What is the primary purpose of a biosafety cabinet (BSC)?
What is the primary purpose of a biosafety cabinet (BSC)?
- To provide a clean workspace for general laboratory work
- To protect the laboratory worker and the environment from pathogens (correct)
- To increase the visibility of the materials being worked on
- To facilitate the use of fume hoods in the laboratory
How is the exhaust air treated in a biosafety cabinet (BSC)?
How is the exhaust air treated in a biosafety cabinet (BSC)?
- It is cooled before being released into the environment
- It is released unfiltered into the laboratory environment
- It is HEPA-filtered before exiting the cabinet (correct)
- It is treated with UV light before exiting the cabinet
What differentiates a biosafety cabinet (BSC) from a laminar flow clean bench?
What differentiates a biosafety cabinet (BSC) from a laminar flow clean bench?
- Clean bench provides better protection from pathogens than a BSC
- BSC is larger in size than a clean bench
- BSC exhaust air is HEPA-filtered, while clean bench exhaust air is unfiltered (correct)
- Clean bench is suitable for work with pathogenic agents, while BSC is not

Study Notes
Biosafety Cabinet (BSC) Overview
- The primary purpose of a biosafety cabinet (BSC) is to provide a safe working environment for handling pathogens and other biohazardous materials.
Exhaust Air Treatment
- The exhaust air in a biosafety cabinet (BSC) is treated with HEPA filtration to remove airborne contaminants and particulate matter.
Differentiation from Laminar Flow Clean Bench
- A biosafety cabinet (BSC) differs from a laminar flow clean bench in that it provides both product protection and personnel protection, whereas a laminar flow clean bench only provides product protection.
HEPA Filtration
- The primary function of HEPA filtration in a biosafety cabinet (BSC) is to capture 99.97% of particles as small as 0.3 microns, ensuring the removal of airborne contaminants and particulate matter.
Comparison to Fume Hood
- A fume hood is not a suitable alternative to a biosafety cabinet (BSC) for working with pathogens because it is designed to capture chemical vapors and fumes, not airborne pathogens, and does not provide personnel protection.
