RE: Transformer Oil tests for 40PPM for PCB's - Should I be concerned? ? ? (fwd)

Thanks. I guess after researching PCB's on the web, reading all these
horror stories, all the severely strict regulations and health hazards on
EPA, and other websites, its enough to make you nervous.
Anyways, they recommend cleaning up spills using a solvent such as mineral
spirits or kerosene. So I'll just give a thorough washing of my trunk with
that and dispose of the rags properly.
Transformers that were originally filled with PCB's were done so to
reduce the danger of fire in case of a catastrophic fault. Your
transformer has apparently been flushed and refilled with some type of
solvent-like flammable insulating oil. While some residual PCB's remain,
the current level (~40 PPM), while measurable, shouldn't represent a
hazard to either you or the environment.
At 40 PPM, your contaminated oil is still below the threshold (50 PPM)
the EPA uses for requiring regulated disposal. Even if your transformer
held 5 gallons of oil, the total residual PCB's would amount to less
than 0.03 Oz. Many hobbyists have capacitors with ounces (or even
pounds) of PCB's sitting on shelves or junk boxes. PCB's are virtually
inert (a property which makes their disposal problematic). Relax - your
small spill should present no risk to you, the environment, or your
vehicle. Shampoo your trunk to clean out any oily residue and (more
importantly) give you some peace of mind.
