The invention relates to a method for detecting and preventing leaks of a double-walled container (2) for the storage of poisonous, caustic, irritant and/or combustible media, wherein the double-walled container (2) has an inner wall (3) and an outer wall (4), wherein a cavity (5) is formed between the inner wall (3) and the outer wall (4), wherein a positive pressure is generated in the cavity (5), wherein, in the event of a leak of the inner wall (3), a gas is fed to the cavity (5) in order to maintain a positive pressure in the cavity (5), and to a corresponding container system (1) having an open-loop/closed-loop control device for the open-loop/closed-loop control of a gas throughflow in a line (8) and having a pressure measuring unit (11) for measuring the pressure in the cavity (5) of the double-walled container (2).
