Two people were injured in an explosion at a chemical plant in the Chicago suburb of Alsip Friday morning, the Chicago Tribune reported.
The two people injured were taken to Christ Hospital in Oak Lawn. The severity of their injuries is not currently known. All other employees of the plant were accounted for.
According to NBC Chicago, police said the blast took place just before noon at Blue Island Phenol, which manufactures acetone and phenol. These chemicals are used in the manufacture of pharmaceuticals, cosmetics and herbicides.
Blue Island Phenol plant manager Bill Moffatt told the Associated Press there was a leak of "gas material," but it's not known if that triggered or ignited the fire.
Although surrounding streets have been closed, the area has not been evacuated.
