Tufts University Decontamination of Biological Safety Cabinets

Decontamination of Biological Safety Cabinets for Tufts University

There are three classes of biological safety cabinets: Class I, II and III. A Class I cabinet protects the operator and the environment while a Class II cabinet additionally protects the materials in the cabinet from laboratory air contamination because all of the air in the cabinet is sterile having passed through a HEPA (high efficiency particulate air/absolute) filter. A Class III cabinet is glove box that is entirely enclosed with all manipulations inside the cabinet performed using gas tight gloves affixed to the front of the cabinet.
