Others will probably find the code citation for you but our Authority Having Jurisdiction requires 50 sq ft per student per lab.  It effectively limits our enrollment in lab sections to 24, which is fine with me.


Hope this helps,

Sorry, forgot the subject line


I know I've seen space recommendations for an organic chemistry lab at around 100 square feet per person in the lab. For a general chemistry I've seen numbers at about 50-70. For our labs this puts 8 students in each of two rooms for organic lab and 16-18 in each room for general chem (with the teacher). 


Have you seen these numbers, or other numbers, and what is a reference? We have some "bean counters" who are talking 95 sg/ft per student in organic - with half of that as storage in a separate room. This would put 16 students, 2 per hood in a 950 sq ft room for organic.
