This European Standard specifies minimum physical requirements for biological safety for laboratories at four reference physical containment levels which are appropriate for handling microorganisms of different risk groups. This European Standard primarily addresses the containment of microorganisms which can present a risk to human health. It applies to microbiology laboratories where the handling of microorganisms in bacteriology, mycology, virology, parasitology and/or genetic modification is carried out.
