A biosafety cabinet is also easily-confused with a laminar flow cabinet, but like the fume hood is primarily designed to protect the worker rather than the biological samples. This is achieved by drawing surrounding air in and exhausting it through a HEPA filter to remove potentially hazardous microorganisms.
All exhaust air is HEPA-filtered as it exits the biosafety cabinet, removing harmful bacteria and viruses. [2] This is in contrast to a laminar flow clean bench, which blows unfiltered exhaust air towards the user and is not safe for work with pathogenic agents. [3]: 13 [4] Neither are most BSCs safe for use as fume hoods. [2]
Downflow fume hoods are encountered more frequently in applications involving powders, [54] and are comparable to laminar flow cabinets. The laminar flow within these devices is easily disrupted, more so than traditional fume hoods, which can result in exposure to hazards within the hood. [55]
Examples of local exhaust systems include fume hoods, vented balance enclosures, and biosafety cabinets. Exhaust hoods lacking an enclosure are less preferable, and laminar flow hoods are not recommended because they direct air outwards towards the worker. [4]: 18–28
[9]: 12 Examples of local exhaust systems include fume hoods, vented balance enclosures, and biosafety cabinets. Exhaust hoods lacking an enclosure are less preferable, and laminar flow hoods are not recommended because they direct air outwards towards the worker. [11]: 18–28
