nonPCBs

NonPCBs are materials and products that do not contain polychlorinated biphenyls (PCBs) above regulatory thresholds. The term is commonly used in environmental management, waste classification, and industry to identify fluids or equipment that can be treated as nonPCBs under applicable rules.

Background: PCBs were widely used as dielectric fluids and heat-transfer fluids in electrical equipment and other industrial products until bans and restrictions were implemented beginning in the 1970s and 1980s. PCBs are persistent in the environment, bioaccumulate, and can pose health risks. Regulatory frameworks in many jurisdictions require the identification, removal, and safe disposal of PCB-containing materials. When PCBs are present only at trace levels below regulatory thresholds, equipment or materials may be labeled nonPCBs for regulatory purposes.

Applications and examples: In practice, nonPCBs describes transformer oils, insulating fluids, and hydraulic fluids that meet the nonPCBs standard. Replacements used in industry include mineral oil, synthetic esters, and polyalphaolefin-based fluids. The designation may also apply to electrical equipment marketed as free of PCBs or with PCB concentrations below regulatory thresholds.

Regulatory and classification notes: Classification as nonPCBs helps determine handling, storage, and disposal requirements. Thresholds vary by jurisdiction, but a common approach treats materials with PCBs below tens of parts per million as nonPCBs. Documentation and testing are often required to verify PCB content and compliance.

Limitations: The nonPCBs designation does not imply absence of all contaminants, nor does it guarantee long-term safety; ongoing monitoring and proper recycling remain essential.
