Cabinet Purpose :

In varying degrees, a laminar flow biological safety cabinet is designed to provide three basic types of protection:

• Personnel protection from harmful agents inside the cabinet.

• Product protection to avoid contamination of the work, experiment, or process.

• Environmental protection from contaminants contained within the cabinet.

How Biological Safety Cabinets Are Classified ?

Classification is an important consideration in the selection of any biological safety cabinet. Over the years, the scientific community has adopted commonly accepted classification criteria to differentiate containment capabilities and performance attributes. Biological safety cabinets are divided into three classifications.

Class I - Personnel and Environmental Protection Only

The Class I biological safety cabinet is designed to provide personnel and environmental protection only.

• A Class I cabinet does not protect the product from contamination because dirty room air constantly enters the cabinet front to flow across the work surface.

• As a partial containment unit, the Class I cabinet is suitable for work involving low to moderate risk agents (biosafety levels 1,2 and 3) where there is a need for containment, but not for product protection.

• Unlike conventional fume hoods, the HEPA filter in the Class I cabinet protects the environment by filtering air before it is exhausted.

• Personnel protection is made possible by constant movement of air into the cabinet and away from the user.

Class II - Product, Personnel and Environmental Protection

A Class II cabinet must meet requirements for the protection of product, personnel and the environment. This type of cabinet is widely used in clinical, hospital, life science, research and pharmaceutical laboratories.
In general, cabinets are classified according to the method by which air volumes are recirculated or exhausted.
The Class II biological safety cabinet has three key features-

• A front access opening with carefully maintained inward airflow.

• HEPA-filtered, vertical, unidirectional airflow within the work area.

• HEPA-filtered exhaust air to the room or exhaust to a facility exhaust system.

Vertical, unidirectional airflow and a front access opening are common to most Class II cabinets. But, because Class II designs permit different airflow patterns, velocities, HEPA air filter position, ventilation rates and exhaust methods.

Classification : Cabinets previously classified as Class II, Type A/B3 are now classified as Class II, Type A2. These biosafety cabinets may be exhausted to the room, or connected to a facility exhaust system via a "canopy" connection (NSF recommends a canopy connection for cabinets exhausted to the outdoors). The Class II, Type B3 classification no longer exists for new units.
It is important to understand differences in cabinet Type in order to select the proper cabinet for your application.

Note :  All Madhav biological safety cabinets provide containment and protection from airborne particulates for personnel, the work area, and the environment. Depending on the Type and nature of the exhaust configuration, and whether the exhaust system is treated or untreated, this containment and protection can extend to vapors and gases as well.

Class III Total Containment Cabinets :

Class III biological safety cabinets are gas-tight, designed for use with high risk biological agents. Class III cabinets provide the highest level of personnel, product and environmental protection. Because of the sensitive nature of most procedures performed within a Class III cabinet, Madhav builds each BSC system to exact customer specifications.
Typical applications include :

• Working with emerging diseases or diseases marked for near eradication.

• Weighing and diluting chemical carcinogens.

• Working with high concentrations of low to moderate risk agents.

• Working with large amounts of low to moderate risk agents.

• Use of equipment or instrumentation generating high aerosol volumes.

• Maximum containment of highly infectious or hazardous experimental materials.

• An extra level of safety not available in Class I or II cabinets.
