A biosafety cabinet —also called a biological safety cabinet or microbiological safety cabinet—is an enclosed, ventilated laboratory workspace for safely working with materials contaminated with pathogens requiring a defined biosafety level. Class II biological safety cabinets are primary engineering controls typically used for microbiological studies, cell culture, pharmaceutical procedures and toxicology. Class II Biosafety Cabinet Protection: • Personnel protection from harmful agents used inside the biosafety cabinet. • Product protection to avoid contamination of the work, experiment or process from outside contaminants. • Environmental protection from contaminants contained within the biosafety cabinet.

• A front access opening with carefully maintained inward airflow. • HEPA-filtered, vertical, unidirectional airflow within the work area. • HEPA-filtered exhaust air to the room or exhaust to a facility exhaust system.
