Biosafety levels (BSLs) are a series of protections designed to mitigate the risk of exposure to infectious agents. In histology labs, adhering to the appropriate BSL is crucial to prevent laboratory-acquired infections:
BSL-1: Suitable for work with well-characterized agents not known to cause disease in healthy adults. BSL-2: For work with agents that pose moderate hazards to personnel and the environment. BSL-3: Applies to work with agents that can cause serious or potentially lethal disease through inhalation. BSL-4: For work with dangerous and exotic agents that pose a high risk of life-threatening disease.
