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.

Call 262-1809 or email for service requests relating to: biological safety cabinets, animal and waste transfer stations, biohazard containment systems, clean benches, gas decontamination, and HEPA vacuum and filtration systems.

Certification, Maintenance, & Service

Use the following form to request certification, maintenance or service:

Biological Safety Cabinets (BSCs) must be certified when initially purchased and installed. Annual certification is required for BSCs used for work that has been determined to be BSL-2 or higher, unless it is waived by OBS, which is considered on a case-by-case basis for low-risk activities. BSCs used for BSL-1 work only are not required by the IBC to be annually certified (December 2010 vote). 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. [Adopted by the IBC, January 1993].


Please refer to Table 3 of the UW-Madison Researchers' Biosafety Manual.
