The Biosafety Cabinet (BSC) or microbiological safety cabinet is an enclosed, ventilated laboratory workspace for safely working with materials.
A Class I BSC is defined as a ventilated cabinet for personnel and environmental protection.
Class I BSCs protect workers but do not protect work products (such as specimens or cultures) against contamination because unsterilized room air is drawn over the work surface.
- Class I biosafety cabinets are typically used to either enclose specific equipment like centrifuges or for procedures like aerating cultures that might potentially generate aerosols.
- Biosafety cabinets of this class are either ducted (connected to the building exhaust system) or unducted (recirculating filtered exhaust back into the laboratory).
