Robert- I am not aware of any specific list. The EPA does keep lists of what they consider toxic or potentially toxic materials, but I don't think these would be particularly helpful as guidance for this credit. I think this is a case of just using your best judgment on what would need separate exhaust, etc. just as you have done above. I would say that a sterilization room would need to be separated while a lab may not need to be based on your description.
