This work must be carried out by third parties. Labolutions can only validate the BSCs / MVKs if they are connected to the return air duct if required.
Where should BSCS be placed in a lab?
BSCs should be located out of the laboratory personnel traffic pattern. Preferably they are placed at the end of an aisle. BSCs should not be placed near an entryway. If this cannot be avoided they should be placed at least 60” from behind the doorway or 40” from an adjacent door.
When working in a biosafety cabinet What area of the cabinet should samples be placed in for the best protection?
The middle third of the BSC work surface is the ideal area to be used for your experiments and all operations should be performed at least 4 inches from the front grill. Materials placed in the cabinet can cause disruption in airflow, resulting in turbulence, possible cross-contamination, and/or breach of containment.
Where should you place materials you are working with in the biological safety cabinet?
All materials should be placed as far back in the cabinet as possible, toward the rear edge of the work surface and away from the front grill of the cabinet, but still within reach. Similarly, aerosol-generating equipment should be placed toward the rear of the cabinet to take advantage of the air split.
What is the correct working distance from the front of the biological safety cabinet?
Standard operation procedures Minimize movement (especially rapid movements) into and out of the BSC, or in areas near the BSC. Do not block the front grill or rear vents with your arms or other materials. Work at least 4 inches from the inside edge of the front vent.
What biosafety cabinet can be installed in a BSL 2 laboratory?
For Biosafety Level 2 applications involving toxic chemicals or radionuclides, a Class II- B type cabinet must be installed. Class II-B cabinets do not allow in-room venting of exhaust air and are thus appropriate for such uses.
What is the purpose of biosafety cabinet?
Biosafety cabinets (BSCs) are one type of biocontainment equipment used in biological laboratories to provide personnel, environmental, and product protection.
How often must a biosafety cabinet be certified for proper installation and operation?
annuallyBSCs must be certified when installed, whenever they are moved and at least annually [29 CFR 1910.1030(e)(2) (iii)(B)]. Employers should ensure that a risk assessment has been completed and approved for the work to be conducted and to identify the class and type of BSC needed for the operation or procedure.
Do biosafety cabinets require exhaust?
These cabinets should be maintained under a minimum negative pressure of 0.5" w.g. Exhaust air is discharged to the outdoors through double HEPA filters (or HEPA and air incineration).
What is a Class 3 biological safety cabinet?
A Class III cabinet is defined as a totally enclosed, ventilated cabinet with leak-tight construction and attached rubber gloves for performing operations in the cabinet. Class III biosafety cabinets are also called glove boxes.
How many people can work in a biosafety cabinet?
Biosafety cabinets are designed for a single operator. Never work with two or more people at a time in any BSC, regardless of manufacturer, model or size.
What is the difference between a Class 1 & a Class 2 biological safety cabinet?
Biosafety cabinets are divided into three classes: I, II and III. Class I provides protection for the user and surrounding environment, but no protection for the sample being manipulated. Class II provides protection for the user, environment and sample, and is divided into four types: A1, A2, B1 and B2.
What is the primary difference between the Class II type A1 A2 and B1 B2 cabinets?
NSF defines four types of Class II cabinets (A1, A2, B1 and B2) that are distinguished by differences in airflow patterns and velocities, HEPA air filter positions, ventilation rates and exhaust methods.
What is the difference between a biological safety classes I II and III cabinet and a fume hood?
A chemical fume hood protects the user while a biosafety cabinet protects the user, the environment, and the material. Biosafety cabinets have high-efficiency particulate air (HEPA) filters while chemical fume hoods do not.
Which of the preparation should be conducted in biosafety cabinet?
To prepare your BSC for maintenance, certification or repair: Empty the BSC of all items. The cabinet must be completely cleared of any equipment, pipettes, waste, liquids and tubing. Decontaminate the surfaces of the BSC with an appropriate disinfectant, such as a 10% bleach solution followed by 70% ethanol solution.
How biosafety cabinets keep the user and samples safe?
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.
Who or what does a Level 2 biosafety cabinet protect?
A Class II cabinet is defined as a ventilated cabinet for personnel, product and environmental protection for microbiological work or sterile pharmacy compounding.
How does a Class 2 biological safety cabinet work?
A Class II, Type A2 Biosafety Cabinet (BSC) provides personnel, product, and environmental protection through filtered air, laminar or unidirectional air, and a motor blower. Room air is drawn in through the front grill of the cabinet.
Where to place a BSC?
Place your BSC in a “dead space” in the lab to maximize performance . A BSC does not pull as much air as a chemical fume hood. Sources of air turbulence such as opening/closing doors, busy walkways, air vents overhead, etc. will make it difficult for your BSC to function effectively.
What is BSC disposal?
a BSC is being moved out for disposal ( i.e., via demolition/reconstruction waste, VUMC Facilities Management Surplus or VU Plant Operations Surplus ).
Is BSC being moved?
a BSC is being moved to a different lab space and has an incomplete history of use for the currently installed HEPA filters.
Do you clean and disinfect a BSC?
Clean and disinfect all accessible surfaces of the BSC if leaving the cabinet behind in a lab space you are vacating . All accessible surfaces of lab equipment that may have been contaminated with biological materials must be thoroughly cleaned and disinfected before it is passed on to the new occupants or handled by movers. Contact OCRS Biosafety to generate a biosafety equipment release posting for the BSC.
Can you move a BSC?
Do not try to move a BSC yourself! Biosafety cabinets can weigh upward of 600 pounds, and moving them without the proper equipment is unsafe for personnel and can damage the BSC . Utilize Vanderbilt’s resources that are available and have the proper equipment for this purpose. If your cabinet has been gas decontaminated, the certifier will post a decontamination notice on the BSC. Leave this on the cabinet so that those moving it know that it is safe to handle.
Can you use open flames in a BSC?
pH neutral, and. formulated to be compatible with stainless steel. Do not use open flames in the BSC unless absolutely necessary . Open flames will damage the HEPA filter and create turbulence in the work space that can lead to migration of contaminants into or out of the BSC.
Can you install a gas line in a BSC?
Do not install a gas line unless you have consulted with OCRS Biosafety . Because of the recirculating air configuration of the BSC, a gas line inside a BSC can lead to explosions in the event of a leak. Contact Robin Trundy (322-0927) to discuss your procedures needs and for assistance in identifying alternatives if you feel you need a gas line.

SPACE ABOVE BSC TO (LOWERED) CEILING
Engineering and installation advice for recirculating installation or connection to the exhaust air duct of your BioSafety Cabinets. If the workbench is installed in a recirculating mode, we recommend keeping a free space of at least 25 cm above the exhaust HEPA filter.
RISK ANALYSIS
We advise your BioSafety Officer to make a risk analysis. If this risk analysis shows that the safety workbench (s) must be connected to an exhaust air duct (Ø250mm), we strongly advise you to have this done by means of a thimble system. This is as advised in the EN12469 and in accordance with the NSF49 standards.
SUFFICIENT CAPACITY
You must at all times ensure that your drainage system has sufficient capacity to be able to set the channel, when the safety workbench is in operation, to a slight vacuum. When the safety workbench is in operation, it must be possible to set it to a slight underpressure. When using a thimble we advise you to always remove 10-15% extra air.
EXACT PLACE DETERMINATION
