Product Description

Product Description

Laboratories are often characterized by the use of highly reactive and toxic chemicals and substances. Serving as the hub for all research and development activities, such laboratories need to be equipped with special furniture that has been designed specially to cater to these working conditions. Though there are a number of furniture pieces that have been developed specifically for laboratories, the chemical fume hood has become renowned for their advantageous and effective properties. These fume hoods have been designed to mechanically draw air inside, controlling the contamination of various substances in the lab. And fume hoods continuously control the exposure of the lab objects and specimens to hazardous substances.

Chemical fume hoods are available in different forms depending on their working principle. The most common form of a fume hood is the bypass hood also known as a constant air volume (CAV) fume hood. The CAV hoods are called so because they are used to regulate a constant volume of air, operating to vent out a fixed amount of air all the time. The other popular type of fume hood - the variable air volume (VAV) fume hood is a more advanced one. This fume hood regulates airflow on the basis of the sash height. The VAV hoods are generally equipped with a monitor to check which mode they are working on, and they also feature an emergency purge option.

    More About the Fume Hood

    Ventilation devices are used to capture and remove the contaminants (gas, vapour, or dust) away from the users and out of the laboratory. Fume hood (fume cupboard or fume closet) is a local ventilation device found in all laboratories.

    Fume hoods control contamination by drawing air through the face of the fume hood and away from the users and labs. Through ventilation fume hoods minimise the risk of contamination.

    SASH is a moveable panel on front portion of the fume hoods - often referred to as the fume hood door or window. Sash provides a protective barrier between the lab user and the experiment. The common sash configurations are - vertical, horizontal, and combination sash (vertical + horizontal).

    BAFFLE is the slotted openings along the back of the hood. Baffles work in tandem with the sash to control the air flow in the fume hood and keep the airflow uniform. By eliminating the dead spots and reverse airflow (into the labs), baffles play an important role in safety and fume hood efficiency. In older fume hoods, baffles were moveable partitions, but modern fume hood comes with fixed baffles.

    BODY comprises the fume hood exterior and the interior. The fume hood body contains the contaminants. Well-designed exterior will have a contoured entry (aerodynamic design) to assist airflow into the hood and improve hood performance. The material of construction (MOC) is an important consideration for fume hood, specifically the interior liner material. Since chemicals and gases can corrode the interiors and exterior, MOCs resistant to work being conducted in the fume hood is critical when selecting your fume hood.

    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.
