The four-alarm fire broke out at around 7:00 a.m. Monday at the Chemtool manufacturing plant.
A full-scale evacuation is underway within a mile of the facility, which includes a high school.
Huge plumes of thick, black smoke can be seen for at least 25 miles away as flames continue to erupt.
It’s still unclear what caused the fire.
There is no word on injuries.
