Farm Safety – Grain Handling Equipment

Harvest season is right around the corner.  As we all know this time of year can be very busy with many different activities happening at once.  Try to keep safety in mind especially around grain handling equipment.  There are many potential hazards to consider when handling grain, such as equipment entanglement, grain entrapment and engulfment, dust explosions, among others.

This fall, lower your risk of injury by using a safety checklist.


  • Check that all exposed moving machinery parts have guards, shields, or cages installed and in good condition to prevent entanglement, including auger flighting, conveyers, belts, and power-take-off (PTO) components.
  • Don’t wear loose or baggy clothing, tie back hair, and remove dangling drawstrings and jewelry that could get pulled into moving parts.
  • Lock-out the power to augers, conveyers, belts, and PTO components before performing maintenance or replacing parts so they can’t be accidentally turned on.
  • Steer clear of flowing grain, which can trap a person knee-deep in a matter of a few seconds and can completely submerge them in less than 20 seconds.
  • Work from outside of the bin whenever possible and use safe bin entry procedures including the buddy system when a bin must be entered.
  • Check that everyone knows how to de-energize grain loading and unloading equipment and lock-out the power sources so that grain moving equipment can’t be turned on while someone is inside of a bin.
  • Use hazard signage and teach kids and unexperienced people to stay out of stored grain, including bins, piles, and grain transport vehicles.
  • Keep the grain vacuum nozzle away from the area below your feet and keep an eye on the angle of the grain surface as you are removing grain. To prevent grain flow, the grain angle should be less than the grain’s angle of repose, which is around 21 degrees for corn and 23 degrees for soybeans.
  • Check that fire extinguishers are easily accessible at the grain storage site. Grain handling facilities naturally collect dust which can lead to explosions given the right conditions.
  • Clean off dust accumulated in grain legs and elevators and service bearings, belts, and motors regularly. Just a paper-thick layer of dust is combustible in a confined space and overheated equipment parts or static electricity can be an ignition source.
  • Recheck combine settings as grain condition changes to reduce kernel damage and collection of fines and trash. Dry conditions across Iowa may cause overly dry and brittle grain or uneven conditions across farms, making regular combine adjustments important.
  • If excess fines and broken kernels are collected, either clean the grain before it goes into the bin or core the bin multiple times during filling to remove fines accumulated in the center of the bin. Removing the center core of fines and broken grain will improve aeration in the bin and reduce the risk of grain spoilage and unloading issues down the road.
