Countering Catastrophe: New Solutions for Managing and Preventing Silo Explosions
The world was shocked by a catastrophic silo explosion in a Savannah, Georgia sugar plant in 2008. Preventing such events from happening again begins with an increased understanding about how dust explosions occur and what practices should be part of an overall strategy for reducing the opportunity for them to occur and mitigating the damage they cause if they do. An important component of managing and preventing silo explosions is the storage structure itself. This paper provides an introduction to how dust explosions occur in bulk-storage environments, helping readers understand the difference between deflagrations and detonations, and pointing out some indirect causes of ignition, such as self-heating product. It also highlights some benefits the Domesilo offers over traditional storage solutions as part of a comprehensive strategy for explosion prevention. This paper was written to a professional, non-technical audience.
