Biosafety cabinets are used as the primary means of containment for working safely with infectious microorganisms. However, biosafety cabinets are only one part of an overall biosafety program, which requires consistent use of good microbiological practices.
Biosafety cabinets are used as the primary means of containment for working safely with infectious micro organisms.However biosafety cabinets are only one part of an overall biosafety program, which requires consistent use of good micro biological practices. Biosafety cabinets are designed to prevent biological exposure to personnel and the environment and may also protect experimental material from being contaminated when appropriate practices and procedures are followed. Three kinds of biosafety cabinets, designated as Class I, II and III have been developed to meet varying research and clinical needs Biological safety cabinets use high efficiency particulate air (HEPA) filters in their exhaust and/or supply systems. These filtered cabinets are primarily designed to protect against exposure to particulates, including biological agents used in the cabinet. Protection against exposure from fumes generated by radionuclides and toxic chemicals is only provided by Class II, Type B biosafety cabinets, which are ducted directly to the facility exhaust.
