Product Description
Product Description
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.

More About the Fume Hood
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

Fume Hood Maintenance
• Hoods should be evaluated by the user before each use to ensure adequate face velocities and the absence of excessive turbulence.
• Fume hoods should be certified, at least annually, to ensure they are operating safely. Typical tests include face velocity measurements, smoke tests and tracer gas containment. Tracer gas containment tests are especially crucial, as studies have shown that face velocity is not a good predictor of fume hood leakage.
• Laboratory fume hoods are one of the most important used and abused hazard control devices. We should understand that the combined use of safety glasses, protective gloves, laboratory smocks, good safety practices, and laboratory fume hoods are very important elements in protecting us from a potentially hazardous exposure.
• Laboratory fume hoods only protect users when they are used properly and are working correctly. A fume hood is designed to protect the user and room occupants from exposure to vapors, aerosols, toxic materials, odorous, and other harmful substances. A secondary purpose is to serve as a protective shield when working with potentially explosive or highly reactive materials. This is accomplished by lowering the hood sash.FAQ
1. 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?
2. 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.
3. 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?
4. 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?
5. 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?
6. Do you need a built-in blower or a remotely located blower?
Built-in blowers are easier to install (and therefore less expensive), but they can be noisy and they put the ductwork under positive pressure, so they should be reserved for non-hazardous applications, short duct runs and instances where a remote blower cannot be installed (such as a mobile lab).
Remote blowers, though more complex to install, can be sized for the specific situation and keep the ductwork under negative pressure for safer operation.
7. What is the layout of the duct run?
Will the duct go directly to the roof, or does it need to make some turns before reaching the roof? What diameter of duct will be used? Once the duct penetrates the roof, a final 90-degree elbow will be needed to turn the duct horizontal, then three to five feet of straight duct is needed between the elbow and blower.
Finally, the exhaust stack should include a zero-pressure weathercap (not a gooseneck, mushroom cap or anything that would block the exhaust from discharging in a vertical, up direction), and should terminate at least 10 feet above the roofline to allow the fumes to reach the airstream and not be returned into the building's air handling equipment.
