper modifications, missing relief protection, operator error caused by inadequate training, or management decisions that prioritize production over safety. No conclusion should be reached until the evidence is reviewed, but these are exactly the issues that an independent investigation should address.
Pritzker Hageman’s fire and explosion injury lawyers often work with origin-and-cause experts, engineers, chemical safety professionals, metallurgists, fire investigators, human factors experts, and medical experts to determine what happened and who may be legally responsible. In explosion and burn cases, it is critical to begin the investigation as soon as possible. Our article on why burn injury lawyers investigate gas explosions nationwide explains why independent investigations matter after catastrophic burns and wrongful death.
OSHA, Process Safety, and Chemical Tank Failures
The Occupational Safety and Health Administration’s process safety management framework is designed to help prevent or minimize catastrophic releases of highly hazardous chemicals. OSHA identifies process safety management as addressing hazards that can lead to toxic, fire, and explosion consequences. OSHA also has standards and guidance related to pulp, paper, and paperboard mills, hazardous materials, confined spaces, employee training, emergency response, and workplace safety.
Whether OSHA’s process safety management standard applies to a particular process depends on the chemicals, quantities, and regulatory criteria involved. Regardless of the ultimate regulatory classification, industrial facilities handling large volumes of caustic chemicals should have robust safety systems. These include hazard analysis, written operating procedures, employee training, mechanical integrity programs, inspection and testing, management of change procedures, emergency planning, incident investigation, contractor safety controls, and prompt correction of known hazards.
The U.S. Chemical Safety and Hazard Investigation Board, commonly called the CSB, investigates the root causes of major chemical incidents and has repeatedly emphasized the importance of mechanical integrity, hazard recognition, process safety culture, and learning from near misses. Industrial companies should not wait for a fatal incident before taking tank integrity, chemical hazards, and emergency preparedness seriously.
Potential Injuries from the Nippon Dynawave Explosion and Chemical Release
The injuries reported after the Nippon Dynawave incident include chemical burns, traumatic injuries, and exposure-related injuries. In an incident like this, victims may suffer severe skin burns, eye injuries, inhalation injuries, respiratory failure, crush injuries, fractures, traumatic brain injuries, hearing damage, nerve damage, infection, scarring, disfigurement, amputation, and post-traumatic stress disorder.
Burn injuries are among the most painful and life-altering injuries a person can suffer. Survivors often face weeks or months of hospitalization, multiple surgeries, painful dressing changes, skin grafts, reconstructive procedures, physical therapy, occupational therapy, pressure garments, treatment for contractures, and long-term psychological care. Families may also face lost income, travel costs, temporary housing near a burn center, home modifications, and the need for long-term caregiving.
Pritzker Hageman represents people with explosion burn injuries and helps families understand whether they may have a burn injury lawsuit. When a loved one dies, families may also need to consider whether they have an explosion wrongful death lawsuit.
Can Injured Workers Sue After the Nippon Dynawave Explosion?
Many people injured in industrial disasters are workers. After a workplace injury in Washington, workers’ compensation may provide certain benefits regardless of fault. However, workers’ compensation may not fully compensate a worker or family for all losses caused by a catastrophic chemical burn, explosion injury, or wrongful death.
In many workplace disaster cases, an injured worker may also have a third-party claim if someone other than the worker’s employer or co-worker caused or contributed to the incident. Washington L&I explains that if someone other than the employer or co-worker caused a workplace injury or illness, the worker may be able to take legal action against that third party. In an industrial chemical tank failure, potential third parties may include outside maintenance contractors, inspection companies, engineering firms, equipment manufacturers, valve manufacturers, instrumentation suppliers, construction contractors, chemical suppliers, or other companies responsible for unsafe work at the site.
The facts matter. A third-party claim depends on evidence showing that another company or entity had a legal duty and failed to meet that duty. That is why it is important for injured workers and families to speak with lawyers who understand industrial explosions, chemical burns, and workplace third-party claims.
Pritzker Hageman’s explosion injury lawyers investigate whether victims have claims beyond workers’ compensation. In some cases, a lawsuit can seek compensation for pain and suffering, past and future medical expenses, lost income, loss of earning capacity, disability, disfigurement, emotional distress, loss of companionship, and other damages not fully addressed by workers’ compensation benefits.
Who Could Be Responsible for a Chemical Tank Explosion or Rupture?
It is too early to say who may be legally responsible for the Nippon Dynawave incident. Any responsible-party analysis must wait for a careful review of physical evidence, maintenance records, inspection history, engineering data, witness accounts, and regulatory findings. However, in chemical tank rupture cases, investigators often examine whether one or more parties failed to prevent a known or foreseeable hazard.
Potentially responsible parties in industrial explosion and chemical burn cases can include the facility operator, a parent company, a tank manufacturer, a tank installer, an engineering firm, an inspection company, a maintenance contractor, a valve or instrumentation manufacturer, a chemical process consultant, or another contractor working at the facility. In some cases, liability may involve defective design, defective equipment, negligent maintenance, inadequate inspections, improper repairs, failure to warn, poor training, unsafe procedures, or failure to follow industry standards.
An independent legal investigation may also uncover evidence that differs from early public statements. Initial explanations after an explosion are often incomplete. Evidence can reveal a preventable chain of events involving ignored warnings, inadequate tank inspections, missing safeguards, poor communication between contractors and facility personnel, or management decisions that allowed unsafe conditions to continue.
Our explosion lawyers understand that catastrophic industrial incidents are rarely “just accidents.” They are often the result of preventable failures that only become clear after a thorough investigation.
Why Families Should Act Quickly After a Chemical Explosion
After a catastrophic explosion or chemical release, companies and insurers often begin investigating immediately. They may send experts to the site, secure documents, interview witnesses, and develop their defense while injured people are still hospitalized and families are grieving. Victims and families deserve their own investigation.
Acting quickly can help preserve key evidence, including the failed tank, damaged valves and piping, inspection records, process data, safety meeting notes, contractor records, photographs, video, and witness testimony. Delay can make a case harder to prove because physical evidence can be altered, memories can fade, and critical documents can become more difficult to obtain.
Families should also be careful about giving recorded statements, signing documents, accepting quick payments, or communicating with insurance representatives before speaking with an experienced lawyer. After a severe burn injury or wrongful death, the full value of a case cannot be understood until the medical prognosis, long-term care needs, lost income, and liability evidence are carefully evaluated.
