Firefighters Saturday put out flames in the engineering building at Tustin High School.
The fire was reported at 1:10 P.M. at 1171 El Camino Real, the Orange County Fire Authority said on X, formerly Twitter.
The flames were put out “quickly,” fire officials said. That saved “a significant portion of the building from damage,” officials said.
No injuries were reported. The cause of the fire was under investigation.
