How is my product categorized? What processes and procedures are commonly used? Which room classifications are available? These and many other questions are a first baseline to start with. Maintaining aseptic barriers When transferring products between different classified areas, the most important point is to maintain the aseptic barrier. Transfer systems and procedures are just as variable as the types of barrier systems. Hence, there are many different ways of bringing products and materials into barrier systems. A general distinction can be made between continuous (e.g. mouse hole, e-beam, sterilizing tunnel) and discontinuous transfer systems (e.g. rapid transfer ports, airlocks, liquid transfer systems). Besides many other sources, an important reference is ISO 14644. Since aseptic risk assessment also plays an important role, ISO 13408 is also worth considering.
