Question
The biosafety level (BSL) for a clinical microbiology laboratory working with potentially airborne pathogens, such as tuberculosis bacteria, isGroup of answer choicesBSL-1.BSL-4.BSL-3.BSL-2.
Solution
The correct answer is BSL-3.
Biosafety Level 3 (BSL-3) is appropriate for work involving microbes which can cause serious and potentially lethal disease via the inhalation route. This type of laboratory has special engineering and design features to prevent microorganisms from being disseminated into the environment. Workers wear protective clothing and respiratory protection, and there are special methods for waste disposal, ventilation, and access to the laboratory. Tuberculosis bacteria, which can be airborne and cause serious disease, would be handled in a BSL-3 laboratory
