Hi! First time poster. I think OSHA defers to NFPA (National Fire Protection Agency) on this. I think they say 50 square feet net per student for teaching laboratories. I will try and find and send out the original document I found
stating that.
Aloha,

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?

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?
