Biological Safety Cabinet Certification Policy

Biological Safety Cabinet (Class II) Certification Policy Duke University

Class II Biological Safety Cabinets (BSCs) must be certified:

• When it is initially installed
• Annually thereafter
• When the HEPA or ULPA filter is replaced
• When maintenance repairs are made to internal parts
• When the cabinet is relocated, even if it is within the laboratory

A gas decontamination of the BSC shall be performed prior to certification if the cabinet is used for work with an agent capable of being spread via the airborne route (e.g., Mycobacterium tuberculosis). For all other agents, the BSC must be surface decontaminated with an appropriate disinfectant and adequate contact time prior to any service or certification being conducted on it. The Equipment Statement of Hazard Assessment found at this link must be posted after the decontamination is completed.  

Please contact your lab manager, department business manager or Duke Procurement and Supply Chain Management for an appropriate vendor to certify the BSC following all the Duke requirements.

If there are any questions regarding BSCs, contact the OESO Biological Safety Division (919-684-8822) for more information.
