An inspection contractor found a chemical tank at a Washington state paper mill \u201cnot fit for continued service\u201d 10 months before it failed in May, killing 11<\/a> in one of the deadliest U.S. workplace disasters in recent decades, according to a federal report released Friday.<\/p>\n

The U.S. Chemical Safety Board\u2019s update about the May 26 failure<\/a> in Longview, which expelled enough caustic liquid to blow out building walls, is part of an ongoing investigation. The federal agency said it is still determining the cause of the failure.<\/p>\n

The board found that the contractor provided Nippon Dynawave Packaging Company with recommendations for internal inspections and shell repairs, but the company did none between a July 2025 inspection and the May 2026 failure.<\/p>\n

\u201cBecause the investigation remains ongoing, we will not comment on individual findings or documents at this time,\u201d an emailed statement from Nippon spokesperson Sam Jefferies said Friday. \u201cOur focus remains on supporting affected families and employees and taking the necessary steps toward fully reopening the Longview facility.\u201d<\/p>\n

Jefferies said the company will continue to cooperate fully with the board.<\/p>\n

The Association of Western Pulp and Paper Workers released a statement on Friday saying the board\u2019s findings were \u201cdeeply troubling.\u201d<\/p>\n

\u201cThe update raises urgent questions about how technical findings and recommendations concerning the tank were communicated, evaluated and incorporated into decisions about its continued operation,\u201d the statement said. \u201cThe families and workforce deserve a complete accounting of that process.\u201d<\/p>\n

Lawyer for family of 2 brothers who died says accountability is needed<\/p>\n

A lawyer representing the family of two brothers who were killed, Tyler and Bradley Covington, said the board\u2019s findings are \u201cnothing short of alarming.\u201d<\/p>\n

\u201cWhen safety inspections and recommendations don\u2019t lead to action, danger becomes a reality that causes devastation to human life,\u201d lawyer Kyle Findley said in a statement Friday. \u201cWe will continue to work tirelessly to ensure those responsible for this horrific accident are held accountable and their families receive justice.\u201d<\/p>\n

Democratic U.S. Sen. Patty Murray said in a statement that the community deserves answers and \u201cevery worker has the right to come home safely at the end of the day.\u201d<\/p>\n

Multiple inspections found safety problems before tank failure<\/p>\n

In July 2025, the contractor found \u201csignificant thinning\u201d below the minimum safe thickness in the lower regions of the tank after an external inspection, according to the board\u2019s report. The minimum safe thickness is a threshold that measures a tank\u2019s ability to contain the pressure of the liquid and support the tank\u2019s weight, the report said.<\/p>\n

The same contractor inspected the exterior of the tank in October 2025 and February 2026 and both times identified that \u201clarge portions of the tank remained thinner than the calculated minimum safe wall thickness.\u201d <\/p>\n

\u201cThe company also did not remove the tank from operation or derate the tank for reduced service,\u201d the board said. <\/p>\n

The tank failure released roughly 900,000 gallons (3.4 million liters) of a liquid known as white liquor that is used to break down wood for making paper products and is capable of causing severe burns. In addition to the workers killed, several others and one firefighter were injured.<\/p>\n

Official questions why paper company didn\u2019t act<\/p>\n

The board\u2019s Chairperson Steve Owens said in a statement \u201cwe are greatly concerned that the tank was not promptly removed from service or properly repaired after the clear findings in the inspection report.\u201d<\/p>\n

In an excerpt of the July 2025 inspection included in the board\u2019s update, the recommendations were noted as \u201cPriority 1: Not fit for continued service unless corrected,\u201d with a \u201chigh likelihood\/consequence of failure (or) critical code\/standard deficiency.\u201d<\/p>\n

\u201cOwner should plan to have an internal inspection performed in order to determine the extent of the required repairs. It\u2019s likely that the entire shell course should be replaced,\u201d the inspection excerpt says. <\/p>\n

The inspection was completed by Applied Technical Services LLC. The federal report did not specify why the company was conducting the inspections.<\/p>\n

Tank failure occurred as employees started to arrive to work<\/p>\n

The catastrophic failure hit just minutes after employees began arriving around 7 a.m., the board\u2019s report said.<\/p>\n

Shortly before 2 a.m., a vessel at the facility called a digestor was removed from service for repairs. As a result, the tank stopped sending white liquor into the digestor. But more white liquor continued to flow into the tank, causing it to approach full capacity around 6:20 a.m. It failed less than an hour later, the report said.<\/p>\n

After flooding the courtyard, crushing vehicles and destroying part of one of the surrounding buildings, the liquid flowed into the buildings\u2019 lower floors, where workers were holding morning meetings.<\/p>\n

All eight workers in the electrical maintenance shop as well as a worker in the courtyard were killed. In the mechanical maintenance shop, five employees and the foreman escaped, but two were killed from exposure to the chemical, the report said. Two of the people who escaped were seriously injured due to chemical burns.<\/p>\n

The company radioed for its medical emergency response team but didn\u2019t explain that white liquor had been released, according to the report. A member of the team waded into a pool of white liquor to try to rescue an employee, thinking it was water, and was seriously injured from chemical burns.<\/p>\n

Earlier this week, the Washington Department of Ecology issued notice of 35 environmental violations to Nippon Dynawave. The state agency oversees the facility\u2019s air and water quality permits and compliance with environmental waste laws.<\/p>\n

The board said its investigation is ongoing and that its complete findings will be included in its final investigation report.<\/p>\n
