Abstract: A safety device for a single-use mixing or storage system (10), especially for use in a biopharmaceutical process, includes a flexible bag (12) made from a film material and a support structure (14) receiving and supporting the bag (12) in several directions. The support structure (14) allows an expansion of the bag (12) in an expansion direction. The safety device further includes a detection unit (20) adapted to detect an expansion of the bag (12) in the expansion direction, and a control unit (28) connected to the detection unit (20) and adapted to initiate a safety measure in response to the expansion of the bag (12) in the expansion direction exceeds a given threshold.
