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

Biosafety cabinets make use of the HEPA filtered air for the recirculation more than the work location. The HEPA filter removes airborne particles in the air, but will not get rid of chemical fumes; for that reason Biosafety cabinets should really not be confused together with the fume hood. Biosafety cabinets aren’t the Fume Hood. Biosafety cabinets are equipped with Ultraviolet lamp that supplies protection against contamination, but as the UV light cannot penetrate the dust particles, hence one more chemical disinfectant, iodophor really should be use for the cleaning and decontaminating the work area.
Use of biosafety cabinets is encouraged for the manipulations of pathogens or antineoplastics that could make aerosols and for all the airborne transmitted pathogens (for instance Brucella abortus, Mycobacterium tuberculosis, and so forth).
You will discover 3 classes of biological safety cabinets;
BSCs Class I: an open-front negative pressure cabinet. The exhaust air in the cabinet is filtered by a HEPA filter. This class supplies personnel and environmental protection, but not product protection.
BSCs Class II: is definitely an open-front, ventilated cabinet. This cabinet delivers a HEPA-filtered, recirculated mass airflow inside the work space. The exhaust air from the cabinet can also be filtered by HEPA filters. This class gives personnel, environment and product protection.
BSCs Class III: is really a entirely enclosed ventilated cabinet of gas-tight construction. Operations within the Class III cabinet are conducted by way of attached rubber gloves. When in use, the Class III cabinet is maintained via negative air pressure of a minimum of 0.5 inches water gauge. Supply air is drawn into the cabinet via HEPA filters. The cabinet exhaust air is filtered by two HEPA filters, installed in series, prior to discharge outdoors with the facility. The exhaust fan for the Class III cabinet is normally separate in the exhaust fans with the facility’s ventilation system.
