Which biosafety level is indicated for the suite?

• A. BSL-1
• B. BSL-2
• C. BSL-3
• D. BSL-4

Answer: (C)

Work with pathogens that can cause serious or lethal disease, especially via inhalation, requires containment beyond basic lab safety. BSL-3 is designed for that level of risk. It uses controlled access, directional airflow with negative pressure, and engineering controls like biosafety cabinets for aerosol-generating procedures. Personnel wear appropriate PPE and training plus medical surveillance is part of the setup, with strict decontamination and waste procedures. This level provides more protection than BSL-1 or BSL-2, which cover lower-risk organisms, but it isn’t as extreme as BSL-4, which is reserved for the most dangerous agents requiring full-body suits and separate facilities. So the suite is configured for BSL-3 containment.
