Which BSL level is considered moderate risk in BEA operations?

• A. BSL-1 minimal risk
• B. BSL-2 moderate risk
• C. BSL-3 high risk
• D. BSL-4 extremely high risk

Answer: (B)

In biosafety, risk levels map to the level of containment needed. Moderate risk is handled at the level that provides BSL-2 containment. This level is used for agents that can cause human disease and are transmissible, but are typically treatable or preventable. The containment includes restricted access, biosafety training, and personal protective equipment such as gloves, lab coats, and eye protection. For procedures that may generate aerosols, a biosafety cabinet is used to prevent exposure. Surfaces and waste are decontaminated properly, often with autoclaving, and there are procedures for incident reporting and medical surveillance. These controls are sufficient to protect people and the environment while allowing work with these agents. That's why moderate risk in BEA operations aligns with BSL-2.
