A tank rupture at the Nippon Dynawave Packaging Company in Longview, Washington, killed several workers and left dozens with critical injuries on Tuesday morning. The incident occurred just before 7:30 a.m., prompting an emergency response from the Longview Fire Department and hazardous‑materials crews. The plant, owned by Nippon Group, employs 800 staff.

Authorities confirmed fatalities and multiple severe burns, sending victims to PeaceHealth St. John in Longview and PeaceHealth Southwest in Vancouver. The tank held white liquor, a sodium‑sulfide and sodium‑hydroxide mixture that operates under high pressure and temperature. Fire officials warned residents to avoid the site near the Columbia River, noting no immediate threat to the public. Several patients remain in intensive care.

The Longview mill, which supplies wood pulp and paperboard for packaging, has a history of safety incidents, including a 2023 blaze that spiked air‑quality alerts in Portland and a 2025 locomotive‑shop fire. Repeated disruptions raise concerns for customers and creditors, potentially tightening credit lines seriously and prompting supply‑chain diversifications across the North‑west packaging sector.
