Investigators are trying to figure out what started an afternoon fire at a grain elevator.
The fire started around noon in Gilbert at the key cooperative building.
Crews had to call in the Ames ladder truck to help reach the fire.
The Gilbert Fire Chief said sometimes it is important to call for help.
“With grain elevators there is always a concern for explosions from the grain dust. This was likely a spontaneous combustion inside the bin,” said John Berg, Gilbert Fire Chief.
The fire is believed to be the result of spontaneous combustion as the bin had no electrical or moving equipment inside it.
