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.
