Biosafety in Microbiological and Biomedical Laboratories

The BMBL describes the combinations of standard and special microbiological practices, safety equipment, and facilities constituting Biosafety Levels 1-4, which are recommended for work with a variety of infectious agents in various laboratory settings.

The advisory recommendations are intended to provide a voluntary guide or code of practices as well as goals for upgrading operations. They are also offered as a guide and reference in the construction of new laboratory facilities and in the renovation of existing facilities.
