1. 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.

3. More About the Fume Hood
Why Workplace Practices Matter
Fume hoods offer an excellent source of protection against toxic
chemicals and substances because of their effective fume hood exhaust systems. However, if not used or maintained properly, their
effectiveness will suffer because the exhaust system may not
completely remove dangerous particles that are present.
Implementing procedures at your workplace that ensure fume hoods
are properly maintained and used is essential to following state
and federal regulations, as well as protecting your workers.
Before beginning work, one of the most important practices lab
technicians should conduct is to ensure the exhaust fan is working.
The exhaust system performs the main job of a hood, so if not
working properly, the hood will not operate effectively.

5. Fume Hood Maintenance
• Hoods should be evaluated by the user before each use to ensure adequate face velocities and the absence of excessive turbulence.
• In case of exhaust system failure while using a hood, shut off
all services and accessories and lower the sash completely. Leave
the area immediately.
• 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.

7. FAQ
6 Questions to Ask When Buying a Fume Hood:
-Which chemicals will you use within the hood?
-Is a ducted or ductless hood best suited to your needs and
available space?
-Where will you place the fume hood in the lab? Consider workflows,
access to external exhaust systems, and competing air patterns.
-What size fume hood will best suit your needs? Be sure to consider
what (if any) equipment will be enclosed in the hood.
-Are any service fixtures or accessories such as airflow monitors,
electrical outlets, water, or gas fixtures required?
-Are base cabinets for acid, solvent, or non-chemical storage
required?
