Charlotte,
In theory, undergraduate labs are supervised, either by the instructor or teaching assistant. Undergraduate labs, do NOT routinely use pyrrophoric compounds. Nor do the undergraduate labs engage in the use of extremely aggressive oxidizers or corrosives.
Graduae and post-graduate labs, are by practice, unsupervised. In theory (not necessarily in practice), the grad student or post-grad has several semesters or quarters of experience and is bnetter trained to recognize and manage risks. The graduate and post-graduates routinely conduct their research at all hours of the day and night. Their experiments may run several days.
Respectfully yours,
Paul

I have a question regarding NFPA 45. I am wondering how undergraduate research labs fit into the definition of Instructional laboratory units. As defined in the 2011 version of NFPA:
"used for education past the 12th grade and before post-college graduate-level instruction for the purposes of instruction of six or more persons for four or more hours per day or more than 12 hours per week. Experiments and tests conducted in instructional lab units are under the direct supervision of an instructor. Lab units used for graduate or post-graduate research are not to be considered instructional lab units."
The definition specifically excludes graduate and post-graduate research. Why doesn't it exclude "undergrad research" too? This would be situations where the instructor is not always present, but labs where several undergraduate students are working at the same time.
Thank you.

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.
