In the manufacture of medical equipment and equipment, in the production of pharmaceuticals and in the pharmaceutical sub-industry, certain conditions must be met in order to protect the product from microorganisms and particles and minimize the risks based on human health. These conditions depend on good recognition of the product, structuring and air-conditioning of the production area and the training and discipline of the personnel working in these areas. When looking at this type of production area with a clean room engineer, it is necessary to minimize the risk of direct and cross contamination in the planning stage, to prevent microorganism and dust accumulation and to ensure that the entire system is easy to disinfect and maintain. In addition, it is inevitable to ensure that the quality remains at the same level and that the possible mistakes can be backed up and controlled.
