Heat Resistant Fireproof Explosion Proof Acid & Alkali
Resistant Chemical Laboratory Fume Hood
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.

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
• 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.
