The Knoxville Rural Fire Department will have a new tool at their disposal in the near future. 3M in Knoxville is donating a truck in their inventory to the fire department. Rural Chief Kenny Thompson tells KNIA/KRLS News that the truck will be useful because it had a foam system. That allows firefighters to distribute thick foam over a fire, smothering it. Thompson says that would be helpful in the event of something like a hay bale fire.
