What are the Major Parts of a Biohazard Safety Cabinet?
A Biohazard Safety Cabinet is composed of various functional units that come together to make one system.
If there is any fault in one of the components, the efficiency of the system is greatly compromised thus producing a direct impact on the protection of the people working and the environment.
Its major components are as follows:
Front Access Opening
It is for the maintenance of inward flow which must be maintained for the continuous working of the system.
HEPA filter or ULPA filter allowing unidirectional flow in the area and avoiding turbulence addition of a prefilter can enhance the efficiency as it takes most of the larger particles and increases the lifespan of the main filter.
An exhaust system consisting of fans and air handling units deals with the air currents leaving the area.
This air must be cleaned before leaving so that there are no harmful contaminants in the environment.

What are the Different Classes of a Biohazard Safety Cabinet?
The biosafety in microbiological and biomedical laboratories manual has classified the Biohazard Safety Cabinet into three classes.
This manual is produced by the National Institute of Health and US Centres for Disease Control.
Class 1 Biohazard Safety Cabinet
Though class 1 provides environmental and personal protection it does not guarantee the protection of the product.
The air movement in this type is the same as that of the chemical fume hood. It comes with an air exiting system and HEPA filter.
Class 2 Biohazard Safety Cabinet
When dealing with low-risk materials or moderate-risk materials, class 2 is mostly preferred.
It provides personal, product, and environmental protection but it cannot deal with high-risk contaminants.
Being extensively used in industries, pharmacies, and research laboratories, it is greatly responsible for the removal of harmful microorganisms and chemical contaminants.
Biosafety cabinet class 2 comes with a HEPA filtration system that is capable of preventing cross-contamination. The air is drawn from the front grille and it enters in a downward flow. The existing air is also filtered for the protection of the environment.
Class 2 is further classified into types A1, A2, B1, and B2.
Class 3 Biohazard Safety Cabinet
This class deals with highly dangerous operations and infectious microbiological agents that can cause serious diseases.
These contaminants are dangerous for the environment, the personnel working in that place and the products being dealt with.
As it is for high-risk areas, biological safety cabinet class 3 is a gastight enclosed space with closely administered entries and exits.
The HEPA filter works in combination with an incinerator to allow maximum removal of the impurities. Several units can be joined together to increase their efficiency.
Biohazard Safety Cabinet Class 2
Why Do you Need a Biohazard Safety Cabinet for your Applications?
Biohazard refers to any biological material or substance that can cause damage to a human or environment.
It can lead to serious infectious diseases that can be either transmissible or non-transmissible. Biohazard material includes pathological waste, human waste, bacterial culture, vials containing different pathogens.
When working in a pharmaceutical clean room, a medical clean room, or a hospital, a person is more likely to catch a disease due to biohazard contamination.
Therefore it is necessary that the air does not contain any disease-causing microorganisms or a dangerous chemical that has a deteriorating effect on human health.
These contaminants not only harm human health but also affect the results of the reactions and working of an application. Also, when these contaminants are released into the environment, this unclean air can cause health problems for plants, animals, and humans.
When a contaminant enters the environment, it becomes difficult to control and can lead to disastrous effects.

What is the Working Principle of the Biohazard Safety Cabinet?
A Biohazard Safety Cabinet works by removing the aerosol contaminants from the air. It is done by using a HEPA or ULPA filtration system based on the following factors:
- Size of the Facility
- Decontamination Needs of the Area
- Type of Procedure
- Particulate Size
- Number of Particles in the Air
- Air Patterns
The contaminated air is fed into the front sash and it is allowed to flow through the system in such a way that it passes through the filter.
The efficiency of the filter is enhanced by using a primary filter before the main filter. This helps to decrease the contamination load and give better performance.
Then the filtered air is recirculated into the area where the cabinet is installed. In this way, the air currents entering the cabinet go through the system as the airflow patterns change and come out clean.
If the air is to be circulated back into the environment, it is free of any contaminants after passing through the filter and therefore is safe for the environment.
As there is no contamination in the air inside the room, the products, and the items associated with the procedure being carried out are also safe.
The person working in a lab is already wearing the protective equipment but there is still a chance of catching infections when working in an application that requires level 3 and level 4 safety.
Therefore, a Biohazard Safety Cabinet keeps the area ventilated and clean.
