An ammonia leak in Itasca led to the evacuation of buildings downwind of the ITW building, located at 1349 Bryn Mawr in the northwestern suburb.
Employees noticed the leaking tank and called officials at 9:22 a.m. HAZMAT crews responded.
There are no reports of injuries or illness. The evacuated buildings are all businesses, not residential, officials said.
