A Biological Safety Cabinet (BSC) serves as the primary means to protect the laboratory worker and the surrounding environment from pathogens. All exhaust air is HEPA-filtered as it exits the biosafety cabinet, removing harmful bacteria and viruses. BSCs are designed to provide personnel, environmental and product protection when appropriate practices and procedures are followed.

Certifications, Maintenance or Service

The Institutional Biosafety Committee – Biosafety Cabinets, Animal Transfer Stations, and Clean Air Devices Policy (IBC-POL-18) lists requirements for the certification, use, and maintenance of these containment equipment. Biological Safety Cabinets must be certified when initially purchased and installed. Annual certification is required unless it is waived annually by the Office of Biological Safety (OBS), which is considered on a case-by-case basis for low-risk activities.  Waived BSCs must be certified every three years.  Cabinets are labeled to indicate that they either were certified on a given date or that the equipment must not be used with infectious materials.

A BSC cannot be moved or disassembled without prior approval from OBS or EH&S – BSC Program. All BSCs must be either surface or gas decontaminated prior to being moved. A risk assessment performed by OBS will determine the type of decontamination is needed prior to the move. After being moved, all BSCs must be re-certified through the EH&S – BSC Program or through an EH&S approved vendor.
