Product Description

A laboratory fume hood is a ventilated enclosure where hazardous materials can be handled safely. The purpose of the hood is to contain contaminants and prevent their escape into the laboratory. This is accomplished by drawing (by air flow) contaminants within the hood's work area away from the user thereby preventing and minimizing inhalation and contact with hazardous materials.

To create airflow into the hood, an exhaust blower "pulls" air from the laboratory room into and through the hood and exhaust system . A baffle, airfoil, and other aerodynamically designed components control the patterns of air moving into and through the hood.

Fume Hoods must be located away from heavy traffic aisles and doorways so that persons exiting the lab do not have to pass in front of the fume hood. The potentially dangerous portion of an experiment is usually conducted in a fume hood. Many lab fires and explosions originate in fume hood and a fume hood located adjacent to a path of egress could trap someone in the lab.

There must be two exits from rooms where new fume hoods are to be installed. If this is not feasible, the fume hood must be situated on the side of the room furthest from the door. A fire or chemical hazard, both of which often start in a fume hood, can render an exit impassible. For this reason, all labs with fume hoods are required to maintain two unblocked routes of egress

More About the Fume Hood

Types of Fume Hoods

• General Purpose, Bench Top Fume Hood

• Distillation Fume Hood
A distillation hood is characterized by a low worktop height which results in a large working height for the operator. This allows tall distillation equipment to be installed and mounted in the work chamber. Otherwise, it has similar features to that of a standard fume hood.

• Perchloric Acid Fume Hood
Perchloric acid reacts violently with organic materials. Dried perchloric acid is also highly explosive. Therefore, perchloric fume hoods require built-in water wash down systems in order to prevent perchlorate salt deposits. Interior liners are made of acid resistant materials like stainless steel. Interior corners are coved to aid in cleaning. All procedures that use perchloric acid must be confined to a perchloric fume hood, to prevent dangerous reactions with other chemicals.

• Radioisotope Fume Hood
Radioisotope fume hoods are constructed specifically to protect users from radioactive materials. They have specially constructed worktops to withstand the weight of lead shielding plates, and may also have lead laced sashes. Interiors are made of stainless steel with coved corners to aid in decontamination.

• Acid Digestion Fume Hood
Acid digestion fume hoods have special liners manufactured of acid resistant materials such as unplasticized PVC. For acid digestion applications involving high service temperatures, other materials such as PVDF may be used. Sashes may be made of polycarbonate to resist hydrofluoric acid etching.

• Floor Mounted Fume Hood
Floor mounted fume hoods are used for applications which require large apparatus. As the name implies, these hoods are floor mounted without any work surface. This facilitates the transfer of equipment and materials into, and out from the hood. Floor mounted hoods are sometimes referred to, although wrongly, as walk-in fume hoods.

• Demonstration Fume Hood
A demonstration hood has all 4 sides made of safety glass, and this hood is commonly used in educational institutions to allow students to easily view the teachers' demonstrations inside the fume hood from all angles, enhancing efficiency in teaching laboratories.

• Ductless Fume Hood
Ductless fume hoods utilize activated carbon filtration to adsorb chemical vapors and fumes. These hoods recirculate air to the laboratory, and are growing in popularity because of energy savings and the green movement.

Detailed Photos 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.
