Also termed "walk-in" fume hoods, floor-mounted fume hoods have a working area that extends from the floor to the bottom of a connected exhaust duct for the use of tall equipment. Despite the name of "walk-in", entering a floor-mounted fume hood in operation while it contains hazardous materials poses a significant risk to the user; [ 63 ] they ...
Fume hoods were introduced about 100 years ago to safeguard personnel working with hazardous materials. While many changes and improvements have been made, the basic concept and design of fume hoods remains the same. Air is drawn from the workplace, around the worker and into the front of the hood, and is then exhausted out of the laboratory.
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 .
A fume hood is an example of an engineering control that uses local exhaust ventilation combined with an enclosure to isolate a worker from airborne gasses or particulates. Ventilation systems are distinguished as being either local or general.
Fume hood Preparation of microbiological samples in a laminar chamber A laminar flow cabinet or tissue culture hood is a partially enclosed bench work surface designed to prevent contamination of biological samples , semiconductor wafer , or any particle-sensitive materials.
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 .
