When two young men suffocated inside of a grain bin in Carroll County, Illinois in July of 2010, a local company used the tragedy as motivation to create a life-saving tool. The Great Wall of Rescue was constructed in Lanark, Illinois by Eastland Fabrication, LLC., a tool that can be used to rescue people who’ve become entrapped in grain bins. While it’s not the first concept of a rescue tube, the inventors say it’s the simplicity and affordability of it that makes it easier to use than other products on the market.
