My indirect harm litmus test would fall along the lines of like an OSHA style philosophy of regulation, for example for any kind of ledges we generally require rigid hand railings. If someone got hurt falling off a ledge at my workplace sure I didn’t do anything to cause it, but I’d still be on the hook for their injury because I didn’t take the required steps to reasonably prevent unnecessary injury.
