Final answer:
The appropriate biosafety level for a clinical microbiology laboratory working with potentially airborne pathogens like tuberculosis bacteria is BSL-3.
Step-by-step explanation:
The appropriate biosafety level for a clinical microbiology laboratory working with potentially airborne pathogens like tuberculosis bacteria is BSL-3.
BSL-3 agents have the potential to cause lethal infections by inhalation. Laboratories working with BSL-3 agents require restricted access and strict safety precautions to protect laboratory workers and prevent the spread of infectious agents. These precautions include wearing respirators, working in a biological safety cabinet, and having specialized facilities with directional airflow.
Examples of BSL-3 agents include Mycobacterium tuberculosis and Bacillus anthracis.
