Bio Safety Cabinet

#Biosafety Cabinet:-

1.0 INTRODUCTION

The primary purpose of a BSC is to serve as a means to protect the laboratory worker and the surrounding environment from pathogens. All exhaust air is HEPA-filtered as it exits the biosafety cabinet, removing harmful bacteria and viruses.

A Bio-safety cabinet is called by several names in research industry; microbiological safety cabinet, biological safety cabinet (Acronym: BSC) and Bio-safety hood are such common names which are referred by microbiologists.

Bio-safety cabinets are designed to provide personnel, environmental and product protection. Air flow is drawn around the operator into the front grille of the cabinet which provides personnel protection.

1.1 Types of Class II Biosafety Cabinet:

All Class II cabinets are designed for work involving microorganisms assigned to bio-safety levels 1, 2 and 3.
In order to meet varying research and clinical needs, 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.

Bio-safety Cabinet Class 2 Type A2
In this type of Class II BSC, approximately 70% of the HEPA filtered air is 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 is re-circulated inside workspace through HEPA filter.
Bio-safety Cabinet Class 2 Type B2:
It is total exhaust type BSC, no re-circulation inside workspace; blower exhausts 100% of the filtered air.

Bio Safety Cabinet also known as biology safety cabinets, are enclosed, ventilated laboratory workspace areas designed to protect the user and surrounding environment from pathogens. All exhaust air is HEPA filtered to remove hazardous agents such as virus and bacteria. Bio safety cabinet are used in many laboratories including clinical and research labs.

Classification:
Class 1:

Protection for the user and surrounding environment, but no protection for the sample being tested.

Class 2:

Protection for the user, environment and sample.
Type A1/A2-re-circulate air back into the laboratory. A1 & A2 are similar but different by the minimum average inflow velocity(FPM).
Type B1/B2-re-circulate a percentage of air into laboratory. B2 cabinates are entirely hard ducted.

Class 3:

Also known as glove boxes, provides maximum protection: the enclosure is gas-tight, and all materials enter and leave through a dunk tank or double-door autoclave.

Choice of cabinet depends on level of protection needed for the laboratory worker and the sample of interest.

Other Details:
