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 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.
