Flour in most of bakeries are now is done through bulk handling where wheat flour are stored in large silos . Conveying is done through pneumatic conveyors its in these pipelines that explosion might happens . Filters bags are also used in these bulk handling of flour which are also explosion zone in bakery .Electrostatic arrestors has to be installed on these areas to prevent explosion .
Similarly sugar grinding are done in house for most of the bakery plants . Sugar when grinded becomes charged and with given atmosphere can result in explosion . Electrostatic arrestors and earth should be provided to sugar grinder as well as the filter bag stations which are installed to prevent dust to disperse in surrounding .
