Ask a med spa owner about compliance and they'll talk about the medical board, supervision, the good-faith exam — the clinical regulation that dominates their attention. Almost none will mention OSHA, and that blind spot is exactly the problem. Your practice handles needles, sharps, and potential exposure to blood and bodily fluids every single day, which means OSHA's workplace-safety rules — the bloodborne pathogens standard chief among them — apply to you whether or not you've ever given them a thought. The citations OSHA issues to practices like yours are usually for gaps that are cheap to fix and expensive to ignore, and they surface at the worst time: an inspection, or an employee complaint.
This is general education for owners, not legal or compliance advice. Confirm your OSHA obligations with appropriate resources.
