The smaller dust gets, the surface area per unit mass increases, resulting in the growth of the contact area with air and subsequent acceleration of oxidation speed. It helps to increase the possibility of formation and maintenance of dust clouds and to rise risks of dust explosion by reducing ignition energy. Loxoprofen acid dust used as a material for anti-inflammatory drugs and painkillers by pharmaceutical companies contains little moisture, and is a highly explosive material since more than 75% of the dust has an average size of 10 ㎛ or smaller as fine organic dust and has very small MIE (Minimum Ignition Energy) with 1 to 3 mj on average compared to other dust materials. An experiment has been conducted to compare loxoprofen acid dust with other explosive dust materials to prove explosion risks of the loxoprofen acid dust, using a control case. In this study, fundamental solution and improvement measures against explosion risks discovered have spread to relevant companies to get rid of explosion risk factors in advance through improvement of facilities. It has been confirmed that this thesis study can be used as basic data to reinforce safety standards for prevention of fire ignited by loxoprofen acid dust in the future.
