Grain storage structures are an important part of grain production. It is important that bins are well maintained to deter pest and environmental elements such as moisture to affect grain quality. Moisture in grain can cause spoiling and clumping to occur which can lead to other dangerous conditions such as clogged unloading equipment, grain bridging, and grain avalanches. Harvesting and storing grain at the proper moisture content will lead to a better quality of grain and safer work conditions.

 

 

Grain entrapments and engulfments can occur in storage structures or transport vehicles because of unloading equipment or out of condition grain. When unloading equipment is powered on or unloading chutes are opened, the grain begins flowing down the channel. If a person is present, it can pull the individual further and further into the grain. The flowing grain from above collapses in surrounding and engulfing the individual. It only takes seconds for an individual to become entrapped to a point they cannot self-extricate. Very similarly, grain bridging and avalanches can lead to an engulfment as well. A grain bridge will occur when grain sticks together forming a false surface of grain with a void space below. If a person attempts to enter the grain bin, they can break through the surface, fall into the void space, and be covered by the surrounding grain. Grain avalanches occur when grain becomes stuck to the bin walls after unloading. Often an entrant will attempt to remove the stuck grain from the bin floor, and it will collapse on top of them. Before entering a grain bin or transport vehicle, consider referencing material such as OSHA CFR 1910.272 and ANSI/ASABE S624. Some key safety points from these documents are below:

 

An auger is an implement with helical flighting driven by various power sources to rotate the flighting around a center shaft and carry material from one end of the auger to the other. Auger conveyors are used throughout the grain production process. When grain is harvested, an auger transports it from the harvester to the truck for transporting. Other augers transport the grain from trucks into the grain bins where it will be dried and stored. Occasionally, during the drying process, grain can be moved between bins which is usually done by an electric auger. After the grain is dried, augers are also responsible for transporting it from the bins back to the trucks. Depending on the application and volume of grain that needs conveyed, multiple auger configurations or sizes may be used. As useful and helpful as this equipment can be, it also presents significant hazards if not used properly.

 

 

 

Entanglements are severely traumatic life threatening injuries that often result in broken bones, loss of limb, or even death. Properly guarded augers and Power Take Offs (PTOs) can be the difference between a close call and a fatality. Ensure that all shields and guards are securely fastened in place and in good condition. When working around equipment, following these safe practices:

When performing tasks of any kind, especially around grain, it is important to establish safe working areas. Work areas should only be entered by authorized and trained personnel with proper Personal Protective Equipment (PPE). During times of operation, it is helpful to have barriers and signage in place to deter others from entering without permission. Furthermore, these areas should be well maintained to minimize the likelihood of an incident occurring. Ways to create a safe work zone include the following:

Grain harvesting and handling can present many hazards and challenges for farm owners and employees. By promoting safety and ensuring equipment is well maintained we can complete tasks more efficiently and decrease the chance of an incident occurring.
