It's the beginning of a new semester here in the beleaguered California community colleges, and there is again an administrative push to over enroll students in chem labs.
So I am interested in the history of the 24-25 chem lab safety caps. Does anyone know why 24-25 has been deemed the upper safety limit and what evidence was used? Also, exactly what agencies and organizations (in the US and abroad) besides ACS and LSI recommend these caps?
For those of you in California, is it true that when a new chem lab is designed for a state-funded school that the lab design is based on 24 students? This is what I've heard, and architects seem to design California chem labs around this magic 24, but is it state-mandated?
Sincerely,
Marjorie Samples
Folsom Lake College, Folsom California
