100 Mile House Fire-Rescue received a call to West Fraser Mill around 7:30 a.m. on Jan. 10.
Fire chief Roger Hollander says West Fraser mill staff initially extinguished most of the fire, but some of it made its way into the walls of the structure.
However, 100 Mile House firefighters were able to quickly locate and suppress the remainder fire in the walls.
108 Mile Ranch and Forest Grove volunteer fire departments were requested to attend for water support.
Hollander says the fire started as a result of welding taking place inside the building, which ignited the wall components.
“No one was injured at this incident and the mill was able to re-open shortly after.”
Fire-Rescue vehicles returned to the fire hall around 9 a.m.
