A devastating Washington paper mill explosion has left one person dead, nine workers missing, and several others injured after a massive chemical tank blast ripped through the Nippon Dynawave Packaging facility in Longview, Washington. The shocking incident at the Washington paper mill has triggered a major emergency response operation, with rescue crews continuing dangerous recovery efforts around the unstable chemical tank.
The chemical tank explosion at the Washington paper mill happened on Tuesday at the Longview facility operated by Nippon Dynawave Packaging, a subsidiary of Nippon Paper Industries. Authorities confirmed that the explosion involved a tank containing “white liquor,” a highly corrosive industrial chemical mixture used during paper pulp manufacturing.
The Washington paper mill explosion immediately caused panic across the industrial facility, sending emergency crews rushing to the scene as thick smoke and chemical hazards spread throughout the area.
What Happened at the Washington Paper Mill Explosion?
According to officials, the deadly explosion occurred after a massive chemical storage tank ruptured unexpectedly at the paper manufacturing plant in Longview, a city in Longview located roughly 45 miles north of Portland.
The ruptured tank reportedly contained “white liquor,” a dangerous chemical solution made from sodium hydroxide and sodium sulfide. The substance is commonly used in breaking down wood pulp during the paper-making process.
Initial reports suggested the tank held around 80,000 gallons of chemicals. However, authorities later revealed that the damaged structure may actually have contained nearly 900,000 gallons of white liquor. Officials further warned that about 90,000 gallons still remained trapped inside the unstable tank following the explosion.
The scale of the Washington paper mill explosion shocked emergency responders, especially after realizing the massive amount of hazardous chemicals involved.
9 Workers Missing After Deadly Nippon Dynawave Paper Mill Explosion in Washington
One Dead, Nine Missing After Chemical Tank Blast
Authorities confirmed that at least one person died in the Washington paper mill explosion, while nine others remain missing as rescue and recovery teams continue searching the dangerous site.
Nine additional people suffered injuries during the chemical tank blast. Officials stated that the injured victims included eight workers employed at the paper mill and one firefighter involved in the emergency response operation.
Some victims reportedly suffered serious chemical burns and trauma injuries following the explosion. The firefighter who was injured during the response operation received medical treatment and was later released from the hospital.
Emergency crews have been forced to move cautiously because the damaged chemical tank remains unstable and could collapse further at any moment.
Rescue Teams Face Dangerous Conditions
Recovery efforts at the Washington paper mill continued late into the night and are expected to continue further as officials monitor the unstable structure.
Matt Amos said rescue workers are operating under extremely hazardous conditions due to the remaining chemicals and the risk of structural failure.
Authorities have emphasized that although the Washington paper mill explosion was severe, there is currently “no direct threat” to the surrounding Longview community. Air quality and environmental monitoring teams have remained at the site to assess chemical exposure risks and ensure nearby residents remain safe.
Still, officials continue to monitor the paper mill carefully because any additional collapse of the damaged tank could worsen the situation dramatically.
Washington Governor Responds to Tragedy
Bob Ferguson expressed condolences to the victims and families affected by the Washington paper mill explosion during a media briefing following the incident.
The governor described the chemical tank blast as a heartbreaking industrial tragedy and thanked emergency responders for continuing dangerous rescue operations under difficult conditions.
Local officials also praised firefighters, hazardous materials teams, and medical responders who quickly arrived at the scene after the explosion rocked the paper manufacturing facility.
Nippon Dynawave Packaging Plant Background
The Longview paper mill operated by Nippon Dynawave Packaging employs around 1,000 workers and produces a wide range of paper products, including tissue paper, printer paper, cups, cartons, and paper plates.
The company became part of Nippon Paper Industries after the Japanese paper giant acquired the facility from Weyerhaeuser in 2016 for approximately $225 million.
The Japanese Consulate in Seattle reportedly confirmed that no Japanese employees were known to have been injured during the Washington paper mill explosion.
Previous Safety Concerns at the Longview Facility
This is not the first major industrial incident linked to the Longview paper mill.
In July 2023, the facility experienced another serious fire when massive wood piles caught fire and burned for several days, raising concerns about industrial safety and emergency preparedness at the plant.
The latest Washington paper mill explosion is now expected to trigger renewed scrutiny over chemical storage practices, industrial safety systems, and emergency response protocols at large manufacturing facilities across the United States.
Chemical Tank Explosion Raises Questions About Industrial Safety
The deadly chemical tank blast at the Washington paper mill has once again highlighted the risks associated with large-scale industrial chemical storage.
White liquor, while commonly used in pulp manufacturing, is highly corrosive and dangerous when released uncontrollably. Industrial experts say facilities handling such chemicals must maintain strict safety inspections, pressure monitoring systems, and emergency containment procedures.
As investigators continue examining the cause of the Washington paper mill explosion, authorities are expected to focus on whether equipment failure, structural weakness, maintenance issues, or operational errors contributed to the deadly blast.
For families waiting for news about the nine missing workers, the situation remains tense and heartbreaking as rescue crews continue searching through the hazardous wreckage at the damaged paper mill in Longview, Washington.
