WebPCBs can enter your body in three ways: by direct contact with the skin. PCBs pass easily through intact skin, so this is likely to be the main way they get into your body; by breathing in fumes, spray or droplets if PCB-containing equipment is being cut or heated; by swallowing PCBs if you eat, drink or smoke in the workplace.

Web• October 2007, responsibility for PCB disposal was transferred from OPPT to OSW Once production of PCBS was halted, a nationwide management and disposal program was established under TSCA that required labeling and maintenance of PCB containing equipment, market phase out requirements and strict disposal regulations. WebBefore 1979, PCBs were commonly used as insulators in electrical equipment, including fluorescent lamp ballasts and motor start capacitors. Although these ballasts and small capacitors may contain only relatively small amounts of PCBs, the PCBs are commonly in extremely high concentrations. PCB ballasts and small capacitors may be found in:
WebAug 21, 2015 · I was recently made aware of an issue regarding the oil used in the construction of certain high voltage capacitors made prior to the 1980's. These capacitors were filled with oil containing PCBs (Polychlorinated Biphenyls) - a known carcinogen and substance that is on the watch-list of several regulatory agencies including Environment … WebNepolin, EEC-18, and others. Equipment manufactured after 1979 usually does not contain PCBs. Most pre-1979 capacitors do contain PCBs, while many pre-1979 transformers do not. Transformers within buildings or vaults are more likely to contain PCBs. New equipment should be labeled "No PCBs." PCBs are clear, amber-colored, or dark oily …
WebIf in doubt, sample and analyze. PCBs were widely used and are still found in a variety of locations. Transformers can be pad-mounted, pole-top-mounted, in vaults, roof-mounted, etc. Transformers that use a liquid coolant, or “wet” transformers, may contain PCBs. Dry-type transformers that use air for cooling typically do not contain PCBs.
PCBs are a group of man-made organic chemicals consisting of carbon, hydrogen and chlorine atoms. The number of chlorine atoms and their location in a PCB molecule determine many of its physical and chemical properties.
