It's on page 6 of the current CPT Guidelines

Laboratories should be suitable for instruction in the chemical sciences
and must meet applicable government regulations. Properly
functioning fume hoods, safety showers, eyewashes, first aid kits, and
fire extinguishers must be readily available. Construction or renovation
of laboratory facilities must conform to the regulations of the
Occupational Safety and Health Administration (OSHA) and national
norms. The number of students supervised by a faculty member or by
a teaching assistant should not exceed 25.
Many laboratories require
smaller numbers for safe and effective instruction.

I thought I remembered seeing a recommendation from the Committee on Chemical Safety (CCS) for the safe number of students in college chemistry laboratories, but I can’t locate it. Would someone please tell me where to find this?
