Polychlorinated Biphenyls (PCBs) were manufactured and used pre-1979 as coolants and lubricants in electrical equipment. The manufacture of PCBs was banned in the United States because they tend to build up in the environment. PCBs, once introduced into the environment, do not readily break down and can exist for long periods of time. They can travel via air currents and waterways. Deposition sites include soil, small organisms, fish and marine mammals, land and flying animals. PCBs have been found to cause cancer in animals.
Older fluorescent light ballasts have small capacitors that contain high concentrations of PCBs (unless the words "Contains No PCBs" appears on the ballast). These items are disposed of as hazardous waste. Call Bldg. Mgr. for collection and EHS for disposal.
