Multiple people were killed and others remained unaccounted for after a major chemical explosion at a paper mill in Longview, Washington, on Tuesday. The blast occurred at 07:15 PDT at the Nippon Dynawave Packaging facility, located approximately 130 miles south of Seattle.
The explosion was caused by the rupture of a tank containing white liquor, a highly corrosive alkaline chemical used in the papermaking process that contains sodium hydroxide and sodium sulfide, according to a company statement. The tank holds about 80,000 gallons and was roughly 60% full when it ruptured, officials said.
Cowlitz Fire and Rescue Chief Scott Goldstein confirmed fatalities at the scene but said the exact number remained undetermined as of Tuesday afternoon. "We have confirmed that there are fatalities, but the exact number is undetermined," he told reporters during a news conference. Ten people were injured and transported to hospitals, including nine employees and one firefighter, with injuries ranging from critical severe to minor.
Washington Governor Bob Ferguson said state ecology workers had been deployed to assist local officials. "I'm deeply saddened to hear that there have been fatalities," Ferguson said in a statement. "My thoughts are with the workers and their families, and with the first responders."
What the Right Is Saying
Republican officials from Cowlitz County expressed condolences and emphasized the importance of allowing investigators to complete their work before drawing conclusions about causes or accountability. County Commissioner Paul Mitchell said local emergency responders had performed admirably under difficult circumstances. "Our first responders ran toward danger to save lives," Mitchell said in a statement. "We owe them our gratitude as we await the full picture of what happened."
Business groups noted that Nippon Dynawave is a major employer in the region and called for measured responses pending investigation results. The Washington State Association of Business said the company has been a long-standing member of the community. "Our thoughts are with everyone affected by this tragedy," the association said. "We await findings from safety investigators before any further comment."
Conservative commentators argued against what they characterized as premature regulatory overreach, noting that industrial accidents can occur even at facilities following proper protocols. Some pointed to California's simultaneous chemical tank incident in Orange County—where 50,000 people were evacuated—as evidence that such events are not unique to any particular safety philosophy.
What the Left Is Saying
Democratic lawmakers and labor advocates pointed to the incident as evidence of the need for stronger workplace safety enforcement. Senator Patty Murray of Washington called for a full investigation into whether federal OSHA standards were being followed at the facility. "Workers deserve to go home safe at the end of every shift," Murray said in a statement. "We must understand what went wrong and hold anyone accountable who failed to protect their employees."
Labor unions representing manufacturing workers urged caution before drawing conclusions but emphasized that chemical storage facilities should face rigorous inspection requirements. The International Brotherhood of Teamsters released a statement saying, "Every worker has the right to a safe workplace, period. Incidents like this underscore why we cannot allow regulatory agencies to be weakened."
Progressive advocacy groups noted that the Nippon Dynawave facility had previously faced safety concerns, pointing to a major fire at the same location in July 2023 when piles of wood burned for days. The Democratic-led Washington State legislature has previously considered bills strengthening chemical storage regulations near residential areas.
What the Numbers Show
The explosion occurred at a facility where a tank containing approximately 80,000 gallons (300,000 liters) of white liquor ruptured while roughly 60% full. Ten people sustained injuries requiring hospitalization, including nine employees and one firefighter. Officials have confirmed fatalities but declined to specify an exact number as search-and-rescue operations continued.
The Nippon Dynawave Packaging facility employs several hundred workers according to local employment data. The company is a subsidiary of Japan's Nippon Paper Industries. The site covers approximately 100 acres in Cowlitz County's industrial corridor, located near the Columbia River about 40 miles north of the Oregon border.
According to OSHA records reviewed by reporters, the facility received three safety inspections between 2020 and 2024, with no citations issued for serious violations during those reviews. The prior fire incident in July 2023 prompted an investigation that found no violations requiring corrective action.
Cowlitz County has a population of approximately 110,000 people. Longview's median household income sits below the state average, and manufacturing employment represents roughly 15% of local jobs, making the facility a significant economic contributor to the region.
The Bottom Line
The investigation into Tuesday's explosion at Nippon Dynawave Packaging is ongoing, with investigators working to determine how many people were killed and what caused the tank rupture. Officials have said the fire does not pose a threat to the larger community, and no evacuation order has been issued for surrounding areas despite continued firefighting operations.
State and federal workplace safety investigators are expected to examine whether existing protocols were followed at the facility. The incident is likely to reignite debates about chemical storage regulations in industrial zones near populated areas, though any policy changes would require legislative action that could take months or years.
Families of missing employees have been asked to contact emergency officials for information. The company said it is cooperating fully with investigators and will provide additional details as they become available.
