Safely feeding out silage

Safety is a year-round requirement. Once it’s time for the silage to be fed out, the structure presents many dangers, which can easily be avoided by staying out of high-risk areas and remaining vigilant when working in, and around, silage structures.

Every Day

  • Never work in or near a silo, bunker or pile alone: bring a buddy to keep an eye on you.
  • Wear safety vests while working around silage and operating equipment.
  • Maintain communication and visibility with a buddy in a safe location when working on, or in, a silage structure.
  • Install guardrails on above-ground level walls.
  • Use equipment operating from the ground level to remove spoiled silage from the surface of bunkers and piles.

Prevent Falls

  • When on top of a silage pile, stand no closer to the feedout face than 6 feet.
  • Use caution when removing plastic, tires, tire sidewalls, and/or gravel bags from bunker silos and drive-over piles, especially near the walls and edge of the feedout face.
  • Always use caution when working on top of the silage bunker or pile.

Inspecting and Sampling Safely

  • Do not take core samples if the feedout face is more than 8 feet tall.
  • Never allow a person to ride in the bucket of a front-end loader to take samples from the silage feedout face.
  • When sampling silage, take samples from a loader bucket after it is moved to a safe distance from the feedout face.

Create a Safe Silage Face

  • Do not “pitch” spoiled silage. It is simply too dangerous to remove spoilage from the top of bunkers and piles. Only remove spoiled silage with equipment operated safely from ground level.
  • Use proper unloading techniques, which includes shaving silage down the feedout face.
  • Never dig the bucket into the bottom of the silage. This can create an overhang.
  • Never drive the unloader parallel to, or near the feedout face of an over-filled bunker or pile.

Maintain a Safe Distance

  • Never stand closer to the face than 3 times its height.
  • Never park vehicles or equipment near the feedout face.
  • Post warning signs to ensure visitors and bystanders observe these rules.

Silage Safety Zone: Never stand closer to the face than 3 times its height.
