A biosafety cabinet provides protection for which aspects when handling hazardous biological materials?

• A. Personnel, product, and environment
• B. Equipment only
• C. Laboratory budget
• D. Data integrity

Answer: (A)

The main idea here is containment and controlled airflow that shields three things at once: the person using the cabinet, the material being handled, and the surrounding room. A biosafety cabinet draws room air through a front grille and passes it through HEPA filters, creating a controlled airflow pattern that confines aerosols and spills within the work area. This setup protects the worker by capturing any hazardous particles inside the cabinet, protects the product by delivering clean, contaminant-free air to the work surface and preventing contamination of samples, and protects the environment by filtering and containing the exhaust air so no hazardous material escapes into the room. Budget or data integrity aren’t the cabinet’s protective roles.
