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).
Biosafety level 4 laboratories are designed for diagnostic work and research on easily respiratory-acquired viruses which can often cause severe and/or fatal disease. What follows is a list of select agents that have specific biocontainment requirements according to US federal law.
The United States Centers for Disease Control and Prevention (CDC) categorizes various diseases in levels of biohazard, Level 1 being minimum risk and Level 4 being extreme risk. Laboratories and other facilities are categorized as BSL (Biosafety Level) 1–4 or as P1 through P4 for short (Pathogen or Protection Level). [citation needed]
Laboratories are assigned a biosafety level numbered 1 through 4 based on their potential biohazard risk level. [8] The employing authority, through the laboratory director, is responsible for ensuring that there is adequate surveillance of the health of laboratory personnel. [ 9 ]
