These chlorinated oils have a low degree of reactivity. They are not flammable, have high electrical resistance, good insulating properties and are very stable even when exposed to heat and pressure. All in all, they seemed to be the perfect oil for use in dielectric fluids, and as insulators for transformers and capacitors.
Transformers and capacitors Other electrical equipment including voltage regulators, switches, reclosers, bushings, and electromagnets Oil used in motors and hydraulic systems Old electrical devices or appliances containing PCB capacitors Fluorescent light ballasts Cable insulation Thermal insulation material including fiberglass, felt, foam, and cork Adhesives and tapes Oil-based paint Caulking Plastics Carbonless copy paper Floor finish
Uses for PCBs quickly expanded to include hydraulic fluids, casting wax, carbonless carbon paper, compressors, heat transfer systems, plasticizers, pigments, adhesives, liquid cooled electric motors, fluorescent light ballasts, and the list goes on. Fat soluble!!!!
Dark brown pigmentation of nails and skin, follicular accentuation, acne-form eruption, increased eye discharge, increased sweating at palms, and feeling of weakness were the most notable symptoms
