Dan, all,

I would have to agree with you here. I'm sure a
"basically" petroleum based fluid would burn quite
nicely with a far greater concentration of PCB con-
taminant than 50 PPM! 50 PPM PCB is the maximum
EPA contamination level allowed and I'm sure 1/20,000th
part PCB would not impede the combustible character-
sitics of petroleum by any perceivable amount, nor would
much higher concentrations of PCB, say 40X more PCB
concentration, or 1/500th part. PCB itself is not combustible,
but I don't think it's going to have a "halon" effect when mixed
in small concentrations with petroleum based liquids, either.

The "burn test" is a very poor indicator of PCBs.  Mixtures that contain
non-PCB oil mixed with PCBs still tend to burn.  I have had about 4
transformers i've tested that were negative on the burn-test, but positive
on the chemical test.
