During dismantling of a disused facility, which had formerly been devoted to collecting and filtering polishing dust and set up in an unoccupied room, some polishing residue (composed of tallow + aluminium dust + abrasives) contained in a concrete pipe ignited. A welding torch used to cut the bolts of piping fastened to the ground, a task typically contracted out, would have caused the fire. The personnel were not able to extinguish the blaze, but firefighting crew called onto the scene subsequently controlled the incident, which at no time threatened to spread beyond 4 meters of pipe length.
