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 .
Many engineering controls developed for other industries can be used or adapted for protecting workers from exposure to nanomaterials, including ventilation and filtering using laboratory fixtures such as fume hoods, containment using gloveboxes, and other non-ventilation controls such as sticky mats. Research is ongoing as to what engineering ...
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.
A laboratory that uses a VAV fume hood with a sash that is kept open only during working hours of the day would save a significant amount on energy costs compared to a laboratory using CAV hoods that are fully open 100% of the time, regardless of sash height. [29] [40]
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 ...
