What describes a bio-safety level 1?

• A. Conditions involving minimal risk to laboratory personnel
• B. Handling of organisms known to cause serious disease
• C. Protocols for dealing with airborne pathogens
• D. Environment requiring full body protective gear

Answer: (A)

A bio-safety level 1 (BSL-1) is characterized by working with well-defined and non-pathogenic organisms that pose minimal risk to laboratory personnel and the environment. In this level of containment, laboratories typically operate with standard microbiological practices, and no special containment equipment is necessary. Facilities working at this level may include teaching laboratories or research facilities focused on non-infectious strains of microorganisms—such as certain strains of yeast, non-pathogenic E. coli, and other similar organisms. The work does not typically involve risks of infection or other serious health consequences for laboratory workers, which aligns perfectly with the description of minimal risk. In contrast, the other options relate to higher levels of bio-safety. For example, handling organisms that can cause serious disease typically requires BSL-2 or higher environments, while airborne pathogens and the requirement for full body protective gear are associated with BSL-3 and BSL-4 protocols. Thus, the correct description of BSL-1 aligns with the focus on minimal risk to personnel.
