Dust explosions represent a serious hazard in the food and feed industry. Grain and flour dusts can form explosive clouds
and, because, explosions from such clouds have caused some of the worst industrial accidents, it is necessary to draw public
attention to this problem. This paper reviews some devastating explosions in flour mills and other facilities in grain handling
installations including an incident that took place in a bakery in Turin in 1785 which motivated research in this area;
analyzes conditions and causes of dust explosion in flour mills and associated facilities; and discusses explosion preventive
and protective measures to avoid many injuries and deaths and material losses. The explosion parameters for wheat flour and
rice flour dusts required for identifying the explosion hazards in wheat and rice flour mills and associated units and
designing suitable explosion preventive and protective measures determined using CSIR-CBRI 20-L Sphere, Godbert Greenwald
Furnace and Hartmann Apparatus are presented for specific samples alongwith literature data.
