Product Description

Product Description

Fume hoods should provide a safe and functional workstation for laboratory workers, and are often purchased with vented, flammable, or corrosive storage base cabinetry. Flammable (flash point < 100 °F) and combustible chemicals (flash point >100 °F) impose a fire hazard when stored/used improperly. The most common fume hood safety hazards that arise in laboratories stem from cluttered workstations, improper chemical storage, chemical fume hood incompatibility, and failure to check the hood flow indicator to make sure that it is working properly before starting work.

When choosing a ducted or ductless system, it is important to get all of the necessary components to maintain good lab practices. Cabinets are available for regular, solvent (flammable and combustible), and corrosive (acids or bases) storage. Some cabinets are designed without a bottom for easy access to equipment that can be rolled into and out of the cabinet. If storage is not necessary, simple base stands or carts (for portable hoods) are available to elevate and support the hood and work surface.

Work surfaces vary in composition, abrasion, chemical, and heat resistance. Solid epoxy resin work surfaces provide the highest-level resistance, allowing users to perform tasks with high concentrations of solvents, acids, and bases. Solid phenolic resin stations are intended for high chemical resistance, but are not as hard and durable as epoxy stations. Stations made of composite resin provide the least amount of chemical resistance and are intended for general use only. Stainless steel work surfaces are also available for perchloric acid and radioisotope fume hoods, both of which require ducted exhaust.

 All work surfaces can be purchased with or without spill containment for extra protection, and with cutouts for cup or trough sinks. However, the more plumbing that a hood requires, the less feasible portability becomes. Sinks would likely be plumbed to acid waste systems, and if gas, compressed air, N2, or vacuum turrets are necessary, then disconnecting and reconnecting the unit to move it becomes more of a bother.

More About the Fume Hood

Why You Should Never Store Chemicals in a Fume Hood

There are many equipment- and personnel-related reasons why chemicals should not be stored in a fume hood:
 

1. Obstructed airflow: Too many objects in a laboratory fume hood can obstruct airflow. The main function of a fume hood is to expel and purify contaminated air. Unnecessary objects, chemicals, or equipment increase the risk of blocking proper airflow, increasing the likelihood of a hazardous situation.

 

2. Poor use of expensive, specialty equipment: Fume hoods are expensive and specialized pieces of equipment compared to chemical storage cabinets. Chemical storage cabinets, which are constructed for the purpose of housing specific chemicals, cost much less than a complex fume hood. It does not make sense to leave corrosive or damaging materials in a fume hood when there is a high chance of a chemical-induced incident.

 

3. Lack of necessary safety features: Fume hoods may not be equipped to handle the specific chemicals that need to be stored. Chemicals are extremely specific in the way they need to be stored. Hydrogen peroxide, for example, is a corrosive substance, requiring storage containers to be made of a particular anti-corrosion material.

 

4. Potential to mix hazardous chemicals: Storing chemicals in fume hoods may encourage people to store chemicals together that should always be kept separate. The reactive nature of chemical properties means all materials need correct storage to prevent damaging accidents.

 

5. Potential for interactions with chemical processes: Chemicals stored in a fume hood could interact with other chemicals being used for experiments or processes when the fume hood is in use. Certain chemical interactions can be dangerous, whether leading to a fire, explosion, or other toxic reaction. Improper storage of chemicals puts the user in harm's way, and is always avoidable.

FAQ

What Is a Fume Hood?

A fume hood is a piece of laboratory equipment designed to minimize a person's exposure to hazardous chemicals. The fume hood draws away harmful vapors so lab employees can work with chemicals without the risk of accidental exposure. The air is extracted from the fume hood and filtered to remove dangerous vapors, and then either exhausted outside of the building or recirculated back into the lab.

How Does a Fume Hood Work?

The fume hood works by using a sash (a window that opens or closes to protect the user) to contain the vapor and keep it away from the user's face or to prevent it from drifting out into the rest of the laboratory. Blowers draw in air from the room, through a filter or number of filters within the fume hood and towards an exhaust area.

To safely work in a fume hood, keep all work at least six inches away from the plane of the sash. This will ensure fumes are pulled away from the user. Also, make sure the hood sash remains closed as much as possible and keep the hood slots and baffles free of any obstructions by containers or equipment. Never place your head inside the fume hood when working with chemicals.

The airflow will differ depending on the type of hood you use. For a constant air volume (CAV) hood, the fan has only one speed, providing a stable and continuous airflow. A variable air volume (VAV) hood allows users to adjust the velocity of the exhaust for added versatility, while reduced air volume (RAV) hoods offer lower airflow performance, making them ideal for working with less harmful compounds.

What application will the hood be used for?
Document what you will be doing inside the fume hood. Remember to include what solvents, chemicals and acids are used, the volume whether heat needs to be applied. This will determine whether you need a ducted or recirculating fume hood. Chemicals such as Perchloric Acid and Hydrofluoric Acid will require specific designs or filters.

What size hood is required?
Consider the space you have allocated and make sure it is placed away from doorways and air conditioners. Also consider the dimensions of the equipment that needs to be housed in the hood. You should allow at least 6in of room behind the sash to create the safest working space. If you are using extra large equipment you may need a floor mounted hood, otherwise a bench mounted hood is most popular.

Do you require service fixtures or accessories?
Additional parts such as airflow monitors, and laboratory gas, vacuum and cold-water fixtures can be installed to suit the application. Features like these can save on the costs of electricity and increase efficiency in the laboratory.

Where is the exhaust fan (blower) located?
Will there be a dedicated exhaust fan for this hood or will it connect to a central system? If connected to a central system; will it be constant volume or variable air volume? Ducted fume hoods use the laboratory's existing air duct system and can prove to be an expensive venture as preventative maintenance needs to be administered to ensure that nothing clogs or blocks the duct. Ductless fume hoods rely on neutralizing agents and filters to make the dangerous chemicals less harmful. Because a ductless fume hood does not dispense chemicals directly into the environment, it is also thought to be a much more environmentally safe alternative to traditional ducted fume hoods. It also does not generate a great deal of energy, unlike ducted fume hoods. A ductless fume hood will require more maintenance costs in the form of filter changes.
