In a kitchen utensils factory, a dust fire broke out around 9:50 am on one of the polishing unit’s brushes and then spread into suction ducts of the dust removal system. Personnel working in this unit and adjoining workshops were evacuated and external first responders notified. Electricity supply was cut, thereby halting suction system operations. The company’s thermal camera made it possible to quickly localize the second hotspot at the level of a duct elbow. Efforts to fight the two fire outbreaks involved at first extinguishers and then the fire protection system by the plant’s fire-fighting team, before some 15 external responders completed the task. In all, 200 to 300 litres of water were used. No injuries were reported. Property damage could be limited thanks to staff reactivity, the type of ducts (metal), their relative cleanliness (summer maintenance), and a dust treatment by wetting. Operations started back up that same afternoon on other installations. According to initial observations, a hard spot or heating of the brush due to cooling malfunction was a possible cause of this incident. The operator ordered an investigation. In order to facilitate emergency response, the operator planned to install additional hatches on the facility’s dust removal pipelines as well as replace the wing nuts on existing hatches by quick-opening fasteners.
