Biological Safety Cabinets and Laminar Flow Cabinets

Biological Safety Cabinet (BSC) is a ventilated cabinet that uses a combination of High-Efficiency Particulate Air (HEPA) filtration, laminar airflow, and containment to provide personnel, product, and environmental protection from biohazardous agents. This is achieved by air intake and recirculation that is filtered prior to exhausting to the cabinet exterior. All work with potentially infectious agents should be completed inside of a biological safety cabinet.

In addition to ensuring safe BSC practices within laboratories, Auburn University Risk Management and Safety coordinates the certification, relocation, decontamination, and disposal of all biological safety cabinets and laminar flow cabinets on campus.

Certification for BSCs and LFCs

All biological safety cabinets are required to have an annual inspection and certification if used for primary containment and personal protection against biohazards. This annual inspection assures proper cabinet operation and capability in accordance with the manufacturer’s specifications and/or the National Sanitation Foundation (NSF) 49 Standard. It is also recommended that all laminar flow cabinets or “clean benches” be certified annually to assure product protection capability.

Risk Management and Safety coordinates with a preferred vendor (Safety Plus, LLC) twice a year to certify all the cabinets on campus, as well as any time in between for decontamination and recertification needs. All certification costs are the responsibility of the requesting department and payment processing is managed by RMS.

All cabinets must be certified when installed, relocated, or upon completion of major repairs.

If your cabinet is in need of certification, please contact Jessica Powell (334-707-2835 or
