A fire broke out at the planer at Skeena Sawmills just after midnight.
A patrolling security officer noticed the planer stacker engulfed in flames, and called 9-1-1.
The Terrace Fire Department rushed to respond with three trucks and 16 firefighters.
They battled the flames and extinguished the fire in approximately one hour, according to a recent press release.
The Thornhill Fire Department was requested to attend with their aerial unit, but in the end the unit was not required.
Production supervisor Ravi Sandhu says the fire is out and electricians are now investigating.
No one was on shift at the planer at the time, just a clean up crew, and no one was injured.
