The area around grain bins is dangerous when high-voltage power lines are present, because of the portable augers and dump trucks that are often used to move grain. The best way to avoid problems is to put bins a safe distance from any overhead power lines, as shown below:

The National Electrical Safety Code sets minimum clearances for power lines near grain bins. Vertical clearances depend on the height of the bin and the distance from the side of the bin, as shown below. An area where portable augers will not be present can be considered a Non-Loading Side.
