A biosafety level (BSL), or pathogen/protection level, is a set of biocontainment precautions required to isolate dangerous biological agents in an enclosed laboratory facility. The levels of containment range from the lowest biosafety level 1 (BSL-1) to the highest at level 4 (BSL-4).
The levels of containment range from the lowest biosafety level 1 (BSL-1) to the highest at level 4 (BSL-4). In the United States, the Centers for Disease Control and Prevention (CDC) have specified these levels. [8] In the European Union, the same biosafety levels are defined in a directive. [9]
Not all select agents require BSL-4 handling, namely select bacteria and toxins, but most select agent viruses do (with the notable exception of SARS-CoV-1 which can be handled in BSL3). Many non-select agent viruses are often handled in BSL-4 according to facility SOPs or when dealing with new viruses closely related to viruses that require BSL-4.
BSL-4 cabinets and "Suit Laboratories" have special engineering and design features to prevent hazardous microorganisms from being disseminated into the outside environment. These biosafety suites , where PPPSs are used, are suites of laboratory rooms which are essentially equivalent to large Class III biosafety cabinets in which the interiors ...
