: Thank you SO much for this information Bert! They are indeed made by Cornell
: Dubilier (sorry I forgot to mention that). My father is the one who
: procured them nearly 10 years ago. They do not have the date they were
: created on them. He stored them in my garage and has not taken
: responsibility for them.
: Recently I began packing up to move and found them again.
: I have had several people make offers to buy them. One person asked $300
: per capacitor! I don't want to sell them if they are harmful, though.
: Thank you again for giving me such extensive information. I will see
: where in my city I can take them to dispose of them.
: I am located in Santa Cruz, California.
: Thanks for all your help!
As long as the capacitors are intact, they are not a hazard. They could become a problem if the insulator seal fails or if the case is breached. They can even be used for their intended purpose subject to some restrictions. The following information may also help:
Regulations for capacitors in California state:
"Large PCB Capacitors (containing 1.36 kg or more of dielectric fluid) that are located in restricted areas (either a restricted-access electrical substation or a contained and restricted- access indoor installation) may continue to be used for their remaining lives. Large PCB Capacitors that are not located in restricted areas are prohibited. All small capacitors may continue to be used for their remaining lives.
No routine inspection requirements apply to capacitors unless they are stored for disposal, but it is good practice to inspect them annually for leaks.
Most capacitors cannot be sampled for analysis of PCB concentration. In most cases, the presence of PCBs can be determined directly from information on the capacitor or from the manufacturer. (All capacitors are assumed to contain PCBs unless the label or nameplate information, manufacturer's literature, or chemical analysis states that the capacitor does not contain PCBs.) The Environmental Staff can assist in this identification."
Good luck and best wishes,
