BSL-1 is typically used in which setting?

• A. High school and community college labs
• B. Government facilities
• C. Biotechnology firms
• D. Hospitals

Answer: (A)

BSL-1 is the lowest biosafety level, designed for work with organisms that are not known to cause disease in healthy adults. In practice, this means standard teaching labs where students handle safe, non-pathogenic microbes or simple organisms. High school and community college labs commonly perform introductory microbiology activities at this level, because it allows hands-on learning with minimal risk and without specialized containment equipment. More advanced facilities—government laboratories, biotechnology companies, and hospitals—typically work with microbes or materials that require higher containment and stricter procedures (BSL-2 and above) due to potential health risks. Even at this level, basic safety practices like proper hygiene and PPE are followed to maintain a safe learning environment.
