A biological safety cabinet (BSC) is a primary engineering control used to protect personnel against biohazardous or infectious agents and to help maintain quality control of the material being worked with as it filters both the inflow and exhaust air..
The biosafety cabinet working principle is mainly to suck the air in the biological safety cabinet outward to keep the biosafety cabinet in a negative pressure state, and to protect the staff through vertical airflow.Jan 31, 2023.
All operations should be performed towards the back of the cabinet away from the user and at least four inches from the front grille.
All materials and equipment should be placed inside the cabinet with care to avoid disrupting airflow that can cause turbulence, cross-contamination and/ or breach of containment..
The Germfree service department can assist with or perform most repairs.
All models of Class II, Type A2 Biosafety Cabinets have a large supply and a smaller, exhaust HEPA filter.
These are sized to provide the entire work area with ultra clean air and to filter particulate mater.
Main Content Biosafety cabinets (BSCs) are one type of biocontainment equipment used in biological laboratories to provide personnel, environmental, and product protection.
Most BSCs (e.g., Class II and Class III) use high efficiency particulate air (HEPA) filters in both the exhaust and supply system to prevent exposure to biohazards.
Perhaps the most valuable parameter of the Class II, Type A2 Biosafety Cabinet is containment without the necessity of working through gloves.
This is accomplished by discharging approximately 30% of the total filtered air each cycle through the exhaust HEPA filter in the top of the unit.
