Officials say that the fire at Beale Air Force Base is out but still smoldering as of Tuesday morning.
The building is a total loss, officials note.
The fire originally started around 2:30 p.m. Monday at the Civil Engineering Squadron Building. Normally, 200 people would be inside, but thanks to the holiday, only one person was there.
That person was able to get out safely, Beale officials note.
Firefighters from the base, along with firefighters from Linda and Wheatland, got the fire under control. Full containment was reached by 10 p.m. However, the 44,000 square foot building was severely damaged.
One Beale firefighter sustained minor injuries when an object fell on his head. He was taken to the hospital.
The cost of the damage is estimated to be more than $10 million, with the cause of the blaze is still under investigation.
Crews have been disconnecting power to the building and are figuring out a way to bring it down.
Beale’s civil engineers help maintain roads and bridges. The 2-story building, one of the bigger structures on the base, housed plumbing and electrical items.
