Study Notes
Biosafety Cabinets (BSCs)
- Open flames are not necessary within the clean environment of a Class II or III BSC because they can create turbulence, disrupt airflow, and potentially contaminate the environment.
- Clean materials should be kept at a recommended distance of at least 12 inches (30 cm) from aerosol-generating activities inside a BSC to prevent cross-contamination.
- The recommended procedure for arranging the work flow inside a BSC is to work from clean to contaminated, following a unidirectional workflow, and keeping the most critical activities, such as inoculation, in the center of the cabinet.
