One of the most disastrous dust explosions in history is the 1878 Great Mill Disaster in Minneapolis, US. Excessive flour milling caused a high concentrate of flour dust within the mill. One spark was all it took to ignite the airborne flour dust, resulting in a huge explosion that killed 14 workers.
All these steps have to be documented, put into an explosion protection document and shown to the authorities on demand. Measures in case of an accident. Especially the large fires and explosions in firms (e.g. explosions in a chemical company in Rotterdam in early 2011) indicate how important it is to have safe systems in place.
In case an air pipe is connected to the mill, a Ventex valve should be installed. It must be possible to detect the explosion thanks to a pressure sensor or a spark detector in order to stop the whole installation, and especially the valves in and out of the milling system.
Major dust explosions often follow the pattern of the 2008 Imperial Sugar refinery catastrophe the blast from a smaller, initial explosion disperses accumulated dust into a cloud, which ignites and fuels a powerful chain of secondary explosions. This model shows areas that normally do not contain high levels of dispersed dust, can still be at
