On September 10, 2015 Mark Hueftle, along with Allen Crawford from the Holdrege Cargill, had a session that covered grain safety. This was the 20th safety day camp held at the Kearney county fairgrounds with over 300 5th, 6th, 7th & 8th grade students attending from the Axtell, Wilcox/Hildreth & Minden schools.
We showed the students how a grain auger works and what would happen if they were to get an arm or leg in an auger by using a toy auger and a plastic soda straw. After letting them see this we used a visual example of how grain flows out of a grain bin and would place a small wooden cut out of a person on top of the grain. We would then let the grain flow out the bottom and would have the students count how long it would take the person become engulfed. On average it would take 5-7 seconds for him to become engulfed. We then showed a full body harness and how to wear one, how it works to hold someone up out of the grain and that this is the only way anyone should ever enter a grain bin.
At the end of the session there was a hands on demonstration to show how much they could pull if they were trying to pull someone out of a grain engulfment so they could see that they would never be able to pull someone out of grain if the person was waist deep in grain. It takes approximately 500-600 pounds of left to pull someone out and most students were able to lift under 150#.
