Dan referenced NFPA 45 in his recent email.
I would like to mention that NFPA 45: Standard on Fire Protection for Laboratories Using Chemicals (current edition: 2011) is in
the process of revision. The next edition is scheduled for 2015.

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.
