The booklet from the American Chemical Society: Safety in Academic Chemistry
Laboratories (Accident Prevention for Faculty and Administrators, 7th
Edition) states:"Laboratory instructors are responsible for the safety of
their laboratory students; no more than 25 students should be assigned at
the same time to work in a laboratory under the supervision of an
instructor." We set the max at 24 for the first freshmen course although we
might let one more in assuming the enrollment will go down. An odd number
is inconvenient if they are working in pairs. The second freshman course as
well as the quantitative analysis course have limits of 22 this semester.
We try to keep the Organic courses at 18 or lower. The students can just
get themselves into a lot more trouble in these courses so "prudent
practice" calls for fewer students for the instructor to try to keep safe.
Higher level courses are certainly smaller and part of this has to do with
limits in space and equipment.
