A Biological Safety Cabinet (BSC), also known as a Biosafety Cabinet is mainly used for handling pathogenic biological samples or for applications that require a sterile work zone. A biological safety cabinet creates inflow and downflow of air that provides operator protection. The downflow air passes through an ULPA/HEPA filter and creates an ISO Class 3 work zone to protect samples from the risk of cross-contamination. The air exhausted also passes through an ULPA/HEPA filter prior to release to protect the environment.

Class 1 Biological Safety Cabinets
The Class 1 biological safety cabinet provides personnel and environment protection for the safe handling when working with chemicals and powders.
The air enters the cabinet via the front aperture passing through a built-in exhaust fan, HEPA and/or Carbon filter, thus providing operator and environmental protection. The air then exits the cabinet at the rear of the work surface. The escape of any airborne particulates generated within the cabinet are therefore controlled by means of the inward airflow through the front aperture and by filtration/absorption of the exhausted air.
Unlike fume hoods, the HEPA filter in the cabinet protects the environment by filtering the air before it is exhausted.
A Class 1 Safety Cabinet is not appropriate for handling research materials that are vulnerable to airborne contamination, since the inward flow of unfiltered air from the laboratory can carry microbial contaminants into the cabinet. In these circumstances a Biological Safety Cabinet Class II is more applicable.
Class 2 Biological Safety Cabinets
The Class 2 Biological Safety cabinet must meet the requirements for personnel, environmental and product protection. The air-flow is drawn into the work chamber via the front aperture and continues under the worktop and goes up the back plenum, where 70 % is being recirculated through the main HEPA filter to provide down flow and 30 % exits out through the HEPA filter to exhaust. The vertical laminar flow Biological Safety Cabinet provides operator protection by means of inflow, product protection by means of down flow and environmental protection by means of the filtered exhaust.
The Biological Safety Cabinet is equipped with dual HEPA filters according to the European standard EN 12469 and can be certified as per the standard by TüV. It can also be manufactured with triple filters according to DIN 12980. The triple HEPA filter system ensures the elimination of any possible cross contamination, as the air in the work chamber has to pass through two sets of main HEPA filters. This makes the triple filter cabinet the ideal choice of cabinet for working with hazardous materials such as cytostatics, virus manipulation and category 3 pathogens. The triple filter Biological Safety Cabinet is easier to service as no prior decontamination is needed.
There are two different types (Type A and Type B) based on their construction and configuration.
They are classified according to the percentage of air exhausted to that of air recirculated from the common air plenum. In addition, the cabinets have different means of exhaust, where some may exhaust air directly back into the laboratory, whilst others may exhaust air via ductwork to an external ventilation system.
Type A cabinets are suitable for microbiological research with the absence of any volatile or toxic chemicals since air is recirculated within the cabinet. This cabinet type is further sub-typed into types A1 and A2.
Type B cabinets are hard-ducted to the building exhaust system and incorporate a negative pressure plenum, and are further sub-typed into types B1 and B2.
Class 3 Biological Safety Cabinets
A Class 3 Biological Safety Cabinet is an aerosol-tight enclosure with a non-opening, completely sealed, front window, so the operator is separated from their work by a physical barrier. The cabinet is also referred to as a ' Glovebox'. Work is conducted via long heavy-duty rubber gloves attached to the ports in the front of the safety cabinet in a gas-tight manner. This allows access and work to be performed on your product within the cabinet without compromising containment.
Removal of materials from the cabinet must be through a safety airlock transfer hatch or double door autoclave, which is located on the side of the chamber of the BSC for decontamination. Interlock or protocols must be used for the autoclave and pass-through doors to prevent both doors from being open at the same time.
The cabinet is designed for work with high risk biological agents in Biosafety Level 4 laboratories, where maximum containment and protection are required. Examples include Ebola, the Lassa virus and any agent with unknown risks of pathogenicity and/or transmission. When the Biological Safety Cabinet Class III is installed in a Biosafety Level 4 Laboratory or facility, it offers an additional level of containment and safety for high risk working procedures.
How does a biological safety cabinet work?
A Biological Safety Cabinet is a ventilated enclosure offering protection to the user, the product and the environment from aerosols arising from the handling of potentially hazardous micro-organisms. The continuous airflow is discharged to the atmosphere via a HEPA filter.
The three States of Protection
Personal Protection from harmful agents within the cabinet
Product Protection to avoid contamination of the samples.
Environmental Protection from contaminants contained within the cabinet.
Biological Safety Cabinets are classified into three classes based upon their containment capabilities when working with biological agents.
Class 1 Cabinets
Provides personal and environment protection.
Used when working with low to moderate risk biological agents.
Biosafety levels: 1, 2 and 3
Class 2 Cabinets
Provides personnel, environment and product protection.
Used when working with low to moderate risk biological agents.
Biosafety Levels: 1, 2 and 3
Class 3 Cabinets
A highly specialized laboratory "glovebox". A Class 3 cabinet provides the same protection as a Class 2 but is designed for working with Biosafety Level 4 highly infectious agents and provides the highest level of protection for the environment, product and user.
Used when you are working with very high risk biological agents.
Biosafety Level: 4
Biosafety Level 1 applies when working with biological agents, which pose a minimal risk/ threat to laboratory personnel and the environment. Work with these types of agents are generally performed in open laboratory cabinets without the use of special containment equipment.
Biosafety Level 2 covers working with pathogenic or infectious organisms posing a moderate hazard.
Examples include Salmonellae, Hepatitis B virus and Measles virus.
Biosafety Level 3 applies when working with indigenous or exotic agents, which may cause serious or lethal disease via aerosol transmission. Examples include Yellow Fever and Encephalitis.
In Biosafety Level 4, applies when working with extremely dangerous, contagious and life-threatening agents. Maximum containment and protection is required at all times. Examples include Ebola, the Lassa virus and any sample with unknown risks of pathogenicity and transmission.
