A fire at Hibbing Community College only damaged a truck, and firefighters say it's all thanks to one little sprinkler.
The northern Minnesota fire department posted to Facebook, saying the fire started early Saturday morning.
The Hibbing Fire Department got to the college around 4:30 a.m. and initially didn't see the fire. Then they spotted some smoke coming from a garage.
When officials entered, they found a single semitruck had caught on fire, but it was being contained by a single sprinkler overhead.
Firefighters took care of the rest and ventilated the building.
While the truck has been deemed a total loss, the rest of the building only suffered smoke and minor water damage.
"If the building had not contained a properly serviced and maintained sprinkler system, the damages could have exceeded 1 million dollars and could have resulted in significant delays in college classes resuming," the fire department said in a Facebook post.
There was no one inside the building at the time, and no one was injured in the fire.
Officials expect damages to be $48,000 for the truck and $5,000 to clean up the building.
