shock hazard. Some capacitors retain deadly amounts of voltage even when disconnected. Oil filled electric equipment manufactured prior to 1980 must be assumed to contain PCBs unless analyzed by a lab. After 1979 manufacturers began marking the
PCBs in Fluorescent Light Ballasts1
The use of PCBs in capacitors, including those contained in FLBs, is authorized by 40 CFR 761.30(l). There are certain restrictions on the use of PCB large high voltage capacitors and PCB large low voltage capacitors, but 40 CFR 761.30(l) allows for unrestricted use of the small capacitors found in FLBs while they are intact.
How to Recycle Capacitors
Recycling capacitors is a way to keep old aluminum, steel or iron out of the waste stream and turn it into new uses. Although most local recycling pickups don''t take capacitors, many metal recyclers do. Because capacitors are meant to store power, you''ll have to follow safety steps when removing one from the electronic device that contained it.
