Details Polychlorinated biphenyls (PCBs) range in consistency from heavy oily liquids to waxy solids. Prior to 1979, PCBs were widely used in electrical equipment such as transformers, capacitors, switches, fluorescent lamp ballasts, electromagnets and voltage regulators. Their popularity derived from the fact that they do not readily burn or conduct, but rather only boil at high temperatures. They also do not readily react with other chemicals.As of July 2005 fluorescent bulbs, regardless of whether they contain PCBs, will be classed as hazardous waste under the Hazardous Waste Regulations, and will need to be disposed of accordingly.
