OSHA has nothing on this in the General Industry Standard. They only have a set of very rotten air quality standards that can't be exceeded.  How you achieve compliance is pretty much up to you.

Thanks guys, I believe I have more than enough information to assist my department in making the right decision.   Also what is OSHA's regulation on ductless hoods?

Look at this NIH policy document on ductless hoods.  It is from 2005.  That is where I got the NFPA reference for NFPA 45.  It is section 6.4.1.

Hi everyone:
   I was asked by my department to assist in deciding whether to purchase ductless fumehoods  for our undergraduate chemistry labs. We are planning to use these for flammable solvents, and reactions involving  HCl and NaOH.  These hoods will be used by undergraduates for research also.  Any input on the safety issues involved with these equipments versus the regular hoods would be appreciated.
