Biological Safety Cabinets and Their Classifications

Biological Safety Cabinet

A crucial piece of safety equipment could be the Biological Safety Cabinet (BSCs) in which manipulations of infectious microorganisms are performed. Biological safety cabinets are the primary implies of containment developed for working safely with infectious microorganisms. Horizontal clean benches that direct towards the operator usually are not biological safety cabinets and need to not be used for handling infectious, toxic or sensitizing components. BSCs are designed to supply each a clean work atmosphere and protection for employees who work with biological hazards for that reason biosafety cabinet’s uses vertical laminar airflow to create a barrier to airborne particles, such as microorganisms as vertical laminar air flow supplies protection for each the personnel and the product.

Biosafety cabinets make use of the HEPA filtered air for the recirculation more than the work region. The HEPA filter removes airborne particles from the air, but will not get rid of chemical fumes; consequently Biosafety cabinets should really not be confused with the fume hood. Biosafety cabinets are usually not the Fume Hood. Biosafety cabinets are equipped with Ultraviolet lamp that offers protection against contamination, but as the UV light can’t penetrate the dust particles, consequently an additional chemical disinfectant, iodophor need to be use for the cleaning and decontaminating the work location.

Use of biosafety cabinets is suggested for the manipulations of pathogens or antineoplastics that could generate aerosols and for each of the airborne transmitted pathogens (such as Brucella abortus, Mycobacterium tuberculosis, etc).

You will discover three classes of biological safety cabinets;

BSCs Class I: an open-front damaging pressure cabinet. The exhaust air in the cabinet is filtered by a HEPA filter. This class provides personnel and environmental protection, but not product protection.

BSCs Class II: is an open-front, ventilated cabinet. This cabinet delivers a HEPA-filtered, recirculated mass airflow within the work space. The exhaust air in the cabinet can also be filtered by HEPA filters. This class offers personnel, environment and product protection.

BSCs Class III: is a totally enclosed ventilated cabinet of gas-tight building. Operations within the Class III cabinet are carried out by means of attached rubber gloves. When in use, the Class III cabinet is maintained through adverse air pressure of at least 0.5 inches water gauge. Provide air is drawn into the cabinet via HEPA filters. The cabinet exhaust air is filtered by two HEPA filters, installed in series, ahead of discharge outdoors on the facility. The exhaust fan for the Class III cabinet is usually separate from the exhaust fans of your facility’s ventilation system.
