Hello Everybody,

What is the consensus for laboratory fume hoods when the system's connected to the general fire alarm, should the system automatically turn the fume hoods ON or OFF when the general fire alarm sounds?  The priority for people is to get out, and not look around for things to turn ON or OFF - we let the automation handle that part.  We have conflicting opinions between knowledgeable people who have good reasons to go either way on that. 


The fume hoods are standard built-in ducted devices that are hepa-filtered at the roof stage.  They're strictly working hoods, only enough solvents and other materials are used inside for doing the task at hand (not used for storage or anything else that might cause unnecessary hazards or obstruct efficient air flow). 


Thanks for sharing your opinions.

Wouldn't it be really cool if, included in the panel, there was an industrial ventilation engineer.  I know one near Boston who is both a P.E., CIH.  But there must be others.   It is my experience that the slip ups often occur in the unseen tangle of ductwork, energy saving devices and exhaust stack design.

I'm pleased to let the list know that four organizations are partnering to put 
on a day long "Fume Hood Design for the 21st Century: A Cross-Disciplinary 
Workshop". The goal of the workshop is to develop a report that describes key 
questions that should be considered at the institutional level in developing 
standards for fume hood performance and options for answering those questions. 
For many institutions, this is an ongoing challenge, given the changing nature 
of the sciences hoods support; the complex group of stakeholders involved in 
designing and operating lab ventilation system; and the changing lab ventilation 
technologies that have emerged in the last decade.
We have begun the planning process for the workshop content. The current 
schedule of the workshop and an outline of the issues to be discussed can be 
found at
This is a blog-based site, so viewers have the ability to comment on the 
questions we are considering. We'd appreciate feedback people have on the topics 
currently identified and others that should be considered as part of this 
The co-sponsors of the workshop are:
- the New England Chapter of the International Institute for Sustainably 
- the American Chemical Society Division of Chemical Health and Safety,
- the Campus Consortium for Environmental Excellence, and
- the Campus Safety, Health and Environmental Management Association.
The workshop will take place on October 29, 2014 from 9 AM - 3 PM Eastern 
Daylight Time at the Four Points Sheraton in Norwood, MA. Because we expect that 
there will be national interest in this topic, distance participation options 
are also available; contact Ralph Stuart at secretary**At_Symbol_Here** for more 
Let me know if you have any questions about this.
- Ralph
