Product Description
Product Description
Fume-hoods are probably the most important pieces of protective equipment in the Chemistry laboratory.
Fume-hoods are designed to protect against hazards from toxic, dangerous or otherwise obnoxious material by dragging airflow away from the user and so preventing harmful vapours being inhaled or otherwise ingested.
Ventilation is normally achieved by a single extractor fan powering several hoods in varying locations and on different building floors - this arrangement leaves all of these fume-hoods at risk following the failure of the single fan. The single fan also runs at a fixed speed so that extraction rate from any specific hood depends upon the open or closed state of sashes in the remaining hoods on the stack. Most of the Standard hoods have no warning of fan failure apart from physical indicators e.g. toy windmills or paper tissues rigged by the users. In the event of an Emergency Alarm, Standard fume-hoods remain in operation.
While fume-hoods are designed to protect the user against hazards from other sources e.g. from toxic or obnoxious material or from flammable materials such as solvents, their misuse can lead to them affording less protection than expected or being hazards in their own right.
The rating of the fume-hood may not be sufficient to cope with the materials used.
-The effectiveness of a fume-hood is much reduced if they are open too wide or cluttered with apparatus that interferes with the smooth flow of air.
-Fume-hood fans, especially those on the Standard models, are susceptible to failure. This means that the draft also fails leaving the hood effectively useless.
-The front sash of Standard fume-hoods is made up of a very heavy sheet of glass enclosed in a heavy wooden frame. Accidents have occurred when the sash cords have broken allowing the front to crash down.
-Chemicals stored in a fume-hood that is in active use for chemical work represent potential additional hazards in the event of an accident.

More About the Fume Hood
To maintain effectiveness and performance and to minimize exposure
---All operations should be performed at least 6 inches inside the hood
---Avoid rapid movements, such as opening & closing doors, that can create cross-drafts and disrupt airflow
---Keep sash as low as possible. The glass provides a barrier against a spill, splash, or explosion.
---Chemicals and equipment should not be stored permanently inside the hood
---The hood sash or panels must not be removed from the hood or altered.
---Close sash when hood is not in use
---Check the air flow monitor periodically. If the monitor is alarming, do not use the fume hood.
---Certain chemicals used in large quantities such as perchloric acid, hydrochloric acid, and hydrofluoric acid should not be used in a chemical fume hood that is not approved for their use.
---Radioactive materials may only be used in chemical fume hoods certified by the Radiation Safety Office.

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
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?
