To assist in the identification of PCB transformers the effective use of signs and labeling should be instituted. While labeling of PCB transformers is required (using the mark “ML”), 10 additional signs and labels should be placed in areas near the location of a PCB transformers).

Standard PCB, no PCBs, and non-PCB labels are available from EHSO CAUTION: Aged labels on electrical equipment may not accurately represent the PCB concentration of the equipment's contents. For example, sealed transformers labeled as containing non-PCB oil may become contaminated with PCBs during servicing.

Even though PCB’s were effectively banned in the 70’s, many transformers and simpler electrical equipment still contain this deadly material. Discontinued the manufacture of distribution transformers in 1975. All Allis-Chalmers mineral-oil filled transformers comply with the PCB non- contaminated guidelines. Central-Moloney Transformer Division of Colt Industries C-M will certify that any transformer manufactured after 1962 is PCB non-contaminated. Serial Number Interpretation Standard PCB, no PCBs, and non-PCB labels are available from EHSO CAUTION: Aged labels on electrical equipment may not accurately represent the PCB concentration of the equipment's contents. For example, sealed transformers labeled as containing non-PCB oil may become contaminated with PCBs during servicing.

Transformer test methods. Polychlorinated biphenyl (PCB) analysis. PCB’s where realised in the 1970’s during the oil crises to bulk up the transformer oils. Due to the high toxicity of PCB’s it is now legislation to know the PCB content of your transformer oil. Dissolved gas analysis (DGA)

For example, sealed transformers labeled as containing non-PCB oil may become contaminated with PCBs during servicing. (b) As of October 1, 1978, each transport vehicle loaded with PCB Containers that contain more than 45 kg (99.4 lbs.) of liquid PCBs at concentrations of ≥50 ppm or with one or more PCB Transformers shall be marked on each end and each side with the M L mark as described in § 761.45 (a). PCB concentration assumptions applicable to transformers containing 1.36 kilograms (3 lbs.) or more of fluid other than mineral oil, see §761.2. For provisions permitting reclassification of electrical equipment, including PCB Transformers, containing >500 ppm PCBs to PCB-Contaminated Electrical Equipment, see § 761.30(a) and (h).
