How many square feet per student is recommended for class/laboratories?
The recommendation of NSTA and LSI is to have the lesser of 24 students per lab, and the design capacity of the room, or 55 sq. ft. per student for lecture/lab combo rooms and 45 sq. ft. per student for only lab rooms. The Laboratory Safety Institute has published a report on class sizes and lab accidents. “There’s No Safety In Numbers” summarizes the research in this area, state and federal regulations, and successful approaches to dealing with the problem.
