A Biosafety Cabinet (BSC) is an engineering measure designed to shield lab personnel, the surrounding area, and work items from contact with infectious or biohazardous aerosols and splashes. When handling infectious agent-containing materials including initial cultures, stocks, and diagnostic specimens, aerosols and splashes of this nature may be produced.
The three States of Protection
ü Personal defense against dangerous substances within the cabinet
ü To prevent sample contamination, and use product protection.
ü Environmental protection against the cabinet's internal pollutants.
Based on its ability to confine biological agents when handling them, biological safety cabinets are divided into three types.
Class I Biological safety cabinet
As unsterile room air is pulled over the work surface, the Class I BSC is the first and most basic biological safety cabinet (BSC) that protects people and the environment but not the creation of products. Work with biological material in Risk Groups 1, 2, and 3 (RG1, RG2, and RG3, respectively) is appropriate for Class I BSCs.
How it works?
ü Provides you with personnel, product and environment protection
ü It is utilized while working with low to moderate risk biological agent
ü Biosafety Levels: 1, 2 and 3
Class II Biological Safety Cabinet (BSC)
It is commonly found in clinical and research laboratories working with infectious agents in Risk Groups 2, 3, and 4 (if positive-pressure suits are used) or with tissue culture.
How it works?
ü Provides you with personnel, product and environment protection
ü It is utilized while working with low to moderate risk biological agent
ü Biosafety Levels: 1, 2 and 3
Class III Biological Safety Cabinet (BSC)
Risk Group 4 agents employ Class III BSC, which offers the maximum level of personnel safety. It is acceptable for use in laboratories with Biosafety Levels 3 and 4.
How it works?
The maximum level of protection for the environment, the product, and the user is provided by a Class 3 cabinet, which offers the same protection as a Class 2 but is made for working with highly contagious substances classified as Biosafety Level 4.
It is mostly used when handling biological substances that carry an extremely high risk of harm.
To guarantee that no particles may seep out into the space, this sort of cabinet is completely sealed and pressure tested. Two HEPA filters separate the exhaust air from the supply air before it is released into the environment. The operator uses thick rubber gloves that are a component of the Biosafety Cabinet to reach the work area. The work surface may be extended by connecting several glove boxes together.
