No OSHA Compliance: Averted, even in the absence of anything resembling an OSHA.  Skilled labor is not cheap, and liability payouts are even less cheap.  Even averted in the places intended primarily to be occupied by robots and only rarely to ever be entered by actual people.  (True, they omit a few of the safety features and warnings seen on Earth – but that’s because those are the ones principally designed to protect from chronic stupidity, not accident.  Yes, while stupidity doesn’t create liability, it’s still expensive for other reasons – but that’s an avoidable problem if you’re ruthless enough about firing all stupid people.)
