Biosafety Level Page

Biosafety levels (BSL) are a series of protections and precautions implemented in laboratory settings to protect workers, the environment, and the public from infectious agents. Established by the and the National Institutes of Health (NIH) , these four levels are determined by the infectivity, severity of disease, and transmissibility of the microbes being studied. The Four Biosafety Levels

The containment requirements increase as the risk of the biological agent rises, ranging from BSL-1 (lowest risk) to BSL-4 (highest risk). Biohazard Levels - StatPearls - NCBI Bookshelf biosafety level
