COLUMBUS, Ohio – As corn silage harvest comes to a close and grain harvest nears, growers need to be aware of safety precautions to prevent grain engulfments.
According to safety experts from Ohio State University’s College of Food, Agricultural, and Environmental Sciences, the issue is of particular concern this year as higher moisture levels in some crops could lead to more out-of-condition grain at storage time.
That can increase the chance for grain bin disruptions and potential engulfments, said Andrew “Dewey” Mann, safety research associate for Ohio State University Extension.
“The way things are looking right now we’re hearing from some growers that moisture levels are at 28-32 percent,” Mann said. “Some growers have started harvesting already, and they have to get that grain harvest down to safe storage moisture levels.
“Corn needs to be at safe storage moisture of about 15 percent, or cooled quickly to reduce biological activity (spoiling grain).”
This lessens the potential for grain bin engulfments because out-of-condition or spoiled grain can impact the flow of grain in the bin, Mann said.
Grain bin engulfments can occur when growers enter the grain bin to determine why grain flow has stopped or slowed, he said.
“Many anecdotal reports and case studies of grain engulfments include farmers who, after finding the flow of grain stopped, will enter the grain bin alone with the auger continuing to run and begin to poke at the lodged grain from above with a long pipe, bar or board,” Mann said.
But when the pipe breaks through the caked grain over the grain intake, grain flows and the farmer is immediately buried in the grain.
In fact, in 2010, there were 51 grain entrapments on farms and commercial facilities nationwide, half of which were fatal, he said.
Already in Ohio, there have been two fatalities this year alone involving grain bins and silos, Mann said.
“Even experienced growers can find themselves engulfed in grain bins and silos,” he said, noting that the two fatalities associated with grain bins and silos this year in Ohio were both males over 65.
“Most growers have probably entered that grain bin many times before, but each year is a new product as a result of a new growing season,” Mann said.
“Even though you’ve been in that grain bin before doesn’t mean that the conditions are similar to those you’ve encountered before.
“The issue is that when the grain stops flowing, that’s the point where people often stop thinking about safety and focus on the need to get the product out. They just don’t anticipate how quickly the grain will start flowing.” Grim statistics. From 2001-2010, Ohio reported 14 farm-related deaths associated with grain bins and silos, he said.
