FREMONT -- Investigators will return to a machine shop in the Warm Springs area Friday to try and determine what may have started a three-alarm blaze Thursday afternoon.
The fire erupted about 1:45 p.m. at C and H Enterprises at 801 Boggs Avenue, fire officials said.
According to Fremont Fire Department spokesperson Steve Silva, the building will most likely be a "total rebuild" after crews arrived to find it engulfed in flames.
Silva said due to flammable and combustible liquids in the back of the building, firefighters briefly issued a shelter-in-place order for local businesses and residents, telling them to also turn off their ventilation systems to avoid any hazardous chemicals that could have traveled through the air.
There were no firefighter or civilian injuries reported, Silva added.
The shop offers welding and manufacturing for a variety of industries, according to the C and H website.
Fire crews remained at the scene for several hours to clean up and try to determine what may have been the cause of the fire, Silva said.
He said crews who first responded said the fire seemed to have originated in the southeast side of the building, near a warehouse, where plumes of black smoke and flames poured from the building.
