To further reduce the risk of flour dust explosions, it is important to make physical modifications to the equipment and factory. For instance, factories are encouraged to improve their ventilation and install a dust extraction system. A major part of this is using a HEPA vacuum to efficiently clean up 99.8% of the combustible dust.

Laboratory experiments were performed in full scale test rigs that allowed triggering and monitoring coal system explosions on demand. Ignition events remaining within the coal pipe created only weak pressure rise, while ignition events within a simulated pulverizer volume created explosions exceeding 70 bar gage (1015 psig).
