Biological Safety Cabinet Usage, Training and Certification


Biological Safety Cabinets (BSC) are an essential piece of laboratory safety equipment. They are engineered enclosures designed to contain biohazardous materials. There many types of biological safety cabinets that provide a range of protection and control. The most common unit on campus is the Class 2A cabinet. Class 2A cabinets provide protection to the researcher, a contaminant free work surface, and protect the environment from hazardous bio aerosols that may be exhausted. Researchers handling biohazardous material that poses a risk to human health and with the potential for exposure via inhalation must use a BSC.

Any researcher working in a Biological Safety Cabinet must complete the required training course located on Blackboard.  Also, the Institutional Animal Care and Use Committee (IACUC) now is requiring that anyone working with animals in the Lab Animal Care Unit (LACU) must complete the Biological Safety Cabinet training course as well.  This training must be completed every 12 months.

To ensure that a BSC performs in a manner that provides the necessary protection its performance must periodically be validated. This is done through a certification process performed in accordance with the method established in NSF/ANSI 49 – the Standard for the Field Certification of Biosafety Cabinetry.

BSCs must be re-certified at least:

  • Annually
  • After BSC maintenance or filter changes
  • After moving a BSC to a new building or room

To have your Biological Safety Cabinet certified or re-certified you can email bsc@uthsc.edu to schedule the certification.
