A fire erupting in a shed at Sierra Pacific Industries' Quincy sawmill destroyed one building and damaged the plant's electrical system, temporarily closing all operations.
The flames reported at 12:30 p.m. Wednesday were in a metal building between the sawmill's co-generation plant and a series of large Pacific Gas & Electric Co. transformers, said Robbie Cassou, Quincy fire chief.
Firefighters contained the damage to the shed, which was gutted by fire, Cassou said.
The fire, which caused hourlong power outages throughout the Quincy area, left the sawmill without electricity.
Kristapher Gunn, 31, a Quincy volunteer firefighter, was taken to Plumas District Hospital for treatment of injuries to his right foot resulting from a fall from a ladder while operating a hose line, Cassou said.
The cause of the fire is under investigation.
