A hydrogen explosion at the Elkem Silicones facility in Saint-Fons, near Lyon, injured four employees on December 22, with two in critical condition. The blast triggered a fire and led to the activation of the Orsec emergency response plan, affecting over 100,000 residents who were advised to shelter indoors. The site, a high-threshold Seveso facility, has a history of safety issues, including a fatal accident in 2016.
