A liquefied gas leak occurs at a petrol station on Friday at 5:30pm; the contents of a tank truck, i.e. some 9000 litres spill onto the ground when a pipe bursts. The explosivity measurements taken show 100% LEL in some places. A residence adjacent to the station is evacuated (2 renters) and a safety barrier is set up around this residence and the station. The next morning, the owner opens the station against the recommendations of the emergency responders. The town hall issues an order to close the station, which is delivered by the police force (gendarmerie). The next day at noon, a patrol reads values of between 1 and 2% LEL at the external opening, but still 100% at the openings near the filling area. That evening, the measurements do not show significant levels. The ground is to be analysed before the operator reopens the station in order to ensure that no product remains in the ground.
