ABSTRACT


With the development of factory with dust filter, it leads to the increasing risks of the dust explosion. Therefore, the risk evaluation of dust explosion in factory with dust filters through evaluation methods are significant. Aiming at the factory with flammable dust, the characteristics and process of dust explosion accidents in factory with dust filters were described in the paper. The fire and explosion hazard index method and comprehensive evaluation method were applied to evaluate risk of a material factory with dust filters. According to the evaluation results, the corresponding measures and suggestions were put forward to prevent dust explosions and minimize the loss. Based on test results of the dusts characteristics in the factory, zone is classified bythe frequency and duration of an exposable atmosphere.
