[Milsurplus] Oil filled capacitors and PCBs in our equipment

[sbjohnston at aol.com]

I only rarely see capacitors marked as "containing PCB".  These are usually quite new caps, not the ones in vintage gear'
I rely on the trade names to decide if a capacitor or transformer contains PCB.  You can see a list of some of these names at
https://en.wikipedia.org/wiki/Polychlorinated_biphenyl
I've done a number of projects to replace PCB capacitors at broadcast transmitter sites.  The trade names I remember seeing most frequently were 

Pyranol
AskarelDykanolClorinol 
Santotherm

I don't have much concern about occasionally touching dielectric oils containing PCB.  I just clean up the area carefully and wash my hands thoroughly.  But I worry very much about having PCB around if there is a significant chance of fire.  In a fire, I understand that PCB can change into other very toxic chemicals that we do not want to breathe.
