Which option is NOT a characteristic of Biosafety Level 2 laboratories?

• A. Work with pathogens moderate in hazard
• B. Conducive for a variety of diagnostic tests
• C. Absence of human transmissible diseases
• D. Adequate interventions available for exposure

Answer: (C)

Biosafety Level 2 (BSL-2) laboratories are designed to handle pathogens that pose a moderate risk to personnel and the surrounding community. One key characteristic of BSL-2 labs is that they deal with pathogens that can cause diseases in humans, and some of these pathogens can indeed be transmissible between humans. Therefore, the assertion that there is an absence of human transmissible diseases is not accurate for BSL-2 environments. In contrast, the other characteristics reflect the standard practices found in BSL-2 laboratories. These facilities work with moderate hazards, allowing for a variety of diagnostic tests. They are equipped with adequate interventions and safety protocols to manage potential biosafety risks, ensuring that personnel handling these pathogens have protective measures in place. Thus, the option indicating an absence of human transmissible diseases does not align with the definition and function of BSL-2 labs.
