Thanks for suggesting this, Craig. A more extensive resource from the same source:
https://www.nsta.org/store/product_detail.aspx?id=10.2505/9781933531083
This is The NSTA Guide to Planning School Science Facilities, 2nd edition by LaMoine Motz, James Biehle, and Sandra West. While neither this nor the NSTA paper Craig referenced constitutes binding regulations, they both provide sound reasoning for limiting class sizes to 24 for laboratory instruction. The NSTA Guide is available as a print book or an e-book from NSTA press.

All,
A good source detailing the issues is:
http://static.nsta.org/pdfs/OvercrowdingInTheInstructionalSpace.pdf
It provides good data to justify limiting enrollments.

Cathy,
I was looking into lab occupancy guidance just yesterday. The most iron-clad reason would be if your local fire code dictated that limit. If that's not feasible,
could you provide the square footage and the amount of available bench space?
Sincerely,

My colleague and I are the Chemical Hygiene Officers in our school. We currently only allow 24 students in any lab based science class. We are being asked to justify this enrollment limit. Our current lab space accommodates 24 students.
Does anyone have any resource guidelines that state we cannot go beyond this capacity?
