Method of determining whether or not PCB is contained

The disposal period for high-concentration PCB waste ended March 31, 2023.
Information on how to determine and dispose of high-concentration PCB waste that was posted during the disposal period for reference, but transformers and capacitors ended on March 31, 2022, and for ballasts and contaminants ended on March 31, 2022 and for ballasts and contaminants ended on March 31, 2023.
In the unlikely event that a high-concentration PCB waste is found, please contact the City of Yokohama, Resources and Waste Recycling Bureau Business Waste Management Section, Waste Reduction Promotion Section (Phone number: 045-671-2513).

　Transformers and capacitors used in high-voltage power receiving equipment installed in buildings, factories, etc. may contain PCBs.
　Investigate whether the equipment is stored in cubicles or warehouses for any discontinued equipment.
　When investigating equipment that is being powered, be sure to consult with the chief electrical engineer, as there is a risk of electric shock.

(a) Method of determining whether or not high-concentration PCB
　Some transformers and capacitors manufactured between 1957 and 1972 use high-concentration PCBs.
　Transformers, capacitors, etc. containing high-concentration PCBs can be identified by checking the nameplate attached to the device.
　Please contact each manufacturer based on the information on the nameplate, or refer to the Japan Electrical Manufacturers Association's website (outside site) to determine.

(b) Method of determining whether or not it is low concentration PCB
　Containers manufactured after 1991 (* 1) and transformers manufactured after 1994 (* 2, 3) do not contain PCBs.
　　（※1） Regarding capacitors made by Nichicon (external site), PCB contamination has been reported since 1991.
　　（※2） No replacement of insulating oil or maintenance related to insulating oil have not been performed.
　　（※3） For some equipment manufactured by Fuji Electric (external site), it is said that there is a possibility of PCB contamination in equipment shipped by 1994.
　Electrical equipment manufactured before the above manufacturing years may contain trace amounts of PCBs.
　Based on the information on the nameplate, contact each manufacturer, and if the possibility of a small amount of PCB contamination cannot be ruled out, we analyze the insulating oil of electrical equipment.
　Measure PCB concentration.

　When analyzing insulating oils of electrical equipment, if oil is collected unnecessarily, oil containing PCBs may leak to the outside and contaminate the surrounding environment.
　Ask a professional analytical supplier for PCB analysis of insulating oil.

　Business buildings (*) built before March 1977 may have ballasts that use PCBs.
　　（※） It covers common areas of apartments such as factories, buildings, condominiums and apartments, and warehouses.
　　　　　No home lighting fixtures use PCBs.
　　　　　Investigate buildings that have been used for business use in the past.

　By checking the contents of the lighting equipment label or the nameplate of the ballast, check whether it is a ballast using PCB.
　The lighting equipment in use may cause electric shock, so consult with an electric contractor or a specialized research company if possible.
　Companies wishing to introduce an electrician contractor should contact the Resources and Waste Recycling Bureau Business Waste Management Section (045-671-2513).
　Please contact me. We perform agency to electric construction industry association (Kanagawaken Denki Koji Industrial Association).

　PCB may have been used for ballasts manufactured between 1957 and 1972 (1972).
　Ballasts containing PCBs can be identified by checking the nameplate attached to the ballast.
　Please contact each manufacturer based on the information on the nameplate, or refer to the website (outside site) of the Japan Lighting Manufacturers Association to determine.

　In addition to transformers, capacitors, and ballasts, PCBs may also be used for electrical equipment such as X-ray generators, welders, elevator control panels manufactured and sold by 1993. There is.
　In addition, PCB oil, pollutants with PCB oil attached, pressure-sensitive copier paper, coating films, etc. must be properly treated according to the concentration.

For manufacturing equipment other than 13 companies, please contact the manufacturer directly.

Please contact the building's elevator maintenance company.

Please check the manufacturer of the condenser and contact us directly.

Judgment is made by concentration analysis determined for each property. If you have any questions about the need for analysis or analysis methods, please contact the City of Yokohama, Resources and Waste Recycling Bureau Waste Management Section, Waste Reduction Promotion Section (Phone number: 045-671-2513).
