"Old" shop equipment may have PCB-containing components such as capacitors and transformers.  Production of PCBs was banned in the United States in1979, but "in-stock" PCB-containing components may have been installed in shop equipment manufactured after 1979.  See the US EPA web site about disposal of PCB-containing items: http://www.epa.gov/epawaste/hazard/tsd/pcbs/index.htm

California regulations may be more stringent.  If your institution has an environmental compliance officer, I suggest a consultation.
