Polychlorinated biphenyls (pcb's) have been widely utilized as fire- resistant dielectric coolants in electrical equipment used in mining applications, including transformers, capacitors, electric motors, and electromagnets. In addition, pcb's have been used in hydraulic fluids and heat-transfer fluids and are present in many oil-filled transformers. The U.S. Environmental Protection Agency (EPA) recently banned the manufacture of pcb's and equipment using pcb's, and imposed strict requirements on the continued use and disposal of existing pcb equipment. This manual discusses the EPA requirements, suggests ways to decrease the risks resulting from continued use of pcb equipment, and surveys the non-pcb equipment that is available as replacements for the pcb electrical equipment presently used in mines.
