The Vital Role of Biological Safety Cabinets

Biological safety cabinets (BSCs) play a pivotal role in laboratories across the globe, safeguarding both researchers and the environment from potentially hazardous materials. Global Lab Supply is your trusted partner in procuring top-quality BSCs to ensure your lab's safety and compliance.

Understanding Biological Safety Cabinets

Biological Safety Cabinets, commonly referred to as BSCs, are a cornerstone of laboratory safety. These specially designed enclosures are engineered to protect researchers, samples, and the environment from a variety of biological and chemical hazards, making them indispensable in research, diagnostic, and healthcare facilities.

Types of Biological Safety Cabinets

There are three primary types of BSCs, each catering to specific needs and applications:

Class I BSCs: These cabinets provide protection for the operator and the environment but not the sample. They are suitable for handling low- to moderate-risk agents.

Class II BSCs: These offer protection to both the operator and the environment, with an added layer of security for the sample. They are widely used in microbiology, clinical, and pharmaceutical labs.

Class III BSCs: The highest level of containment, these cabinets are entirely enclosed and provide maximum protection for both the operator and the sample. They are used for working with high-risk agents, such as those associated with bioterrorism.

Importance of Biological Safety Cabinets

BSCs serve several critical functions in laboratories:

Personnel Protection

The primary function of a BSC is to shield laboratory personnel from exposure to harmful pathogens and chemicals. The airflow within the cabinet ensures that any potentially hazardous substances are contained, preventing them from escaping into the environment.

Sample Protection

Biological safety cabinets also safeguard the integrity of the samples being handled. Contaminants are prevented from infiltrating the sample, ensuring that research results are accurate and reliable.

Environmental Protection

Beyond safeguarding individuals and samples, BSCs contribute to overall environmental safety. By preventing the release of hazardous materials, these cabinets help maintain the laboratory's clean and safe environment.

Regulatory Compliance

BSCs are essential for compliance with various regulatory standards, including those established by organizations like the Centers for Disease Control and Prevention (CDC) and the National Institutes of Health (NIH). Using BSCs ensures that laboratories meet the necessary safety guidelines.

Selecting the Right Biological Safety Cabinet

Choosing the appropriate BSC for your laboratory requires careful consideration of several factors:

Biosafety Level (BSL)

Determine the BSL of the materials you will be working with. Different BSLs require different levels of containment, and your BSC choice should align with these requirements.

Type and Frequency of Work

Consider the type of work your laboratory conducts and how frequently you'll be using the BSC. High-intensity work may necessitate a more robust BSC.

Space and Layout

Evaluate your lab's space and layout to ensure that the chosen BSC fits comfortably and allows for efficient workflow without compromising safety.

Filtration

BSCs come with various types of filters, such as HEPA and ULPA filters. Ensure that the filtration system meets your specific needs and the regulations you must adhere to.

Manufacturer Reputation

Choose a reputable manufacturer like Global Lab Supply to guarantee the quality and compliance of your BSC. A trusted provider will offer reliable products and excellent customer support.

Proper BSC Operation and Maintenance

Types And Working Mechanism Of Microbiological Safety Cabinets

Microbiological safety cabinet is a designing control planned to ensure laboratory workers, laboratory condition and work materials from introduction to irresistible or biohazardous pressurized aerosol products and splashes. Such aerosol products and sprinkles might be created while controlling materials containing irresistible specialists, for example, essential cultures, stocks, and diagnostic specimens.

There are three sorts of safety cabinets, Classes I, II, and III. Class II and Class III microbiological safety cabinet give personnel, natural just as item security. Though Class I safety cabinet, which is the most essential one, gives personnel and natural assurance as it were. When appropriately utilized Biological safety cabinets have been demonstrated to be exceptionally powerful in diminishing laboratory-procured diseases and cross-contamination of societies.

Class I Microbiological safety cabinet

Class I microbiological safety cabinet is the first planned and basic Biological Safety Cabinet (BSC) which gives staff and ecological security however not item creation (as unsterilized room air is drawn over the work surface). Class I microbiological safety cabinets are appropriate for work with Risk Group 1 (RG1), Risk Group 2 (RG2), and Risk Group 3 (RG3) biological material.

How it works

Room air is attracted through the front opening at least a speed of 0.38 m/s. The front opening additionally permits the administrator's arms to arrive at the work surface inside the cabinet while the person watches the work surface through a glass window. The window can likewise be completely raised to give access to the work surface for cleaning or different purposes.

The directional progression of air whisks vaporized particles that might be created on the work surface away from the laboratory specialist and are then released from the BSC through a HEPA filter.

Class II Microbiological Safety Cabinet

A Class II Microbiological Safety Cabinet is a ventilated cabinet, which gives work force, item, and ecological protection. It is normally found in clinical and research labs working with irresistible operators in Risk Groups 2, 3 and 4 (if positive-pressure suits are utilized) or with tissue culture.

There are four sorts (A1, A2, B1, and B2 ) of Class II microbiological safety cabinets. The fundamental contrasts between the sorts are the proportion of air depleted from the BSC to the air that is recycled inside the BSC and the kind of exhaust framework present.

About 90% of all biosafety cabinets introduced are Type A2 cabinets. There is a restricted requirement for Class II Type B microbiological safety cabinets. What's more, Class II Type B microbiological safety cabinets require the unmistakable establishment and working conditions to work effectively. 

How it works

The working component of Class II microbiological safety cabinets varies as indicated by its sorts. It has an open front with internal airflow for personnel assurance, descending HEPA separated laminar airflow over the work surface for item insurance and HEPA sifted depleted air for environmental security. The room air and recycled air are HEPA sifted before streaming downwards over the work zone. Class II microbiological safety cabinets can be depleted into the regulation zone or straightforwardly to the outside air through a thimble or hard-ducted association relying upon the sorts. The measure of air that recycles or depletes relies upon the sorts.

Class III Microbiological Safety Cabinet

Class III microbiological safety cabinet gives the most elevated level of personnel security and is utilized for Risk Group 4 specialists. It is reasonable for work in Biosafety Level 3 and 4 research centers.

How it works

This kind of cabinet is completely encased and is tried constrained to guarantee that no particles can spill from it into the room. Supply air is HEPA-separated and exhaust air is released to the air through two HEPA channels. The administrator gets to the work surface by methods for heavy-duty rubber gloves which structure some portion of the cabinet. A few glove boxes can be consolidated to expand the work surface. Airflow is kept up by a devoted exhaust framework outside to the cabinet, which holds the cabinet inside under negative pressure.

The Class III microbiological safety cabinets ought to have a joined go through the box that is sterilizable and is outfitted with HEPA-sifted exhaust. The Class III cabinet might be associated with a double door autoclave used to purify all materials entering or leaving the cabinet.

How To Operate Laboratory Fume Hood

A chemical fume hood protects the user while a biosafety cabinet protects the user, the environment and the material. Make sure, fume hoods and biological safety cabinets are not interchangeable because they have different functions and technologies. Basically fume hoods are used to remove chemical fumes away from the work area.

A chemical fume hood protects the user while the biosafety cabinet protects the user, the environment and the material. Biosafety cabinets have the high efficiency particular air filters while chemical fume hoods or not. A chemical fume hood is designed to remove chemical fumes and aerosols from the work area while a biosafety cabinet is designed to provide both the protection for employees as well as for the cleaning purpose. Basically these are the specialized types of laboratory equipments which have some special appeal of its own and now day’s different technologies are coming in the foreign countries which help to do the work much easier and beneficial as well.

Although these the fume hoods should have some safety security purposes for using these two equipments and this is also the operating procedures of fume hoods-

To protect these twos, do not install the fume hood directly opposite to the workstations.
Try to install fume hoods to allow access to their supply and exhaust filters for annual certification testing and HEPA filter changes. The top of the cabinet must be at least 18’ below the ceiling to field test exhaust flow according to NSF standard 49.

To avoid disturbing the airflow that protects the worker, locate fume hoods so lab personnel existing and entering the lab do not pass in front of them.

A laboratory fume hood is a workspace designated for containment of hazardous reagents used in experiments or assays, or toxic fumes that result from reactions or experiments. Found in all types of labs, the primary goal of the hood is to protect the user from these reagents, and to protect other laboratory staff, animals and/or experiments from contamination.

Application will determine the type of fume hood needed, for example specially designed units are designed to protect users from radioisotopes, and units with a wash-down system of water spray nozzles dispersed throughout the hood are required for work with perchloric acid. When choosing an appropriate hood for your lab, consider special application requirements, energy consumption, available space and types of filters needed. Air is pulled away from the user and filtered or released to the external environment.

 Fume hoods are found in a variety of shapes and sizes- small bench top units are available for space challenged labs, and larger cabinet-type units are available for storage and space demanding experiments. Fume hoods are generally set back against the walls and are often fitted with in fills above, to cover up the exhaust ductwork. Because of their recessed shape they are generally poorly illuminated by general room lighting, so many have internal lights with vapor-proof covers. The front is a sash window, usually in glass, able to move up and down on a Counterbalance  mechanism.

Can A Microbiological Safety Cabinet Be Used As A Laminer Flow Hood

A biosafety cabinet is a primary containment device used with bacterial material. As with work on open bench tops work performed within a BSC be performed carefully and safely. When a BSC is serviced or relocated including replacement of HEPA filters it must be gas decontaminated which involves filling the BSC with a poisonous gas. When this BSC is serviced including replacement of HEPA filters it must be gas decontaminated which involves filling the BSC with a poisonous gas, most commonly formaldehyde gas. Make sure, laminar flow hoods and biological safety cabinets are not interchangeable because they have different functions and technologies.

Basically, laminar flow hoods are used to remove chemical fumes away from the work area. On the other hand, biological safety cabinets or BCS are used to provide both the clean work environment and protection for employees who can create aerosols when working with biological hazards. BCS cannot be used for working with volatile chemicals or radioactive materials. But, laminar flow hoods are rarely found in a clinical laboratory setting.

A laminar flow hood is designed to remove chemical fumes and aerosols from the work area while a biosafety cabinet is designed to provide both the protection for employees as well as for the cleaning purpose. Basically these are the specialized types of laboratory equipments which have some special appeal of its own and now day’s different technologies are coming in the foreign countries which help to do the work much easier and beneficial as well.

Most biological safety cabinets are not classified under this standard because they are not typically used for large quantities of volatile chemicals. So last but not the least that the biosafety cabinet and the laminar flow hood’s working procedures are totally different and that is why it is not possible to use a biosafety cabinet as a fume hood. Both these have different procedures to work and have some features of their own. Most of the foreign countries use these materials in their best way. They try their level best for using these materials in a proper way that is why these are not misusing at all. So it is confirmed and proved that biosafety chemicals cannot work as laminar flow hood.

Biological safety cabinets or BCS are used to provide both the clean work environment and protection for employees who can create aerosols when working with biological hazards. A biosafety cabinet is also known as biological safety cabinet which has some special appeal of its own and this has some own features and characteristics. This biosafety cabinet is sometimes referred as Tissue culture hoods and depending on if and how the cabinet is connected  to the building exhaust small amounts of volatile or toxic chemicals can be handled inside a biosafety cabinet while sterling biological research.

Several different types of BSC are available and these are differentiating by the degree of biocontainment requirement. The primary purpose of a BSC is to serve as means to protect the laboratory worker and the surrounding environment from pathogens. Most biological safety cabinets are not classified under this standard because they are not typically used for large quantities of volatile chemicals.
