In a polyurethane production site, a foam block ignited on the conveyor belt on its way to the curing site. Since the fire was a threat to a depot, the fire-fighters and the staff evacuated the raw materials to another plant of the firm. The fire spread to the depot despite all efforts deployed by the fire-fighters. The highway near the plant was closed for 2 hours. The storage depot, two warehouses and 20 tonnes of polyurethane derived products were destroyed. Material damage amounted to 4.5 M DM. An industrial cleaning company pumped out the water used on fire coming from the foam facility. An electrostatic charge from lightning is believed to have triggered the accident.
