Audited Supplier A fume hood is a ventilated enclosure in which gases, vapors and fumes are captured and removed from the work area. An exhaust fan situated on the top of the laboratory building pulls air and airborne contaminants through connected ductwork and exhausts them to the atmosphere.
The typical fume hood found in Princeton University laboratories is equipped with a movable front sash and an interior baffle. Depending on its design, the sash may move vertically, horizontally or a combination of the two and provides some protection to the hood user by acting as a barrier between the worker and the experiment.
The slots and baffles within the hood direct the air and, in many hoods, can be adjusted to allow the most even flow. It is important to prevent the baffles from becoming blocked, by excessive material storage or equipment, since this significantly affects the exhaust path within the hood and as a result, the efficiency of hood capture.
The beveled frame around the hood face, called the airfoil, allows for even air flow into the hood by eliminating sharp curves to reduce turbulence.

5. FAQ
Does my work require a fume hood?
Use of a chemical fume hood is required to enclose work involving toxic gasses, reactive or explosive materials, volatile chemicals, carcinogens, flammable chemicals, hazardous substances and processes producing aerosols or nuisance odors.
Exhaust fume hoods vent air from the work area directly outside of the building by connecting to the facility's ducted exhaust system. Ductless exhaust, or stand-alone, fume hoods use integral blowers to draw air away from the work area through a set of filters before safely releasing the air back into the ambient lab. Ductless hoods commonly use a two-stage filtration system composed of a charcoal filter for vapor containment and a final HEPA filter for particle containment. Charcoal filters capture chemical vapors with varying degrees of efficiency; review your list of chemicals - along with solvent concentrations and aliquoted volumes - with your fume hood specialist to ensure the appropriate filter is purchased. Laboratory fume hoods are required to safely enclose chemicals, such as methanol, that are not captured efficiently by charcoal filtration. Small-footprint ductless fume hoods fit onto crowded benchtops or into areas of the lab without access to the facility exhaust system. The effectiveness of a ductless exhaust hood is contingent upon regular filter maintenance; talk to your hood specialist or EH&S representative to prepare a standard filter replacement schedule.
Do I need a light duty chemical hood or a high-performance fume hood?
Although the primary purpose of a laboratory fume hood is operator safety, demand has increased for hoods designed to carry lower operating costs and reduced environmental impact. As fume hoods consume an average of 70,000 cubic feet of pre-conditioned air per hour, their operating costs are tied primarily to their air consumption, cited as volumetric rate (CFM) or face velocity (fpm). High-performance fume hoods - also called green ventilation hoods, high efficiency hoods or low-flow hoods - provide the highest level of containment at the lowest operating cost. High-performance fume hoods are designed to safely operate while maintaining a face velocity of 60 fpm, the lowest acceptable ASHRAE performance standard as outlined by SEFA. In addition to reduced face velocities, high efficiency fume hoods can integrate with Variable Air Volume (VAV) building automation systems to ensure minimum allowable room air changes, safe room pressurization and desirable temperature and humidity set points. A conventional light-duty, or by-pass, fume hood carries a lower up-front cost than a high-performance hood, but does not include design features allowing for reduced air volume ventilation or VAV integration. Most light-duty exhaust hoods safely operate at face velocities between 90 - 110 fpm, equal to an increase in air consumption of 30 - 50% annually. To decide between a light-duty chemical hood and a high-performance fume hood, a life cycle cost analysis is required to compare energy cost, ambient climate conditions and usage rate.
Does my work require a benchtop fume hood, walk-in hood or canopy hood?
Bench top fume hoods are mounted on an existing work surface, or casework, to create a negative-pressure environment for fume containment. A walk-in fume hood, or floor-mounted hood, includes no work surface or cabinetry, allowing the user to place large items into the hood at floor level. A canopy fume hood is installed on the wall or suspended from the ceiling; it does not include a hood frame or physical barrier between the fume hood area and the ambient lab. Benchtop fume hoods are designed to enclose singular processes on a crowded benchtop, like small-scale solvent evaporation or ethanol extraction. Walk-in fume hoods can accommodate bulk storage systems, like 50-gallon drums, large processing equipment and heavy items transported by lab carts. Canopy exhaust hoods are designed to vent non-toxic materials like heat, steam and nuisance odors emanating from ovens, steam baths or autoclaves.
Should I purchase a remote blower or dedicated, built-in blower with my lab fume hood?
Built-in blowers, or exhaust fans, are installed within the body of the fume hood and positioned above the work area. Remote exhaust blowers are installed on the building exterior and connect to the fume hood through a duct system. Built-in blowers are easier to install and less expensive, but can be noisy. As integral, built-in blowers can place sections of the ductwork under positive pressure, thus pushing contaminants through duct leaks back into the lab, they are recommended for non-hazardous applications, short duct runs, or mobile labs. Remote blowers, though more expensive and complex to install, can be sized for the specific situation, taking into account the duct diameter and run length and quantity of 90-degree or 45-degree elbow turns. Remote blowers keep the ductwork under constant negative pressure; any leaks in the duct system will draw air into the duct for exhaust from the building. Remote blowers include exhaust stacks and zero-pressure weather caps, ensuring the exhausted air is terminated at least 10 feet above the roofline to prevent fumes from returning to the building through the HVAC system.
