"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. Charlotte J. Head, P.E. Dan

Crowl 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. Dan Crowl Michigan Tech On Tue, Mar 18, 2014 at 4:59 PM, Richard W. Denton <rwdenton3**At_Symbol_Here**gmail.com> wrote: Hi everyone:
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

Not.
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.
