Rosario, Argentina— An industrial chemical plant fire killed one worker and injured six others in Rosario on October 16, 2026, and the blaze sent thick black smoke over the southern industrial belt for hours. The fire started inside. It spread fast.
The Santa Fe Fire Department said the fire erupted around 10 a.m. in a storage area containing solvents and resins. An explosion was heard, then flames engulfed a warehouse. Workers ran. One did not make it out. Six others suffered burns and inhalation injuries.
A plant operator who escaped told Clarín, "We heard a pop, then fire everywhere. We tried to use extinguishers. It was too much." He had burns on his arms. The plant's internal brigade activated but was overwhelmed. Municipal firefighters took over.
Hazmat teams were deployed to monitor air quality. Neighbors within 300 meters were evacuated as a precaution. Schools closed windows. The plume was visible from downtown Rosario. Traffic on the Circunvalación was diverted.
A provincial labor ministry inspector said, "We are verifying safety protocols, storage permits, and whether workers had proper protective equipment. The company had prior observations." He declined to name the company pending family notification, but local media identified it as a paint and chemical manufacturer.
The injured were taken to Hospital de Emergencias Clemente Álvarez. Two are in serious condition with second-degree burns. The deceased worker, aged 42, was a maintenance technician with 10 years at the plant, according to union sources.
Clarín reported that industrial accidents in Rosario's southern zone have increased, with aging infrastructure and lax inspections cited by unions. Residents have complained about chemical smells for months. Complaints were filed.
By afternoon, firefighters controlled the blaze but continued cooling chemical drums. The site was sealed. The Labor Ministry ordered a preventive closure.
The investigation now focuses on whether flammable materials were stored improperly and whether electrical faults triggered the ignition. No official cause has been confirmed.
