The OSHA Laboratory Standard, found at 29 CFR 1910.1450, sets forth, as law, rules for EMPLOYERS engaged in laboratory use of hazardous chemicals (definition coming up).  Their definition of lab use is not completely intuitive, and must be carefully considered before a particular workplace may be considered as involving laboratory use.

Quite a bit of the chemical use and handling here at the University, even in academic departments, is NOT laboratory use, and is therefore subject to a different set of rules.  Maintenance shops, glassblowing, Stores, teaching prep and demo facilities, instrumentation facilities....  (PS "chemicals" includes formulations such as paints, inks, cleaning agents, solder and flux, pump oil.....)
