SB BIO SAFETY CLASS II
Class 2 Biosafety Cabinets are designed to provide protection to operator, environment and materials inside the workspace. These Class II BSCs are utilized for containing low-to-moderate risk biohazardous materials. These cabinets have downward airflow and HEPA filters that re-circulate air providing required level of protection from microorganisms and aerosols. these cabinets are extensively used in drug preparation, chemotherapy preparation, clinical research, medical and pharmaceutical sectors, life science and industrial laboratories etc. it must follow relevant application specific standards.
Different Names Same Purpose
A Biosafety cabinet known by several names in research industry; microbiological safety cabinet, biological safety cabinet (Acronym: BSC) and Biosafety hood are such common names which are referred by microbiologists.
Types of Class 2 Biosafety Cabinet
In order to meet varying research and clinical needs, Class II Biosafety Cabinets are designed mostly in 3 types i.e. Type A2, Type B1, and Type B2. Regardless of type, each cabinet provides the same level of protection. According to international sanitation standards, there are exactly same pass and fail criteria for all of them.
Now how do we differentiate each Class 2 Biosafety Cabinet? Each cabinet is differentiated by a number of factors some of them are amount of air re-circulation, air ventilation and negative and positive pressure. Before buying a cabinet a user must know the basic differences between these 3 types of Biosafety cabinets which are explains below:
Biosafety Cabinet Class 2 Type A2:
this type of Class II BSC, approximately 70% of the HEPA filtered air circulated through the cabinet, while 30% passes through an exhaust HEPA filter and is discharged.
Biosafety Cabinet Class 2 Type B1:
This Class II BSC, exhausts 60% – 70% of the HEPA filtered air, while 30% – 40% air re-circulated inside workspace through HEPA filter.
Biosafety Cabinet Class 2 Type B2:
It is total exhaust type BSC, no re-circulation inside workspace; blower exhausts 100% of the filtered air.
Biosafety Cabinet Maintenance
In order to take optimum use of a Biosafety cabinet and maintain operational integrity, proper maintenance is essential. A Biosafety operator must follow routine cleaning and inspection schedule. chemicals extensively used in BSC cabinets, filter saturation should be checked regularly, if need replace it immediately. Other minor check-ups must be done on regular basis such as air flow, surface cleaning, motor, and lighting and electrical switches etc.
