Sep 28, 2020 Dust can cause dermatitis and allergic reactions. More seriously, dust particles can become embedded in the lungs and can cause respiratory problems like asthma and lung cancer. In addition, many solid food ingredients are combustible, including sugar, starch, spices, proteins and flour. Lastly, food particles can damage other food products

An initial (primary) explosion in processing equipment, or in an area where fugitive dust has accumulated, may dislodge more accumulated dust into the air, or damage a containment system such as a duct, vessel or collector. As a result, if ignited, the additional dust into the air may cause one or more secondary explosions
