In a ‘previous life’ I was Mill Manager in a large animal feed mill in Northern Ireland before I moved to England to look after several feed mills. Of course I knew all the plant guys well and therefore I was very sad to learn that one them, Gerry, had been killed. He was inside a raw material silo swinging on a rope trying to clean it when another operative diverted fresh material into the silo and literally drowned him. Over the years I have learnt of many other such fatalities within all types of silo, for example 26 of them occurred in the US alone in 2010, and that is why we at Primasonics designed a Safe, Remote & Effective means of cleaning silos which eliminates the need for manual entry.
