An early morning run for members of the Grand Forks Fire Department. Five engine companies and a ladder truck rolled around 3:30 a.m. to the Wood Products building on South 46^th Street.

When crews arrived they discovered smoke in a boiler room. Hot embers in a dust hopper used for fueling the boiler activated the sprinkler system which extinguished the flames. Firefighters working the scene also knocked down some small embers. No structural damage was reported. Crews were on the scene for about two hours monitoring for hot spots. The cause is under investigation.
