Which BioSafety Level is designated for agents that pose minimal risk to laboratory personnel and the environment?

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

Answer: (A)

The designation of BioSafety Level 1 (BSL-1) is appropriate for agents that pose minimal risk to laboratory personnel and the environment. This level is primarily concerned with studies involving well-characterized agents that are not known to consistently cause disease in healthy adult humans. The recommended practices at BSL-1 include standard microbiological techniques, which means that routine laboratory practices are sufficient to ensure safety. Facilities handling BSL-1 agents typically do not require special engineering controls or containment measures, and work can be conducted on open bench tops. This level allows for a foundational understanding of biosafety, emphasizing the need for good laboratory practices, personal hygiene, and basic sanitation without the need for advanced protective measures that are used in higher Biosafety Levels.
