At around 11:30 a.m., a 32-tonne road tanker containing 30 m³ of propane fell over onto the shoulder of county road D6, on a slightly ascending left curve. The driver sustained minor injuries and was taken to hospital. A small leak was found on a valve of the tank. A 300 m safety cordon was put in place and traffic on the road was halted. The firefighters used water curtains, cooled the LPG tank, and partially patched the leak. However, a small flow of gas continued to leak out. The LPG was transferred to a backup vehicle from 6:40 p.m. until 12:20 a.m the following morning. The road tanker was then righted with a 130 tonne crane and taken to the depot of a subsidiary of the haulier. The firefighters reopened the road to traffic, then left at 3:30 a.m. The road tanker was damaged beyond repair and 15 m of crash barrier and telephone pole were damaged. According to the hazardous goods transport safety adviser, the accident was caused by the speed at which the vehicle was moving when entering the curve and the driver’s lack of training in driving a road tanker with robotised gearbox (it was only his second day). The haulier circulated an awareness-raising memo reminding drivers about road-safety rules and held a meeting with drivers about speed. In addition, all drivers must undergo training with an instructor who is present in the vehicle before being allowed to drive specific vehicles.
