that being said, yes, transformer oil is some pretty good stuff to burn due to the low contaminants in the oil. Just be careful of the "additives"
I don't know for sure, but I hear PCBs turn regulars into mutants that grow 3-4 extra arms out'a their forehead & 2-3 extra functional eyeballs looking out'a their butt, and start talking slow!
I don't know whats in today's transformer oil, but we used to haul transformers all thru '70s & '80's, all way from little itsy-bitsy to some really giant ones. We'd load in early '70s & shippers
might casually say something in idle talk, kinda in passing, over their shoulder "'ya might not want to get leaked oil on 'ya, try to wash it off in next couple of days"
By early '80s we signed that we received it, then they would hand us a big "Safety Package" with lots of 800#s to call if disaster struck, instructions on how to contain spills, inst. to wash up within very few minutes,etc etc.
By late '80s it got nearly to where my drivers had to sign & swear their life away along with their first born, have 800#s pasted on windshield to where they had to look past it just to watch the road, have shovels on board, nearly have a Zoot Suit onboard, be prepared to build & maintain a 30' **** around a spill of more than 2 drops, be educated & prepared in directing traffic, understand the workings of functional phones....
Then they had to get ready to give their soul to the Almighty, because if he didn't get it, the Government was!!!!
