Product Description
A fume hood essentially looks like an enclosed industrial workbench. To break it down, a fume hood is made up of:
The body: The body of the fume hood contains a work surface, enclosed completely on three sides, on which lab personnel can conduct their experiments / research.
The sash: The sash is the fourth side to the hood, basically a window between the employee and the volatile compounds he or she is working with.
The exhaust duct: The exhaust duct releases any contaminated air to the outside. Usually this duct is connected to the building's HVAC infrastructure, but there are ductless fume hoods available if flexibility, lower cost, and energy efficiency are key drivers for your business or institution.
The baffles: The baffles are slotted panels that control the amount of air flowing into the hood from the surrounding environment

Before usage
1. Before using the fume hood, make sure you have been trained in proper use of the equipment. If you don't know how to use it, ask someone to demonstrate.
2. Understand the potential reactions of the chemicals you are working with (could this chemical explode, liquefy or evaporate under certain circumstances).
3. Open the sash to the proper operating height. Note: If the sash is too high, there is not enough of a barrier between you and the chemicals to provide protection.
4. Check that the air gauge shows that air flow is within the required range.
2.Use eye protection.
3. Try to limit motion around and in front of the hood while you're working. Excess movement could cause the fume hood to vibrate and disrupt airflow.
4. Don't block baffles or exhaust slots while working in the fume hood, this would prevent air from flowing into and out of the hood.
5. Keep all materials at least six inches from the sash opening inside of the hood.
6. When not working in the hood, close the sash and never store any chemicals inside the hood while it's not in use.
7. Know your laboratory's action plan in case of an emergency while handling toxic chemicals.
• 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.
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?
