A catastrophic chemical explosion occurred at the Nippon Dynawave Packaging paper mill in Longview, Washington, on Tuesday morning, resulting in multiple deaths and numerous critical injuries. The incident took place around 7:15 a.m. local time when a tank containing approximately 48,000 gallons of 'white liquor'—a chemical essential to the paper production process—ruptured. The tank had a total capacity of 80,000 gallons and was about 60 percent full at the time of the rupture.
Casualties and Emergency Response
Officials confirmed multiple fatalities, though an exact number has not yet been released. Nine workers and one firefighter were initially transported to local hospitals for treatment. The firefighter has since been discharged, but the condition of the other victims remains critical. First responders, including a specialized hazmat team, arrived swiftly at the scene to contain the chemical spill and provide medical assistance. As of Tuesday afternoon, authorities were still searching for individuals who remained unaccounted for, raising concerns that the death toll could rise.
Local hospitals have activated emergency protocols to handle the influx of patients, and trauma counselors have been dispatched to support affected families and employees. The Cowlitz County Emergency Management Agency is coordinating with state and federal agencies to manage the aftermath.
Community Safety and Investigation
While officials have assured the public that there is no immediate threat to the broader community, they have urged residents to avoid the area surrounding the mill to allow emergency crews to work safely. The cause of the tank rupture is under investigation, with early reports suggesting a possible structural failure or operational error. The Occupational Safety and Health Administration (OSHA) has been notified and will conduct a thorough inquiry into the incident.
Nippon Dynawave Packaging, a subsidiary of Japanese company Nippon Paper Industries, has expressed condolences and pledged full cooperation with investigators. The mill, which employs hundreds of workers, has been temporarily shut down. This tragedy marks one of the deadliest industrial accidents in Washington state in recent years, prompting renewed calls for stricter safety regulations in chemical handling facilities.
