Which statement correctly associates BSL-3 and BSL-4 with the types of facilities described?

• A. Government facilities
• B. Small family clinics
• C. Primary school labs
• D. Community centers

Answer: (A)

High-containment labs use sophisticated containment features and strict procedures to protect people and the environment. BSL-3 and BSL-4 are levels for work with dangerous pathogens that can cause serious or lethal disease, requiring negative-pressure rooms, dedicated airflow, sealed access, decontamination systems, and personnel trained in biosafety and emergency response. Because of this extensive infrastructure and regulatory oversight, such high-containment facilities are typically housed in government or national research institutions rather than in ordinary clinics, schools, or community centers. So the statement linking BSL-3 and BSL-4 to government facilities best fits how these biosafety levels are used.
