Thanks for all of your suggestions for my 1 hour (yes, 1 hour) presentation to the ASHRAE student section. I've got about 20 students attending tomorrow. I'll go thru some ppt slides the 1st part of the meeting, then I'll take them into a lab and let them use the smoke tubes to verify room pressurization and lab air flow, and then take air flow measurements at the hood with various devices.

I've put all of your great ideas on to 1 slide for a brief discussion and a "to be continued" topic:

• Strobic fans

• Low profile, high velocity exhaust fans

• Phoenix valves

• Room pressurization

• Duct velocities

• Round ductwork is energy and transport efficient =96 still see labs built with rectangular ductwork of an office building

• Constant, auxiliary, variable air

• Bypass, non-bypass, perchloric acid hoods

• Low flow hoods

• Proper location of a FH in a space is critical to the overall success of building ventilation

• Fume hood should not be in the path of egress

• Roof exhaust velocity

• Stack height

• Re-entrainment

• Air modeling studies

• Hood alarms

• Choice of supply diffuser and its location in the room is important to getting the proper air flows patterns

• Biological Safety Cabinets including laminar flow hoods (often used in non-biological "clean" operations) as well as recirculating and ventilated BSCs

• Glove Box

• Snorkel


If anyone wants the ppt, I'll be happy to email it to you.

If anyone has additional ideas (remember - 1 hour), let me know.

Thanks again for all of your help!

I have the opportunity to give a 1 hr presentation to the Engineering student section of ASHRAE that meets on our campus. I am going to talk about fume hoods & lab ventilation. I will give a short presentation and then take them to a lab so they can test face velocity with my various Alnors.

I'm planning on including ASHRAE Industrial Ventilation, ANSI/AIHA Z9.5, SEFA-1, NFPA 45, Laboratory Fume Hoods by G. Thomas Saunders, and Laboratory Ventilation Work Book by D. Jeff Burton as resources.

As a chemical safety professional, what do you wish the graduating Engineering students knew about fume hoods and lab ventilation?

Thanks, as usual, for your input!
