Fire broke out around 7 am in a varnishing booth at a former wood furniture factory. The site had been shut down for several months and all buildings on the site evacuated, except for the varnish drying furnace. The company itself was installed in premises of a former paper factory for sanitary use. Dust from cellulose wadding and paper, accumulated between the floor boards and tiles, helped spread flames to the 4,000 m² of roof space. Some 50 fire-fighters set up 5 nozzles inside the building and outside another 2 large nozzles assembled on tall ladders. Given the presence of several tonnes of asbestos on the roof, they intervened wearing self-breathing apparatuses, confined neighbours indoors and installed foam nozzles in order to bring down the toxic smoke. A specialised team sliced the roof over a 30-m length to prevent the flames from spreading. The fire was brought under control at 10:30 am and completely extinguished shortly before 2 pm. Notified by neighbours and fire-fighters fearing pollution caused by the extinction water and questioning the building’s gas supply cut-off, the Classified Facilities Inspectorate visited the site.
