You had a very important word in this statement - NET.�

The educational shop/lab areas are 50 square feet net.
Each time a researcher crams in another refrigerator, tank, or piece of floor based equipment that is considered "permanent", they are effectively reducing the number of students that can work in a research lab.�

The occupancies for college classrooms and labs per the International Fire Code (and likely consistent with the Life Safety Code - I do not have a copy handy right now) are considered B (business occupancies).  Business areas require 100  square feet gross.  



In addition to the basic square foot requirements, there are also code requirements regarding exits, aisle width, etc.

You might also wish to look at the chemical storage and handling requirements especially when evaluating research labs and stockrooms that maintain large chemical inventories.

As indicated below, your local fire department can verify which of the fire codes applies to your facility.

Subject: Organic Chemistry Class Size

I  received this question in the divisional e-mailbox and Dr. Roslaniec 
said that  she would appreciate thoughts from the DCHAS membership.

From: Mary Roslaniec <roslaniecm**At_Symbol_Here**mjc.edu>

We are  re-evaluating our lab class size.  Historically, we have followed 
the ACS  guidelines.  Our General Chemistry and Introductory Chemistry 
courses  hold no more than 25 students per lab and our Organic Chemistry for 
Science  Majors class is generally below the 20 student limit.

Our GOB courses  span two semesters.  The first is general chemistry and 
the second is  organic/biochemistry combined; both are for the allied health 
majors.   The Office of Two Year Colleges advised the following:

�??To the best of  my knowledge, there are no specific recommendations for 
biochemistry labs  (certainly not in the Guidelines). However, you are 
considering a hybrid lab.  Because the student/educator ratio is a safety 
consideration in the  laboratory, I would go with the more stringent recommendations 
for organic  labs. In other words, treat the organic/biochemistry lab as an 
organic lab,  and limit the number of students to 20.

True, this course is �??organic  chemistry�??, however, it is at the GOB 
level.  Our courses are impacted so  we hesitate to lower the class size.  So, my 
question is, is the  recommendation for organic chemistry for the allied 
health majors really as  strict as the organic chemistry lab for science 
majors?

Thank you in  advance for your information.
