Longview Nippon Dynawave Implosion Attorney | Oslund Udo Little

On May 26, 2026, a catastrophic chemical tank rupture at Nippon Dynawave Packaging Co. killed 11 workers in what Washington Governor Bob Ferguson called the “deadliest industrial tragedy in the state’s modern history.” Eight more were critically injured.

If you or a loved one was injured in the Nippon Dynawave implosion, or if you lost someone in this tragedy, Oslund Udo Little is here for you. We are based in the Pacific Northwest. We know Longview. We know the paper mill industry. And we have spent nearly 30 years fighting corporations that put profits over people’s safety.

What Happened at Nippon Dynawave on May 26, 2026

At approximately 7:15 a.m. on Tuesday, May 26, 2026, a massive storage tank containing “white liquor” – a highly corrosive chemical mixture used in the kraft pulp and papermaking process – ruptured and imploded at the Nippon Dynawave Packaging facility located at 3401 Industrial Way in Longview, Washington. The tank held approximately 80,000 gallons of the chemical (some reports suggest the capacity was nearly 900,000 gallons), and it was about 60% full at the time of the failure.

The implosion released tens of thousands of gallons of dangerous chemicals across the facility with no warning. Workers in the area suffered severe chemical burns, inhalation injuries, and in some cases were submerged in the released chemical. The sudden, catastrophic failure prevented workers from evacuating or protecting themselves. A water main rupture at the facility compounded the disaster, spreading the caustic chemical mixture across a wider area.

Eleven workers were killed. Eight more were severely injured, including at least one firefighter who responded to the emergency. Five days passed before recovery crews located and removed all nine missing victims from inside the facility. The exact cause of the tank’s failure remains under investigation.

The Safety Record That Preceded the Disaster

Like many large industrial sites, Nippon’s Longview facility has had prior incidents and safety citations. Public records and regulatory databases reveal a pattern of violations and unresolved safety concerns at the Longview facility in the years leading up to May 26:

Washington State Regulatory Violations
Between 2019 and 2025, the Washington Department of Labor & Industries cited Nippon Dynawave four times for safety violations, with penalties totaling only $3,400 — a fraction of what could have been imposed on a facility employing over 1,000 workers.
Federal OSHA Violations
Federal OSHA cited the facility in 2021 for a serious violation, with a penalty of only $2,700.
Environmental Violations
The Washington Department of Ecology cited Nippon Dynawave for violations including exceeding wastewater discharge limits and air emissions thresholds. Federal records showed the facility was out of compliance with Clean Water Act requirements every quarter for at least three years prior to the May 2026 implosion.
Major Industrial Fire
In July 2023, the facility experienced a large industrial fire that burned for multiple days, sending thick smoke across southwest Washington and into Portland, prompting air quality advisories across the region.
Open Investigations at the Time of the Disaster
At the moment the tank failed on May 26, 2026, two separate safety investigations were already underway at the facility. One, opened in March 2026, stemmed from an anonymous complaint about a valve on a tank holding aqua ammonia — another highly corrosive chemical. The second, opened May 6, 2026, concerned a sinkhole caused by a failed drain system. Neither investigation had been completed.

Who May Have a Legal Claim in the Nippon Dynawave Implosion

If you or a family member fall into any of the categories below, you may have a legal claim beyond what workers’ compensation provides:

Nippon Dynawave Employees Injured in the implosion
If you worked at Nippon Dynawave and suffered chemical burns, inhalation injuries, eye injuries, or other physical harm in the May 26 incident, you have rights.
Contractors, Subcontractors, and Visitors
If you were working at the facility for a contractor, maintenance company, or other third party, or if you were present at the facility for any work-related reason and were injured, you may have claims.
Firefighters and First Responders Injured at the Scene
Emergency personnel who responded to the disaster and suffered injuries may have claims beyond standard workers' compensation.
Family Members of Workers Killed in the implosion
If you lost a spouse, parent, child, or other family member in this disaster, Washington law allows you to pursue a wrongful death claim. These claims seek compensation for funeral and burial expenses, loss of your loved one's financial support, loss of companionship, and the grief and emotional suffering caused by their death.
Workers Exposed to Chemicals or Vapors in Nearby Areas
Even if you were not directly at the tank rupture site, if you were working in an area of the facility and were exposed to released chemicals or vapors, you may have a claim.
Family Members Exposed Through a Worker's Contaminated Clothing
In some industrial chemical exposure cases, family members are exposed when a worker brings contaminated clothing or chemicals home. If you suffered injury or illness from such secondary exposure, you may have a claim.

Legal Options: Beyond Workers' Compensation

In Washington state, injured workers typically receive workers’ compensation benefits for workplace injuries. Workers’ compensation covers medical expenses and a portion of lost wages. But workers’ compensation has strict limits – it does not cover pain and suffering, full lost earnings, wrongful death, or punitive damages.

What workers’ compensation also does not do: hold negligent parties accountable for their conduct. When a workplace injury is caused by the negligence of someone other than the employer, the injured worker or bereaved family can often pursue a separate civil lawsuit.

A civil claim against these parties can result in greater compensation than workers’ compensation alone, because it allows recovery for pain and suffering, permanent disfigurement, loss of future earning capacity, and in cases of gross negligence or willful disregard of safety, punitive damages.

What Compensation Can Be Recovered in a Nippon Dynawave Implosion Claim?

If you pursue a civil claim related to the Nippon Dynawave implosion, potential damages include:

Economic Damages:

Medical expenses – emergency treatment, hospital stays, surgery, skin grafting, burn treatment, rehabilitation, and long-term medical care and monitoring

Lost wages from the date of injury through recovery (if you can return to work)

Reduced future earning capacity if injuries prevent you from returning to your previous job

Cost of future medical care, prosthetics, home modifications, or assistive devices

Non-Economic Damages:

Pain and suffering from chemical burns, inhalation injuries, and medical treatment

Permanent scarring or disfigurement from chemical burns

Loss of enjoyment of life caused by permanent disability or limitations

Psychological trauma, PTSD, anxiety, and depression

Loss of companionship and consortium (in cases where injuries affect family relationships)

Wrongful Death Damages:

Funeral and burial expenses

Loss of the deceased’s financial support to the family

Loss of the deceased’s companionship, guidance, and society

Emotional suffering and grief caused by the death

The exact damages recoverable in your case will depend on the specific facts of your injury, the liability evidence, and the defendants involved. This is precisely why early consultation with an experienced attorney is so important – the attorney can evaluate your case and explain what compensation you may be entitled to pursue.

Why Acting Now Is Critical: Evidence Preservation and Statute of Limitations

The Window for Evidence Preservation is Open Now

In the days and weeks following the Nippon Dynawave implosion, critical evidence exists at the scene and in company records:

The ruptured tank itself and its remains

Inspection records, maintenance logs, and repair history

Communications between company employees about safety concerns

Training records and operating procedures

Surveillance video

First responder reports and scene documentation

Employee statements given while memories are fresh

Although government agencies are actively investigating the cause of the Nippon tragedy, a civil attorney has additional tools to ensure evidence is preserved. For example, a formal evidence preservation notice can be issued to Nippon Dynawave, its insurers, contractors, equipment manufacturers, and others – requiring them by law to preserve all evidence related to the incident. Without this notice, critical evidence may be lost through oversight or record retention policies.

Statute of Limitations in Washington

In Washington state, the general statute of limitations for personal injury claims (RCW 4.16.080) is three years from the date of injury, and three years from the date of death for wrongful death claims. These deadlines are not flexible, and there are limited exceptions. For the Nippon Dynawave implosion (May 26, 2026), this means known personal injury claims must be filed by May 26, 2029, and wrongful death claims have a similar deadline.

While three years may sound like a long time, it passes quickly, especially when you are dealing with medical recovery, grief, or ongoing treatment. The earlier you consult with an attorney, the better your case will be prepared and the more time we have to investigate, preserve evidence, and build a strong claim.

Frequently Asked Questions About the Nippon Dynawave Implosion and Your Legal Rights

I worked at Nippon Dynawave, but I was not at the tank rupture site. Do I still have a claim?

Yes, potentially. If you were working in an area of the facility and were exposed to released chemicals, vapors, or contamination from the implosion, or if you experienced psychological trauma from witnessing the disaster or learning of colleagues’ deaths, you may have a claim. Contact us to discuss your specific situation.

My family member died in the implosion. What are my legal options?

We are deeply sorry for your loss. Surviving family members – including spouses, children, and dependent parents – can pursue a wrongful death claim. This claim seeks compensation for funeral expenses, loss of the deceased’s financial support, loss of companionship, and your grief and emotional suffering. This is exactly the kind of case Oslund Udo Little handles, and we have successfully represented families in similar circumstances. Contact us for a confidential consultation.

I'm receiving workers' compensation. Can I still pursue a separate lawsuit?

Yes. Workers’ compensation and a civil lawsuit are separate. You can receive workers’ compensation benefits and also pursue a claim against negligent third parties – equipment manufacturers, contractors, or others whose actions contributed to the explosion. In fact, you should consult with an attorney about your full legal options, because a third-party claim may result in far greater compensation than workers’ compensation alone.

What if I signed something from Nippon Dynawave or the insurance company?

Do not panic. Depending on what you signed and the circumstances, we may be able to challenge an unfavorable release or settlement offer. Contact us immediately with a copy of what you signed. Do not sign anything else without consulting an attorney.

How long do I have to file a claim?

In Washington, the general statute of limitations is three years from the date of injury (May 26, 2026, means you would have until May 26, 2029) or three years from the date of death for wrongful death claims. However, time limits can vary based on specific circumstances, and there are exceptions in some cases. The safest approach is to contact an attorney as soon as possible. Do not wait until the deadline is near.

How much will it cost to hire Oslund Udo Little?

Nothing upfront. We handle cases like this on a contingency fee basis. You pay nothing at all unless we recover compensation for you – whether through settlement or trial verdict. Your initial consultation is free and completely confidential.

I'm worried about my medical bills while my case is pending. What should I do?

Gather all medical bills and records. In some cases, we can work with medical providers to defer or negotiate bills while a case is pending. Your attorney will discuss options with you.

What if the cause of the implosion is not determined by the time my claim is ready?

We do not need the official government investigation to be complete to file a claim. In fact, we conduct our own investigation – including hiring independent engineers and experts to analyze the tank, review records, and determine what caused the failure. Our investigation often uncovers facts that official inquiries do not. We can file a claim and continue investigating as new information emerges.

Do I need to attend court or depositions?

Most cases settle before trial, so you may not need to testify in court. However, you will likely be deposed (questioned under oath by the other side’s attorney), and you may need to provide medical records and other documentation. Your attorney will prepare you for every step of the process and explain what to expect.

I'm a first responder or firefighter injured at the scene. Do I have a claim?

Yes. First responders injured while responding to industrial disasters may have claims beyond standard workers’ compensation or injury benefits. Contact us to discuss your situation.
