Five years after the catastrophic fire at the Lubrizol chemical plant in Rouen, France, the community continues to grapple with its aftermath.

The blaze, which erupted on September 26, 2019, engulfed 9,500 tonnes of hazardous materials, leaving a trail of environmental and health concerns.

Despite efforts to seek justice, the cause of the fire remains undetermined, complicating legal proceedings.

The incident has spurred calls for stronger safety regulations, including the establishment of a Seveso site safety authority to prevent future disasters.

Meanwhile, the tragedy has paradoxically accelerated ecological transitions in the region, prompting public and private sectors to reassess risk management and environmental protection strategies.

As Rouen rebuilds, the memory of the black smoke and its implications linger, urging continuous vigilance and reform.
