A violent thunderstorm caused several incidents at an industrial site. The general electricity distribution station was struck by lightning that resulted in many electrical disturbances in particular the loss of equipment, the protection of several installations and, consequently, flare releases for a few hours. Just after sundown, two fires broke out, one on a pump packing the other on a heat-insulated line without any consequence whatsoever being recorded. Moreover, the site’s treatment plants had to face a sizeable quantity of water inflow, necessitating the installation of floating dams on the nearby pond opposite the plant’s outfalls.
