On a logistics platform that included a 33,000-m² warehouse, fire broke out on an outdoor stockpile of wood pallets. The blaze was most likely sparked by friction of the metal fork on a forklift against the floor. Platform personnel were evacuated. The extremely high ambient temperatures very quickly fanned the flames to engulf storage areas, whose location at the site periphery allowed the fire to subsequently spread to neighbouring thatch fields, in threatening a residential subdivision. The response mobilised 125 fire-fighters and a major deployment of hydraulic resources (2 hydrants with a 250 m³/h flow rate), which by the end of the rescue mission had shown signs of vulnerability regarding the municipality’s water tower. First responders controlled the accident after a 3¼-hour battle and continued to monitor the situation through the following morning. As a result of this loss, a total of 3,200 empty pallets, 67 pallets of mineral water, 304 refrigerated containers and 17 stacks of cardboard were destroyed. Since on-site storage zones had been built entirely in concrete without a confinement basin, the 600 m³ of fire extinction water spilled into the facility network before entering the municipal storm drain network, which was connected to the RAMPENNE watercourse by a ditch. The inspection authorities for classified facilities noted the presence of blackish suspended particles, along with traces of hydrocarbons and a sizeable quantity of sludge in both the scrubber and ditch. The damaged concrete storage zones had been made vulnerable and were then covered by waste over several tens of m² (ash, partially consumed products). Given the risk of pollution by infiltration into the ground with pollutants being channelled by water, the inspection authorities for classified facilities proposed that the Prefect issue emergency notifications outlining several interim measures: scouring the networks and ditches through which the extinction water had flowed; covering storage zones followed by sludge analyses and disposal; discarding all ash and combustion residues; using safe operating practices around the accident zone; and lastly requesting a competent body to conduct a structural inspection. Moreover, a number of measures intended to mitigate the consequences of a potential accident were addressed in a supplemental executive order, calling for: adoption of an internal emergency plan, containment of fire water, installation of fire walls and a sprinkling network inside the warehouse, and removal of external storage zones from near the warehouses and the facility periphery.
