preamble_2928
4.3.2.3.3. During filling and discharge of tanks, battery-wagons and MEGCs, appropriate measures shall be taken to prevent the release of dangerous quantities of gases and vapours. Tanks, battery-wagons and MEGCs shall be closed so that the contents cannot spill out uncontrolled. The openings of bottom-discharge tanks shall be closed by means of screwthreaded plugs, blank flanges or other equally effective devices. The leakproofness of the closures of the tanks, and of the battery-wagons and MEGCs shall be checked by the filler after the tank is filled. This applies in particular to the upper part of the dip tube.
