Abstract: Retention system and method for preventing the efflux of substances from installations into the surroundings A retention system is described for collecting substances from installations. This comprises at least one outlet line which opens out into at least one flexible container and is joined in an essentially pressure-tight manner and to this which is equipped with a pressure-relief safety device and which serves for pressure relief and for conducting away substances from the installation. The flexible container must be dimensioned at least so that in the filled state it has an internal volume such that the internal pressure of the joint system of outlet line and flexible container virtually corresponds to the external pressure. In addition, a method for avoiding the efflux of substances from installations into the surroundings is described. This comprises the steps: a) conducting away the substances from the installation by means of at least one outlet line which serves for pressure relief and for conducting away substances from the installation, b) introducing the substances into at least one flexible container which is joined to the outlet line, the flexible container being selected 80 that in the filled state it has an internal volume which is at least such that the internal pressure of the joint system of outlet line and flexible container virtually corresponds to the external pressure, and c) intermediate storage of the substances in said flexible container up to proper disposal.
