I would be almost certain they will have a fence or gate of some type...This has all the markings of an attractive nuisance lawsuit, if they don't.Other then the fence around the project, I can't see another gate at all. I'm just responding to the person that says there is one. I'm speculating in the event there is another one. But, to me it would be sensible to not leave all the mechanics in easy reach of non-authorized people (i.e. buzzy, but with a more bloody possible consequence.) However, not an evacuation stairway.
