I worked in a Power Plant and we had a tank in the middle of the building covered in Asbestos, before they even broke the surface of the covering , they sealed that whole area from top to bottom, plastic sheeting negative air pumps the whole lot.
It cost a bundle for a company to come in and remove that shit. I cannot imagine what it would cost to clean that factory and surrounding area, I bet know one will touch it the factory is like chernobyl sitting there Killing all and sundry.
Good report and pics,
