The Hagley museum dealy with this problem years ago..it is really quite simple. We put brass washers on the floor to tell the visitors where the could be and put a kill switch controlled by a garage door opener so the interperter could stop everything if the someone violated the safety barrier. Also arranged the machine shop so that the feed side of the belts were protected y something,
