SAINT-FONS, Rhône – This afternoon, two significant explosions rocked the Elkem Silicones facility in Saint-Fons, a site classified as ‘Seveso high-threshold’ due to the hazardous materials it handles. The blasts, which occurred around 3:20 PM, led to the immediate deployment of a substantial emergency response, including firefighters, police, and specialized NRBC (Nuclear, Radiological, Biological, Chemical) units.
Emergency Response and Casualties
According to initial reports from Le Progrès, four individuals were injured in the incident, with two of them described as seriously hurt. Tragically, one person is still unaccounted for. The injured are believed to be employees of the Elkem site. In response to the severity of the situation, the Orsec plan, a French emergency response protocol, was triggered at 3:00 PM. A total of 35 firefighters and 13 vehicles have been mobilized to the scene, working to control the situation and search for the missing individual.
Site Details and Previous Incidents
The Elkem Silicones facility is a critical industrial site in the Rhône region, known for its production of silicones. Its ‘Seveso high-threshold’ classification indicates that it stores and handles large quantities of dangerous substances, necessitating stringent safety measures. This incident is not the first for the site; earlier this year, a leak of hazardous materials was reported at the same location, raising concerns about safety protocols and their effectiveness.
Community Impact and Road Closures
Following the explosions, a significant plume of smoke was observed emanating from the facility, prompting concerns among local residents. Authorities have activated the departmental operational center (COD) at the prefecture to coordinate the emergency response. A security perimeter of approximately 1,700 meters has been established around the Elkem plant, and road closures are anticipated as a precautionary measure to ensure public safety and facilitate emergency operations. Residents in the vicinity are advised to follow official instructions and avoid the area.
Ongoing Investigation and Future Steps
The immediate focus of the emergency services is to ensure the safety of the site, locate the missing person, and provide care for the injured. Once the immediate crisis is managed, a thorough investigation will commence to determine the cause of the explosions. This investigation will likely involve industrial safety experts, environmental agencies, and law enforcement to assess compliance with safety regulations and identify any potential failures. The incident underscores the inherent risks associated with high-threshold industrial sites and the critical importance of robust safety management systems.
Further updates will be provided as more information becomes available from the authorities.
