Product Description

Product Description

Fume hoods that are of the same size and type and in the exact same location in multiple identical laboratory rooms need not all be tested if the laboratory rooms have the same airflow characteristics. This would include ventilation system configuration, airflow quantities and airflow components including the air diffusers and diffuser locations. Thus, if a facility has many laboratory rooms that are duplicates of each other and the room airflows have been closely set to the same parameters or specifications, a sampling of fume hoods may be tested (termed a sample group) rather than testing each and every fume hood.

To qualify as part of a "sample group" the fume hoods must all be in the exact same location in each of the "identical" laboratory rooms. If a room has multiple fume hoods, each different fume hood location then establishes a separate
sample group. (Thus, if a room has four fume hoods, each of the four fume hoods would be in one of four different sample groups.)

More About the Fume Hood

Once a fume hood is installed and set up in an actual laboratory room, it is recommended that tracer gas containment tests be conducted to determine the appropriate face velocity necessary to maintain a desirable level of containment. Once the average face velocity that will provide the desired containment level is determined, that face velocity can serve as a reasonable benchmark for safe fume hood operation.

This assumes that the room conditions essentially remain as they were when the fume hood was tested and that the fume hood users follow safe fume hood working practices. Note that since a fume hood is not an airtight enclosure, perfect or 100% containment is not generally attainable or even necessary.

The level of containment that is necessary should be established by facility personnel who are responsible for worker safety in consideration of the hazard level posed by the chemicals. If the chemicals or substances that will be present are so toxic or hazardous that 100% or near 100% containment is required, than an airtight glove box should be utilized rather than a 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

6 Questions to Ask When Buying a Fume Hood:

-Which chemicals will you use within the hood?

-Is a ducted or ductless hood best suited to your needs and available space?

-Where will you place the fume hood in the lab? Consider workflows, access to external exhaust systems, and competing air patterns.

-What size fume hood will best suit your needs? Be sure to consider what (if any) equipment will be enclosed in the hood.

-Are any service fixtures or accessories such as airflow monitors, electrical outlets, water, or gas fixtures required?

-Are base cabinets for acid, solvent, or non-chemical storage required?
