All,

A good source detailing the issues is:

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?
