A security perimeter was set up by fire fighters / authorities. The road, as well as the parallel roads,was cut in both ways of traffic. A diversion was organized.Fire brigades quickly mastered the fire. They also verified the state of gas cylinders. Those not leaking were cooled, those leaking were left burning in a controlled way. The evolution of the fire was followed by a thermography (thermal camera). It was estimated that the fire burned at a temperature superior to 2000C.The following morning, several bottles had finished burning, four were still closed and two others remained wedge under the truck. Fire brigades continued to splash the cylinders with water to cool them, before being able to analyse the situation more in detail. One day later, the fire was totally under control by fire brigades, further hazards involving cylinders were excluded, and the operations of clearing were able to begin. Three days later, the crisis unit met and decided to open again a part of the road in the traffic in both ways. The traffic was disrupted during approximately one week because of renovation work.
