<p>The invention relates to a device for monitoring leakage for long durations, especially for use in flat tank structures, having a sensor cable arranged on the exterior side of the tank casing. A collection chamber is provided at least partially underneath the base of the flat tank structure and preferably surrounds said tank structure on the outer circumferential side thereof in an annular manner. The collection chamber is connected to the lower end of the exterior side of the tank casing via a flange having a slope. The sensor cable is arranged on the flange or in the base area of the collection chamber. According to the invention, a fire indication sensor is located above the collection chamber. In the case of a fire, said fire indication sensor triggers an automatic foaming of the collection chamber by interacting with a fire extinguishing means.</p> |
