Two employees were in the building at the time, but were able to get out on their own safey.
The New Berlin Fire Department assistant chief said the City of Waukesha Hazmat Team was called out because the company does chrome and metal plating.
"They have a lot chemicals, tens of thousands of gallons of hazardous chemicals in here. We did have quite a large smoke plume so that caused us to initiate shutting down all the businesses in this area West of this building. We evacuated from 166th Street, the corner of the building on, all the way to Calhoun Road,” New Berlin Assistant Fire Chief Ross Gscheidmeier said.
The Wisconsin Department of Natural Resources (DNR) is investigating because of the chemicals that spilled as a result of the fire.
