Silo safety is a pressing concern that could pose significant damage if left unchecked. It doesn’t help that OSHA hasn’t issued standard and precise requirements for determining a silo’s structural integrity. Given their tremendous sizes, a collapsed silo can result in a horrific loss of human lives, affect production, and cease operations.
Such situations can be avoided by having a silo inspected by a trained professional engineer. Visual examination of the silo walls from the ground or surrounding structures using binoculars and up-close observations of specific places on the external surface of the silo walls are all part of a complete silo inspection.
Silo Inspections You Can Make Regularly
While professional inspections are advised every 1 to 5 years unless there are structural or operational issues that demand more frequent inspections, there are several areas that you can and should examine in-house regularly. Here are some examples:
Roofs are an essential component of silo construction. Look for evidence of cracking or peeling in the roofing coating during an in-house examination. Aside from the safety concern, leaking roofs can contaminate stored materials, lowering product quality.
2. Exterior Finishes
Although concrete is a better material for storage silo construction, regular loading and unloading activities might cause structural difficulties over time. Stress is indicated by cracks in silo walls, linings, roofs, and foundations.
Horizontal, vertical, or diagonal cracking in concrete walls may indicate delamination or separating the concrete into layers. Delamination of silo walls is a significant problem that can lead to wall failure or collapse and should be treated quickly by a competent silo repair firm. During a visual check, look for corrosion or buckling of metal silo components, exposed rebar, or other degradation such as spalling.
3. Roof Support and Pockets
Internal roof beams that sit inside beam pockets support the roof slab. To prevent roof collapse, these components must be examined and serviced regularly. Spalling concrete around the beam pocket shows that the concrete is deteriorating. If this trend continues, the pocket will not hold the roof beam, resulting in collapse.
4. Issues With Material Flow Rate
Material flow issues might develop as a consequence of faulty design for the stored materials or material build-up. Reduced output is a definite indicator of material flow difficulties. If not treated promptly, this can increase strain on silo walls, causing bending and structural collapse. To accurately identify the reasons for material flow problems, it is critical to understand the specifics of silo architecture.
While regular in-house inspections are essential, it is also critical to recognize their limitations. Structural engineers or silo specialists are trained to identify delicate or otherwise normal-looking defects that could later pose significant hazards. While damaged silos may occasionally be rebuilt and stored material recovered, corporations are sometimes faced with extra expenditures following a breakdown in the form of cleaning, potential environmental damage, injury, and even loss of life.
