Biotechnology. Laboratories for research, development and analysis. Containment levels of microbiology laboratories, areas of risk, localities and physical safety requirements Ingestion-build-59651 and the efficiency of extraction1 Scope This European Standard specifies minimum physical requirements for biological safety for laboratories at four reference physical containment levels which are appropriate for handling micro organisms of different risk groups. This European Standard primarily addresses the containment of micro organisms which can present a risk to human health. It applies to microbiology laboratories where the handling of micro organisms in bacteriology,
