If the Empire had OSHA, Darth Maul would still be alive today.
Handrail technology clearly was known in the Star Wars universe -- even Ewoks had handrail technology. Yet it's surprisingly absent from the more advanced civilizations in the Star Wars universe. As an example, there are numerous stairs on Tatooine with no handrails. And the Death Star, the pinnacle of Empire technology, had numerous bottomless pits without handrails, or any other safety equipment. Clearly the lack of an appropriate regulatory agency is to blame for the sad state of safety in the Start Wars universe.
OSHA requires the following for bottomless pits:
"Every pit and trapdoor floor opening, infrequently used, shall be guarded by a floor opening cover of standard strength and construction. While the cover is not in place, the pit or trap opening shall be constantly attended by someone or shall be protected on all exposed sides by removable standard railings."
Had proper safety equipment been in place at the bottomless pit where Darth Maul flung Obi Wan Kennobi over the side, Obi Wan would have remained in view of Darth Maul, or Obi Wan would have been spotted by the pit attendant, and Obi Wan would not have been able to engage in the sneak attack the lead to Darth Maul's untimely death.
