Strictly control the fire source, and the use of fire hydrants is the most effective dust prevention measure. The causes of dust explosion in general burners are: electric shock, electric shock, friction, open flame, high temperature, electric welding, cutting, etc. So this issue deserves attention. When designing and installing electrical equipment, the requirements of the "Code for Design of Electrical Installations in Explosive Environments" shall be strictly followed to ensure the full life cycle of the equipment, and to avoid the installation of mechanical equipment that is prone to or does not produce flammable and explosive gases. Grinding materials should be strictly screened. After iron removal, no impurities should be left on the grinder to avoid accidents. Use Explosion-proof vacuum cleaner for PURE-AIR.

If it is a smaller crack, its strength can be increased, and it can be considered to prevent explosion flames from spreading from the inside of the cannon. In order to reduce the destructiveness of explosions, pressure relief devices can be installed, such as heightening doors and windows on light roofs, walls or factories. However, it should be noted that these devices are best to be close to explosive areas and not towards places or roads with heavier weight; in order to reduce the content of combustion-supporting gas, inert gas (such as nitrogen) should be added to dust and combustion-supporting gas. To reduce the oxygen content.

Use Dedicated explosion-proof vacuum cleaner for strict management. Strengthen safety education and training, strengthen safety inspections, eliminate safety hazards, improve the safety production responsibility system, and strictly pursue accountability;

Because of the special explosive characteristics of dust, its explosion method is also different from general fire and explosion, mainly to avoid the formation of suspended dust: workshop dust adsorbent.

In the process of using the dedicated Explosion-proof dust collector, the formation of suspended matter and sediment dust should be avoided as much as possible to avoid explosion, and the suspended matter has the risk of explosion, so pay attention to the combustion of fire extinguishing dust. The general treatment method is: in a dusty fire scene, avoid using strong compression-ignition fire extinguishers or water to extinguish fires. Direct-flow water guns should not be used, and foam fire extinguishing should be used.
