Which biosafety level is described as a basic laboratory?

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

Answer: (A)

Working with the lowest containment level means handling organisms that are not expected to cause disease in healthy people, using standard lab practices and minimal personal protective equipment. This basic laboratory setup has no specialized containment equipment or restricted-access facilities—work is typically done on open benches with a lab coat, gloves, and eye protection as needed. It’s suitable for nonpathogenic strains and routine educational or basic diagnostic tasks. Higher levels introduce more controls—restricted access, additional PPE, use of biosafety cabinets, negative pressure rooms, and, in the highest level, full-body protective suits—so they are not considered basic laboratories.
