Product Description

Product Description

Chemical fume hoods are highly energy-intensive as they continuously remove conditioned air from a space. Constant volume chemical fume hoods can use more than 3 times as much energy as a single family home on an annual basis. The energy required for filtering, moving, cooling or heating, and cleaning air is the largest cost in lab facilities. Innovations in chemical fume hood technology and design have succeeded in reducing airflow through chemical fume hoods while maintaining, or increasing, safety and performance.

Variable air volume (VAV) chemical fume hoods exemplify an innovation in chemical fume hood technology.

VAV systems adjust the amount of air that passes through a chemical fume hood while maintaining a minimum velocity for safety. The reduction in air passing through the chemical fume hood when the sash is lowered results in a reduction of outside air that must be reconditioned to replace the air exhausted. The less outside air that must be conditioned results in lower building costs.

More About the Fume Hood

Chemical fume hoods are the primary engineering control for capturing and removing hazardous airborne contaminants in laboratories. Use a chemical fume hood when handling chemicals that have high acute toxicity, are carcinogens, mutagens or are reproductive toxins; anytime your work involves potential exposure to chemicals; chemicals are flammable, corrosive or irritating, reactive, potentially explosive; or where heating or agitation may cause chemicals to spatter or aerosolize. Chemicals with particularly low odor thresholds,should also be handled in a chemical fume hood, regardless if hazardous or non-hazardous.

There may be instances where there is only a very low risk of exposure to the chemicals described above (e.g., use of minimal quantities in a closed system). A risk assessment can be performed to determine if a chemical can be safely handled outside of a chemical fume hood.

Consider upgrading to a glove box or other isolation device for particularly hazardous substances, toxic gases, and highly reactive or explosive/pyrophoric materials, as chemical fume hoods are, under the best of circumstances, only certified to a containment performance of less than 0.1 part per million (ppm) leakage rate.

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.
FAQ

Why do fume hoods use so much energy?
It's the air being sucked through the fume hood, not the fume hood itself that consumes so much energy. For health and safety reasons, labs use 100% outside air which must be heated or cooled for comfort before it is brought into the lab. In addition to the energy required to condition the air, a significant amount of additional electricity is required to run large fans to move the air through the building and through the fume hoods.

How does shutting the sash save energy?
Most fume hoods at Stanford are variable air volume (VAV), meaning that the fume hoods are designed to vary the air flow based on how wide open the sash height is. Sash position is connected to the building's ventilation system so that a building's fan speed and the volume of air moved is reduced when the sash is lowered.

Is it safe to shut the sash?
The sash is an important safety barrier between the fume hood interior and the laboratory, protecting the lab user. Sashes should be opened only to set up or modify an experiment. At all other times, shutting the sash is safest. When the sash is shut there is still some air flow through the hood to remove any fumes.

How do I remind myself and my roommates to close the sash?
You can post a sticker, like the one shown in the picture below, to remind yourself and your lab mates to close the sash when not in use. The sticker also educates new fume hood users tha a lower sash is safer, and that the sash should only be open when setting up and modifying experiments.

What other fume hood practices can reduce my energy consumption?
• Never use a fume hood just for storing chemicals - they belong in a safety cabinet, which doesn't require huge volumes of air.
• If your fume hood has an occupancy switch, turn it off when not in use.
• If your group is no longer using a specific fume hood, consider having it locked and de-commissioned so air no longer flows through it.
