4. How big a problem is this?
Put simply, the evidence gathered by Hycontrol and other organisations points to this being a huge problem globally. For example, based on an approximate number of 4,000 silos in the UK concrete industry, Hycontrol estimates (based on statistics recorded from a sample of 250 silos) that approximately 10,000 over-pressurisation events occur annually. Of course, these are not all of a destructive nature, but the scale of the problem far exceeds previous suspicions. Moreover, this problem is a global issue. A Google search will soon turn up stories of ruptured silos, blown filters, pollution, injuries and worse - and these are only the events that get reported.
This problem is real, it is substantial, and industries must address it to keep workers and the general public safe.
