What do the Biosafety levels represent?
Biosafety levels have been described in detail in the publication “Biosafety in Microbiological and Biomedical Laboratories”, published by U.S. Department of Health and Human Services, Centers for Disease Control and the National Institutes of Health. General descriptions are: Biosafety Level 1 (BSL-1) is suitable for work involving well-characterized agents not known to consistently cause disease in healthy adult humans, and of minimal potential hazard to laboratory personnel and the environment. The laboratory is not necessarily separated from the general traffic patterns in the building. Work is generally conducted on open bench tops using standard microbiological practices. Special containment equipment or facility design are neither required nor generally used. Laboratory personnel have specific training in the procedures conducted in the laboratory and are supervised by a scientist with general training in microbiology or a related science. Biosafety Level 2 (BSL-2) differs from
