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.
What will you be doing inside the hood?
Try to document as much as you can about the application. What chemicals are used, and how are they used? Is heat involved? What volumes of chemicals will be used at a given time? Most importantly, know the answers to the following questions:
-Do you use Perchloric Acid?
-Do you use Hydrofluoric Acid (HF)?
-Are you working with Radioisotopes and require the use of lead bricks?
What size of fume hood do you need?
This is a four-part question:
I. How wide do you want the fume hood to be? Ample offers fume hoods from 30 inches wide to 16 feet wide, with many options in between.
II. Will there be equipment enclosed in the hood? If the answer is yes, then you must answer parts III and IV.
III. What are the dimensions of the equipment? This information is essential to determining how deep the hood needs to be to house your equipment.
IV. Do you need a bench-top or floor mounted hood? Applications that use extra-large equipment, such as 50-gallon drums, or applications that require equipment to be wheeled into the hood via a cart would require a floor mounted hood.
