• 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

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!
