Which feature is characteristic of Biosafety Level 2 (BSL-2) laboratories?

Restricting access to trained personnel is a defining feature of a BSL-2 setting. These labs handle agents that can cause illness in healthy people but aren’t among the most dangerous pathogens, so entry is limited to individuals who have received proper safety training and follow standard microbiological practices. This access control helps prevent accidental exposure, especially if a spill or splash occurs. In practice, you’ll also see PPE like lab coats, gloves, and eye protection, and procedures that could generate aerosols are performed in biosafety cabinets. The presence of guidelines, training, and designated entry points isn’t optional here.
