A petrol leak occurs while a tank is being filled at a supermarket service station. To reduce the fill time, the deliveryman moves his truck in order to hook up to another tank 10 metres away, but he misjudges the distance (night time, bad weather) and this places severe stress on the tube, causing sudden rupture of the tank valve. He activates the shut-off valve, but 1000 litres of fuel spread to the low points, manholes and pipes in the shop parking lot. Firemen set up a safety barrier and place absorbent products throughout the affected area. A specialised company cleans the site the following day. No pollution is found. The operation carried out after closing the shop kept the accident from becoming more serious. The administration finds that the station’s facilities are not in compliance with regulations (transfer area, spill prevention). A safety instruction must be established.
