“…The specific flame retardant used in the final formulation is proprietary, but is believed to be an aqueous halogenated compound. Adding inert or extinguishing materials to a potentially combustible dust is a recognized method to minimize or eliminate the fire and explosion hazards of a combustible dust described in the open literature [2,[11][12][13], reference books [14][15][16][17][18], and generally accepted industrial standards [19,20]. Historically, this method has been most widely used in coal mines where rock dust is spread on surfaces of the mine to inert coal dust.…”

“…However, differences in turbulence of the dust clouds and significant flame thicknesses probably play the main roles. Therefore, when using K St values for sizing of areas of explosion vents and Table 3, which shows explosibility data for dust generated in a wood-processing facility 19 (with K St determined in a 20-L spherical vessel according to ASTM E 1226-05). In the actual process, although the coarse dust was predominant, pockets of the fine dust were found in a dead-space in a process unit header.…”

The current paper gives a general overview of factors that can cause a dust explosion and the means by which such an event can be prevented and mitigated. Important explosibility parameters (e.g., maximum explosion pressure and standardized maximum rate of pressure rise) are described in terms of their relation to explosion causation, prevention and mitigation. Causation is further explained by means of the fire triangle and the explosion pentagon, and standard risk reduction measures are placed in a hierarchical arrangement incorporating inherent safety, passive engineered safety, active engineered safety, and procedural safety. The importance of safety culture and a safety management system approach are emphasized by reference to an industrial case study.

Abstract. The dust cloud is the main form of existence of combustible dust in the production area and together with the existence of effective ignition sources are the main causes of dust explosions in production processes. The minimum ignition temperature has an important role in the process of selecting the explosion-protected electrical equipment when performing the explosion risk assessment of combustible dusts. The heated surfaces are able to ignite the dust clouds that can form in process industry. The oil products usually contain hydrogen sulfide and thus on the pipe walls iron sulfides can form, which can be very dangerous from health and safety point of view. In order to study the influence of the pyrophoric sulfide over the minimum ignition temperature of combustible dusts for this work were performed several experiments on a residue collected from the oil pipes contaminated with commercially iron sulfide.
