As far as I know, all synthetic turbine oils contain some sort of organophosphate. (I was told the stuff is there to stabilize the oil, but I have also seen it cited as an "anti-wear compound." Any organophosphate compound may be called TCP, while it may be that it's not literally TCP, and all organophosphates are known neurotoxins.
What brand of oil is your company using, speedrestriction?
Here's an article that shows there's probably not a problem:

That would be great news, except that it's directly contradicted by many other articles, such as this one:

There was something similar that went on with the oil used in electrical transformers in the States. (Those round cans you see on power poles, for example, are oil-filled transformers.) Sometime in the Seventies it was finally agreed that the oil was highly toxic due to PCB content. Before then there was no real consensus that the stuff could be hazardous.
Profit-driven industries usually do not go looking for problems. Not that industrialists want to poison people, it is simply that they mainly want to make a buck.
Some people go too far trying to make a buck, as with a tragedy in Spain when people may have consumed organophosphates:
