One person has been confirmed dead while nine others remain missing following the implosion of a massive chemical storage tank in Washington, authorities said as emergency crews continued search and rescue operations.
The incident occurred at an industrial facility where a 3.4-million-litre chemical tank reportedly collapsed during maintenance operations, triggering a powerful explosion and widespread structural damage.
Emergency officials said several workers were at the site when the tank imploded, trapping some beneath debris and forcing nearby evacuations due to concerns over hazardous materials.
Local fire and rescue agencies deployed specialised teams to search the area, while hazardous materials experts monitored air quality and chemical exposure risks around the facility.
Authorities confirmed that one body had been recovered, while efforts were ongoing to locate the remaining missing workers.
“We are doing everything possible to find those unaccounted for and ensure the area is safe,” an emergency official told reporters during a briefing.
The exact cause of the implosion has not yet been determined, though investigators said preliminary inquiries would focus on possible equipment failure and industrial safety procedures.
Residents living near the site were advised to avoid the area as emergency crews worked to contain the situation.
Officials said no immediate large-scale environmental contamination had been detected, but monitoring operations would continue until the site is fully secured.
The Occupational Safety and Health Administration and other federal agencies have launched investigations into the accident.
The explosion has renewed concerns about industrial safety standards in chemical storage facilities across the United States, particularly involving ageing infrastructure and hazardous materials handling.
Labour unions and safety advocates called for stricter oversight and improved protections for industrial workers following the incident.
The affected facility has suspended operations pending the outcome of investigations and recovery efforts.
Authorities said rescue operations may continue for several days due to the scale of the damage and the unstable condition of parts of the site.
