Washington chemical plant disaster

Overview

A leak from an 80,000‑gallon tank at the Nippon Dynawave Packaging plant in Longview, Washington was first reported on 27 May 2026, killing one worker and injuring ten people. The incident was described as a hazardous‑materials emergency, with officials stressing no immediate danger to the surrounding public.

Later that day, authorities updated the casualty figures: two workers had died and nine were missing, with ten people taken to hospitals for severe chemical burns. The ruptured vessel held "white liquor," a caustic alkaline solution used in pulp production, and tens of thousands of gallons entered the Columbia River, though drinking‑water and air‑quality risks were deemed low.

By 29 May, the death toll was revised again as eight workers were confirmed dead and three remained missing. Environmental officials reported river contamination but no immediate threat to the city’s water supply. State and federal investigators launched safety and cause investigations.

On 31 May the missing workers were recovered, bringing the confirmed death count to eleven. The collapse released roughly 900,000 gallons of the caustic solution, contaminating the Columbia River but not affecting local air quality or drinking water. The plant, a subsidiary of Japan’s Nippon Paper Industries, faced intensive scrutiny over hazardous‑material storage practices.

Follow‑up reports on 30 May and 2 June confirmed the eleven fatalities, detailed the chemical composition (sodium hydroxide and sodium sulfide), and noted that families were seeking legal counsel. Insurance brokers reported a surge in inquiries from similar facilities about pollution and liability coverage, underscoring the broader industry impact of the disaster.
