2. Fume hood - Wikipedia

   en.wikipedia.org/wiki/Fume_hood

   A ducted fume hood. Most fume hoods for industrial purposes are ducted. A large variety of ducted fume hoods exist. In most designs, conditioned (i.e. heated or cooled) air is drawn from the lab space into the fume hood and then dispersed via ducts into the outside atmosphere. [5]

3. Vented balance safety enclosure - Wikipedia

   en.wikipedia.org/wiki/Vented_Balance_Safety...

   For example, a single six-foot hood operating 24/7/365 costs over $5,000/year to operate. [1] [2] In addition, CAV hoods do not react rapidly to airflow disturbances (turbulence) within the hood or within the laboratory and, hence, their sole purpose of containment and protection can be seriously compromised.

4. Biosafety cabinet - Wikipedia

   en.wikipedia.org/wiki/Biosafety_cabinet

   Fume hood Glove box A biosafety cabinet ( BSC )—also called a biological safety cabinet or microbiological safety cabinet —is an enclosed, ventilated laboratory workspace for safely working with materials contaminated with (or potentially contaminated with) pathogens requiring a defined biosafety level .

5. Laminar flow cabinet - Wikipedia

   en.wikipedia.org/wiki/Laminar_flow_cabinet

   Despite their similar appearance, a laminar flow cabinet should not to be confused with a fume hood. A laminar flow cabinet blows unfiltered exhaust air towards the worker and is not safe for work with pathogenic agents, [ 2 ] : 13 [ 3 ] while a fume hood maintains negative pressure with constant exhaust to protect the user, but does not ...

6. Kitchen hood - Wikipedia

   en.wikipedia.org/wiki/Kitchen_hood

   Extractor hoods may be ducted (or vented) or ductless (or recirculating). Ducted hoods blow the gases to the outdoors; ductless hoods filter the air, often using activated charcoal, to remove odor and smoke particles from the air and then release the cleaned air back into the kitchen. A ducted system removes of all forms of airborne ...

7. Engineering controls for nanomaterials - Wikipedia

   en.wikipedia.org/wiki/Engineering_controls_for...

   A fume hood is an example of an engineering control that uses local exhaust ventilation combined with an enclosure to isolate a worker from nanomaterials that may become airborne. Engineering controls for nanomaterials are a set of hazard control methods and equipment for workers who interact with nanomaterials .
