The dangers are real in that place, I'd be careful taking a young one around it. I've personally fallen through the floor in a few rooms, a few times! Asbestos is also all over the place in the basement and some scattered around the room next to the silo, I'd recommend wearing masks if only to avoid the airbourne nasties in there from the damp if you plan on avoiding the asbestos.
I've spent around 17-18 hours in the place across 4 visits, I know how dangerous some of the rooms are buddy.
