Some collaboration between the factory and the residential complexes might have made sense. Was the factory there first?
“Was the factory there first?”
The fertilizer plant was built in the 60s. Though I am guessing, I doubt a fertilizer plant would be built yards away from residential complexes. In the remote chance that those complexes were already there, it does not mean that people in 2013 were forced to live there. Everybody living 10 yards from the damn fertilizer plants had either accepted the risks or did not take personal responsibility of their own safety! Sorry to be blunt.
