Upon completion of works authorised under a hot work permit in a tyre factory, technicians performing organisational work observed a fire outbreak at the outlet of a smoke extractor. Hot particles generated during the works had ignited some dust. Technicians notified the control room at 3:15 pm. A pair of internal fire-fighters using the nozzle of a fire hose caused a few pieces of ignited dust to fall. Public fire-fighters was called at 3:25 pm. A second pair of in-house responders entered from the roof to extinguish the flames and then used a fire nozzle to cool the top and cover of the extractor. Upon arrival of the external first responders at 3:40, the fire had already been brought under control. Fire-fighters inspected around the extractor by removing the roof and glass wool while cooling, then left the site at 5:50 pm, recommending that a team of two internal fire-fighters remain stationed onsite until a subcontractor relined the roof. Activity resumed in this zone at 6:15 pm, once the roofing company had left the premises. This incident caused no injuries or property damage. The next day, a worker was burned by vapour when changing a coupling without first closing the shut-off valves (ARIA 30683).
