A three-alarm fire that destroyed a Fremont business this afternoon was under control about an hour after firefighters arrived, fire officials said.
Crews responded to a report of a structure fire at C&H Enterprises, located at 801 Boggs Ave., at about 1:45 p.m., fire Capt. Steve Silva Said.
When firefighters arrived, they saw heavy smoke and flames and could not make their way into the structure, Silva said.
The roof of the building collapsed and crews battled from the tops of their fire engines' extended ladders, the captain said.
The business, which performs precision machining, welding and fabricating, has a placard posted to inform people there are combustible and flammable materials inside, Silva said.
Silva said workers safely evacuated the building and workers at other nearby businesses were asked to shelter in place as crews battled the fire.
The fire was under control within about an hour, but firefighters remained on the scene for hours afterwards, fire officials said.
Crews had yet to enter the structure as of 3:25 p.m. because the back wall was ready to collapse from the extensive damage, Silva said.
Once it is safe to enter the building, firefighters planned to put out residual small fires that were not yet extinguished, he said.
Alameda County and Hayward fire departments assisted with mutual aid throughout Fremont while crews battled the blaze, Silva said.
No injuries were reported in the fire, he said.
