Biological Safety Cabinets and Their Classifications
An important piece of safety equipment would be the Biological Safety Cabinet (BSCs) in which manipulations of infectious microorganisms are performed. Biological safety cabinets will be the primary implies of containment created for operating safely with infectious microorganisms. Horizontal clean benches that direct towards the operator are not biological safety cabinets and will have to not be used for handling infectious, toxic or sensitizing supplies. BSCs are created to provide each a clean work environment and protection for employees who work with biological hazards therefore biosafety cabinet’s uses vertical laminar airflow to create a barrier to airborne particles, including microorganisms as vertical laminar air flow provides protection for both the personnel and the product.

Biosafety cabinets make use of the HEPA filtered air for the recirculation over the work area. The HEPA filter removes airborne particles from the air, but will not remove chemical fumes; thus Biosafety cabinets must not be confused with all the fume hood. Biosafety cabinets aren’t the Fume Hood. Biosafety cabinets are equipped with Ultraviolet lamp that offers protection against contamination, but because the UV light can’t penetrate the dust particles, for that reason another chemical disinfectant, iodophor need to be use for the cleaning and decontaminating the work area.
Use of biosafety cabinets is suggested for the manipulations of pathogens or antineoplastics that may create aerosols and for all of the airborne transmitted pathogens (for instance Brucella abortus, Mycobacterium tuberculosis, and so forth).
You’ll find 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 gives personnel and environmental protection, but not product protection.
BSCs Class II: is definitely an open-front, ventilated cabinet. This cabinet supplies a HEPA-filtered, recirculated mass airflow inside the work space. The exhaust air from the cabinet is also filtered by HEPA filters. This class delivers personnel, atmosphere and product protection.
BSCs Class III: is really a totally enclosed ventilated cabinet of gas-tight building. Operations within the Class III cabinet are performed by means of attached rubber gloves. When in use, the Class III cabinet is maintained by means of damaging air pressure of a minimum of 0.5 inches water gauge. Supply air is drawn into the cabinet by means of HEPA filters. The cabinet exhaust air is filtered by two HEPA filters, installed in series, before discharge outside on the facility. The exhaust fan for the Class III cabinet is typically separate from the exhaust fans of the facility’s ventilation system.
