Huge fire burns Fremont metal plant, prompts chemical concerns

By the time fire crews arrived, flames had fully engulfed the building. More than 100 fire fighters fought the blaze. It took about an hour to get the fire under control. The building houses two companies, The Asko Group and Acu-Line. Asko provides metal finishing for the aerospace industry, and Acu-Line does metal etching. Both companies produce toxic waste.
