What Does BSL Stand For?
BSL stands for Biosafety Level
BSL, or Biosafety Level, refers to a set of classifications that define the containment measures required to safely work with biological agents in a laboratory setting. These levels range from BSL-1 to BSL-4, with each level indicating the risk posed by the agents and the corresponding safety protocols necessary to protect laboratory personnel, the environment, and the public. BSL-1 represents minimal risk, while BSL-4 denotes the highest level of containment for the most dangerous pathogens.
