Lubrizol factory fire in Rouen

The facility, subject to the Seveso-III Directive due to hazardous chemicals it stored and produced, created a large plume of smoke and led to a 500-metre (1,600 ft) exclusion zone.

While there were no fatalities, the fire caused elevated pollution levels, prompting containment measures and agricultural suspensions.

A thick plume of black smoke formed, reaching more than 20 km (12 mi), and a 500 m (1,600 ft) exclusion zone was imposed.

As part of the management of the accident, various measures were taken to protect the population (containment, school closures, suspension of certain agricultural activities, etc.).

[5] The direct economic consequences resulted from companies partially ceasing their activity and farmers that had to destroy their harvests.
