Certified Healthcare Safety Professional (CHSP) Practice Exam

What is the primary characteristic of Biosafety Level 1 (BSL-1)?

1. Pathogens that cause disease in healthy humans

2. No known pathogenic potential to healthy humans

3. Requires full body protective gear at all times

4. Pathogens that are airborne and highly contagious

The correct answer is: No known pathogenic potential to healthy humans

The primary characteristic of Biosafety Level 1 (BSL-1) is that it involves microorganisms that pose a minimal risk to healthy humans and the environment. BSL-1 focuses on agents that are not known to cause disease in healthy adult humans. This level of biosafety is suitable for work with well-characterized agents that do not typically cause disease in humans. At BSL-1, the laboratory practices are simple, and standard microbiological practices are sufficient to ensure safety. While the other options mention various risks associated with pathogens, they do not accurately represent the scope of BSL-1 which is characterized by its low risk and the absence of disease-causing potential in healthy individuals. This understanding is crucial for effective laboratory safety and management practices, as it sets the foundation for more advanced biosafety levels that address increased risks associated with pathogenic microorganisms.
