A fume hood (sometimes called a fume cupboard or fume closet) is a type of local ventilation device that is designed to limit exposure to hazardous or toxic fumes, vapors or dusts.
A fume hood is typically a large piece of equipment enclosing five sides of a work area, the bottom of which is most commonly located at a standing work height.
Two main types exist, ducted and recirculating (ductless). The principle is the same for both types: air is drawn in from the front (open) side of the cabinet, and either expelled outside the building or made safe through filtration and fed back into the room. This is used to:
-protect the user from inhaling toxic gases (fume hoods, biosafety cabinets, glove boxes)
-protect the product or experiment (biosafety cabinets, glove boxes)
-protect the environment (recirculating fume hoods, certain biosafety cabinets, and any other type when fitted with appropriate filters in the exhaust airstream)
Secondary functions of these devices may include explosion protection, spill containment, and other functions necessary to the work being done within the device.

Close the Sash for Safety
The sash on a fume hood serves many purposes, but the most important one is to protect persons working in the laboratory. When the sash is closed it prevents any "leakage" of chemical fumes from the hood.
A closed sash also protects you from "escapes" caused by accidents. Shattered glass, chemical spills, and vapors are contained in the hood if the sash is closed and an "event" occurs.
Closing the sash improves overall hood performance for other hoods in the lab and within the building. Also, in case of a power outage or hood ventilation failure, chemical vapors will not back up into the laboratory. Closing the Sash for Safety is a very healthy habit to develop
• Hoods should be evaluated by the user before each use to ensure adequate face velocities and the absence of excessive turbulence.
Do you require service fixtures or other accessories in the fume hood?
These include (but are not limited to) airflow monitors, electrical outlets, compressed air, laboratory gas, vacuum and cold water fixtures. Faucets are also available. Finally, do the fixtures need to be factory installed, or will the installer handle that at the job site by using field-installed kits?
What about required accessories outside of the fume hood?
Do you need a work surface and base cabinets, or will you be using existing casework to support the hood?
If you do need base cabinets, do you need acid storage, solvent storage or non-chemical storage?
Do you need ductwork from the hood to the roof, or will your HVAC contractor provide it?
How will the fume hood be exhausted?
Every fume hood needs a blower, and it is often misconceived that a blower comes attached to a fume hood.
Will there be a dedicated blower (exhaust fan) for this hood, or will it connect to a central exhaust system?
If it connects to a central system, will it be constant volume or variable air volume
