Product Description

Product Description

A chemical fume hood is an exposure control device and its purpose is to contain hazards and protect the user from exposure. A fume hood is also part of the overall laboratory mechanical system and there are a variety of potential causes of failure that can occur, both within and outside the user's control. A cause of failure that is often overlooked is the user's own work practices.  

The only way to know for sure if a hood is losing containment is to run a test. When doing containment testing, at least 25 percent of failures are caused by user work practices. If a fume hood is performing poorly, the lab manager may not be able to replace the hood or revamp the laboratory ventilation system, but they can educate the user to help protect themselves by ensuring good practices and expanding their knowledge of how fume hoods perform best

The biggest challenge with fume hood performance is that users usually cannot see the hazards-most are invisible and odorless. Therefore, there is no easy way to know if your fume hood is working properly and protecting you. Many think that face velocity, which is defined as the speed of the air entering the sash opening, is an indication of safety.

Face velocity had been used historically as the primary indicator of laboratory hood performance for several decades. However, studies involving large populations of laboratory fume hoods tested using a containment-based test like the ANSI/ASHRAE Standard 110 reveal that face velocity alone is an inadequate indicator of hood performance. In fact, most hoods that fail containment testing have acceptable face velocity readings.

    More About the Fume Hood

    A fume hood is an enclosed work space in a laboratory that prevents the outward flow of air. Fume hoods cab be designed for work with inorganic or radioactive materials, or with biological materials. Biological fume hoods can be equipped with filters, to ensure that the air entering and exiting the cabinet is sterile. This minimizes the risk of exposure of laboratory personnel to biological agents that could be a health threat. Also, the work surfaces and materials inside the fume hood are protected from contamination from airborne bacteria or viruses . The latter is of particular relevance in some viral research, where the tissue surfaces used to grow the virus are prone to contamination.

    1. Ensure the fume hood is labeled with a certification date of less than one-year prior. Verify sufficient inward airflow before using a hood by checking the hood's airflow indicator.


    2. Maintain hood sash at or below the maximum height indicated by an arrow on the side of the fume hood. Close the hood sash when not working in the hood.

    3. Avoid rapid movements at the face of the hood, as they tend to create competing air currents and reduce the ability of the hood to contain air contaminants.

    4. Equipment used in hoods should be placed securely on blocks to allow air to flow under and around the equipment.

    5. Keep chemical sources and equipment at least six inches away from the face or rear of the hood.

    6. Minimize equipment and chemical storage placed in the hood to avoid dead air spaces or eddies and to prevent blocking back baffles.

    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.
