What should a standards Biosafety Cabinet assure?


The risk of contracting diseases among lab workers is quite high as they deal with biologically hazardous infections causing viruses and bacteria. The risk of disease is 8,000 times higher in lab technicians, especially when dealing with highly sensitive communicable diseases. It is imperative to provide a safe working enclosed cabinet where they can work with safety. The Biosafety Cabinet serve this purpose and safeguard the technician from exposure to harmful and disease-causing microorganisms.

Guarding lab workers against biohazardous particles, labs dealing with such materials must have a biosafety cabinet installed in their laboratory immediately if they already do not have one. While working on highly transmissible particles they should wear proper PPE (personal protective equipment) for no exposure to these particles.

What are the three classes of BSC?

BSC come in three classes, Class I, Class II and Class III cabinets. All three perform a common function of protecting the sample enclosed within the cabinet. Let us understand each’s function in detail.

Class I

This BSC features a sash which is the window and the only connection that the investigator has with the samples inside the cabinet. As soon as the sash is parted an inward surge of air blows into the cabinet to prevent aerosol movement of the particles outside through negative pressure. This air movement protects the person and the surrounding environment of the lab. However, the sample inside the cabinet may be contaminated by the inward unfiltered air circulation. 

Class II 

This cabinet solves the problem faced by the first cabinet. Through a double directional airflow, it creates an air barrier between the lab and the sample. The shield prevents the outside air to reach the sample. The air maintains a downward flow within the cabinet from the drawn-in air which is sucked by the HEPS filters. This cabinet is further classified in type A1, A2, B1 or B2 cabinets depending on their air circulation systems, and air exhaust designs.

It should be noted that both Class I and II are prone to disruption and should be placed close to open windows and in secluded lab areas.

Class III 

This is a fully closed cabinet with only glove port inlets. The ports allow work inside the cabinet. An interlocking door at the side of the work area allows the transfer of materials. The air streaming works just like the class II cabinet system protecting the aerosol transfer of transmissible microorganisms, the air is efficiently exhausted by the HEPA filters.
