I will admit that I am wondering just what the lessons learned list will be like safety-wise once they've finished up the season. I can't imagine that hydraulic fluid is that good for you, but that's not the bit that necessarily raises an eyebrow.

(Okay, yes, it does raise an eyebrow...but there is something bigger...)

I don't know if this is in the recaps, but one of the robot's fists popped off during a fight. In the in-show interviews, Mark Setrakian does say that they're hitting each other with the force of a sledgehammer blow. So, with the operators unprotected, what happens if something smaller gets knocked off, heading upwards? How much danger can shrapnel do here?
