Ducted & Ductless Fume Hoods

- Primary control device for protection of lab personnel from exposure to toxic chemicals - Partially enclosed workspace that is exhausted to the outside of the building - Suctions relatively high air flow through the front opening and exhausting hazardous pollutants out of the laboratory, where it will be infinitely diluted in the atmosphere What are Fume Hoods?

1. Bypass 2. Baffles 3. Sash 4. Airfoil Basic Features

Bypass – Openings on the hood body above the sash. As the sash is lowered, the openings are gradually opened such that there is inflow of air to compensate for the shrinking of the sash opening. Baffles -- Partitions used to create slotted openings along the back of the hood body. Baffles keep the airflow uniform across the hood opening, thus eliminating dead spots and optimizing capture efficiency. Basic Features

Sash - The sliding “door” to the hood. The sash should be held in a low position (around 20 inches) when working in the hood and closed completely when the hood is not in use. - The sash may be temporarily raised above this position to set up equipment, but must be returned to the optimum sash height setting prior to generating contaminants inside the hood. Basic Features

Airfoil - Located along the bottom and side edges the airfoil streamlines airflow into the hood - Prevents creation of turbulent eddies that can carry vapors out of the hood - Space below the bottom airfoil provides source of room air for the hood to exhaust when the sash is fully closed Basic Features

- Volume of airflow into hood remains more or less constant. As the sash is closed the airflow velocity into the hood increases. - Air bypass incorporated above sash provides additional source of room air, reducing the rate of increase of face velocity as sash is lowered. Design Styles Constant Volume Bypass System

Variable Air Volume Hoods - Most sophisticated of the hood types, requiring technically proficient design, installation and maintenance - Maintains a constant face velocity as sash height changes, safe and energy-efficient - Tracks the makeup air to the total exhaust by means of multiple dampers Design Styles

Safety Essentials  Fume hood is not a storage!  Always keep fume hood clean and clear.  Action must be taken immediately if spillage happen. Safety Essentials

 Raise bulky equipment 1-2 inch off the work surface.  Place bulky equipment towards the rear of hood and away from the side walls. Safety Essentials

 Keep sash as low as possible when conducting experiment.  Do not block the airfoil.  Reduce pedestrian traffic in front of the hood  Minimize rapid movement in front of hood.  Always keep laboratory windows and doors closed. Safety Essentials

 Do not use a hood for any function for which it was not intended.  Certain chemicals or reactions require specially constructed hoods.  Perchloric acid hoods shall be made of stainless steel and equipped with a wash down system.  Polycarbonate sash shall be applied when using hydrofluoric acid.  Work involving harmful micro-organisms should be done in a biosafety cabinet, rather than a chemical fume hood.  Close the sash when finished hood work or leaving experiments or chemicals unattended.
