A tank containing ROGOR (dimethoate in solution in cyclohexanone) exploded and caught fire. Two fragments passed through the unit and control room, injuring 2 employees. The fire was rapidly brought under control and the population, worried about the potential consequences, began to flee the area. Although 6,000 m³ of firefighting water was recovered in the storage unit’s retaining catchpit, the accident nevertheless polluted a river and the coastal area, leading authorities to restrict swimming over 15 km. Precautions were taken with regard to the consumption of local fruits and vegetables. This accident was caused by the instability of the products.
