Is there a non proprietary specification for fume hoods? I would think size, cubic feet per minute of air movement, and chemical resistance would all be relevant. Anything else? What sorts of numbers would be reasonable? This would be for a Lab Casework Guide Spec.

I have fume hoods in Section 11 5313. Sorry I can't help you with a non-propietary section. Most of our projects don't have them, and in most cases when they do, we have a lab consultant who actually writes those sections.

I see that SEFA 1 is a standard for fume hoods. I will reference that, and give the choice of specifying size and airflow or make and model.

If there is a better way, I'd be happy to know.

Does anyone know if SEFA 7 (Laboratory and Hospital Fixtures) covers lab sinks? I know it covers electrical and plumbing fittings.

Fume hoods range from HS school chemical class hoods to biological safety hoods. There are lots of considerations.
Not sure why you need a generic spec but you need to find out what your clients "wants" and see what they have used, or what their needs are and ask vendors for help. Some government agencies and most private research operations have a spec that fits their need.

Labconco use to have (1999) an excellent master for fume hoods, but I checked 4-Specs and it was not listed

As fume hoods offer the owner's users protection from hazardous material exposure, I would expect the owner to provide the design professional with the performance requirements as part of the owner's OSHA- and insurance- mandated safety program. I wouldn't think that the design professional would want to assume liability for determining the criteria on such an item. If you aren't sure how to define the limits of your practice, consult your E & O insurance risk manager.

In the absence of a knowledgeable owner, I would recommend to them that they hire a qualified consultant to make the recommendation to them.

Labconco has some guides available to download that can help your owner define their needs.

Their guide specs are pretty generic and might serve as a starting point.

Just google them.
