Richard is correct here on both counts... The real purpose of the PCB type oils was actually to be fire proof. GE invented at least one type, called Pyranol, think it was introduced in the 30's.., which is in some types of older capacitors. The fire danger comes not from the PCB oil, catching fire, (it is nominally fireproof or at least quite difficult to ignite) ...but other things or... a mixture of PCB and mineral oils..which is flammable.

At ultility eqpuipment suppliers URL is http://www.Electricinet.com... you can probably find a PCB test kit.. if you really want to check the stuff. Disposal could be problematical.. as there are only a couple of EPA aprroved sites and the operators know they have you and charge appropriately.
