Sighting rails should be installed and maintained to give equipment operators a visual clue while backing, unloading, and packing forage into the bunker.įigure 3. Cracked sidewalls should be repaired prior to use as these structural elements could fail if left unrepaired.įigure 2. Harvest Pre-Inspectionīunker silos should be inspected prior to harvest. For example, recent injury reports involving bunker silos include worker entanglement with a silage defacer (New York Department of Health, 2005) and a worker buried by collapsed silage at the face of a bunker silo (The Express, Lock Haven, PA, 2007). Even so, the most serious hazards seem associated with bunker silos because of the raised sidewalls. The size of bunkers, trenches, and piles can vary according to the size of the farm operation, and they all have some hazards in common. If forage is dumped on the ground or other hard surfaces into piles with no structural walls defining the silage mass, it is usually referenced as a drive-over pile silo. Horizontal silos that are cut into the earth with only the earth serving as sides are normally called trench silos. Bunker silos might have concrete or wooden post walls Most horizontal silos that are built above ground level with construction-grade material for sides are called bunker silos.įigure 1. These types of silos might also be referred to as trenches, pits, piles, or stacks. A horizontal silo is a storage system where forage is piled in relatively low (i.e., 6-20 feet), long piles that might or might not be contained by sidewalls (Tyson, 2006).
