Our administration asked us to increase the number of students in our introductory chemistry course from 30 to 35. We have enough equipment to handle 5 more students per class. Are there guidelines regarding the number of students it is safe to have in a class? The instructor is the only non student in the class: the lab aid cannot assist in every class because some classes meet at the same time or overlap. We have 6 lab tables 17ft by 2.5ft. The lab tables are separated by 5ft. There is 3ft of space on either side of the tables. I would send for your book on safety but I need an answer as soon as possible. If you have any comments, they would be greatly appreciated. thanks Dr. David Zoller Chair of Physical Science Olive-Harvey College (773)291-6540
