PCBs, or polychlorinated biphenyls, have been used as a coolant and lubricating fluid in a variety of electrical products due to their good heat insulation properties. Hence they have historically been used in pole mounted and ground transformers, fluorescent lighting fixtures and equipment using hydraulic oils. PCBs are generally odorless and colorless and tend to persist in the environment. Aroclor is a common trade name of a PCB.
For new and relocating child care centers, this means that a NJDEP Licensed Site Remediation Professional will evaluate a site for the potential presence of PCBs, particularly in transformers in outdoor areas. Generally, if no spills or discharges or evident, no sampling is performed. For indoor evaluation, a NJDOH Licensed Indoor Environmental Consultant will determine if PCBs may be present in lighting fixtures and other equipment.
