I weighed in before but let me add this:

Be very clear what purpose really is of the Code of Conduct and any Safety Officers before going down that road. Be assured that the ONLY thing a CoC can be in such settings is codified reasons for- and semi-legal agreement as to under what terms a guest be ejected from an event and the ONLY thing the SO's can be is initial enforcement arm of that action and.or any lesser actions leading up to that point.

Anything more is willful thinking leavened by the occasional bit of serendipity because, aside from the above, it's shelfware insofar as the bulk of attendees are concerned. And the ones who do read it either don't need it or are the sort that would take advantage of it later.
