What is the Safety Cabinet Class 2?

A Safety Cabinet Class 2, also known as biological safety cabinet is a closed, negative-pressure ventilated work area that uses HEPA filters to remove fine particles from the air.

It is used in laboratories that operate with biologically hazardous compounds to guard against aerosols and contamination of the workers, the surroundings, and, depending on the kind, the items in the cabinet.

Two air streams separate this cabinet from the lab, forming a barrier. The first one pours out of the lab and into its front grille, protecting workers.

The second one is the downward stream which comes from air that has been sucked into and passed through the HEPA filters.

It prevents contamination of the samples in the cabinet by continually cleaning this product inside from aerosols.

Potentially polluted air is either recirculated or driven out from the building by both air streams, depending on where it is coming from.

Type A1, A2, B1, or B2 divisions are characterized based on whether or not they recycle air, how often, and also upon the architecture of its exhaust system.

What is the Difference Between the Safety Cabinet Class 2 and a Chemical Fume Hood?

Science-related risks may be contained in both these products, however; these vary in terms of protection, airflow, and appropriate uses.

Protecting lab workers from exposure to hazardous chemicals is the sole purpose of using fume hoods, which are ventilated enclosures.

HEPA filters and directed airflow are used in life science enclosures to safeguard the environment, workers, and products. Both these products can recirculate or expel filtered air, based on the process in which you are working.

A Safety Cabinet Class 2 is only appropriate for working with hazardous particles like bacteria, viruses, and hazardous pharmaceuticals.

Airflow in Fume Hood

Fume hoods suck air around the operator towards the top of the device because they are used to contain potentially harmful chemicals and materials.

The air moves over the surface of the work surface as it passes through the aperture. Before being discharged into the atmosphere, it must first pass through a series of ducts.

Airflow in the Safety Cabinet Class 2

The operator is shielded from hazardous air, sterile air flows downwards into the work area, and exhaust air is HEPA-filtered until it is ultimately returned to the laboratory or discharged into the atmosphere.

Applications of Fume Hood

It is possible to utilize a chemical fume hood to deal with:

• Chemical Odors
• Toxic Gases
• Reactive Materials
• Spattering Chemicals
• Carcinogens
• Flammables
• Other Poisonous and Volatile Substances

Applications of Safety Cabinet Class 2

The class ii biosafety cabinet provides a sterile atmosphere conducive to research involving pathogenic microbes or other potentially dangerous particles.

It has also subcategories that are classified on the basis of the level of containment it offers, and the degree of protection it can provide.

Variations in Fume Hood

Chemical fume hoods with a consistent air volume are the most popular variety.

By-pass chemical fume hoods include auxiliary air, decreased air volume, and excellent performance fume hoods.

High-performance hoods with a variable air volume (VAV) system are by far the most power-efficient type of these hoods. Hoods are also available for special occasions. For example, those designed specifically to manage perchloric acid and manufactured of acid-resistant materials.

Additionally, for radioactive purposes, hoods have enhanced decontamination functions that frequently require ducting filters. It is your choice to go for the ducted or ductless fume hood, as per your requirement.

Variations in the Safety Cabinet Class 2

Class II BSCs are divided into three primary categories: Type A, Type B, and Type C. These are encased in a canopy and connected to the outside.

Safety Cabinet Class 2, Type A1, and Type A2 are much similar; however, they differ in that they need a different inward average air velocity. Class 2 Type A is unable to perform work involving radionuclides and hazardous chemicals.

Dedicated exhaust systems are used with Safety Cabinet Class 2 Type B2. Microbiological experiments in the BSC may require the use of hazardous chemicals, so choose a cabinet that is compatible with this application.

The Type B1 cabinet recirculates some air back into the lab, whereas the Safety Cabinet Class 2 Type B2 exhausts all of the air out of the room.

When working with hazardous chemicals, Type C1 can be installed either ducted or non-ducted, depending on the application.

Recirculation is used in the BSC’s peripheral sections to supply fresh air to the work area. Due to this, the energy consumption is reduced as well as enhanced containment is provided.
