Which biosafety level is the most basic level of containment and there is no risk to personnel?

• A. 1
• B. 2
• C. 3
• D. 4

Answer: (A)

This is Biosafety Level 1. It’s the most basic containment level, used for well-characterized, nonpathogenic organisms that pose minimal risk to healthy adults. At this level standard microbiological practices are sufficient, and no specialized containment equipment is required. Personal protective equipment is minimal—often just a lab coat and gloves as needed—and good hygiene and routine decontamination practices help prevent exposure. Higher biosafety levels are reserved for organisms that can cause disease or pose greater risks and require increasingly stringent controls such as enhanced PPE, engineering controls, and restricted facility features.
