Hi Melissa:


I’d be concerned not just about exhaust from the lab building being drawn into the cafeteria but food exhaust being drawn into your lab building.  I think there may be height requirements for food exhaust, too.


A wind tunnel study would be a good idea.  RWDI is a company we’ve worked with.  They have a variety of practice and it may be worth it to talk with them.  I have no economic interest in RWDI.

I would appreciate your help again with a lab design issue. My fabulous engineering colleagues want to locate a new lab next to a cafeteria, sharing a wall. I do not like this idea. The cafeteria is a full kitchen cafeteria where it will have its own exhaust system right next to the chemical laboratory. Their solution is to have the kitchen exhaust stacks “short” and the chemical lab exhaust stacks “high” to try & eliminate the occurrence of any chemical exhaust being drawn into the kitchen intake. I have objected to this but they want a “regulation” that says they can’t do this. My professional judgment isn’t enough.


Any ideas?
