The continued development of human society, from the technical and economic point of view, has led to the need for the increasingly widespread use in the various existing industrial branches of chemical substances and compounds in the form of combustible dust and dust. The processing, handling and storage of these pulverized substances often leads to the emergence of complex explosive mixtures whose explosiveness characteristics cannot be assimilated with the data available in the literature. In places where the p...

A potentially explosive atmosphere exists when a mixture of air, gases, vapours, mists or dust combines in a way that can ignite under certain operating conditions. Hydrogen is the special gas in this context. Those who have knowledge of the properties and flammability of hydrogen will recognize that hazards due to explosive atmospheres must be assessed more and more frequently as the element is utilized, and, if necessary, appropriate protective measures must be taken. In this kind of atmosphere, special attentio...

Materials and technical equipment, especially their external parts, are inherently subjected to the electrification process during their use. The electrification process of the materials and external parts of the equipment, especially the non-conductive ones, is responsible for the generation, through specific mechanisms, of significant amounts of electrostatic charges. The electrostatic charges generated as a result of the electrification process on the materials and external parts of the technical equipment used...

Many processes involving dusts, suspended or accumulated, have the potential to lead to fire, explosion or decomposition in the presence of oxygen and an ignition source. The risk of dust explosions increases as more and more products take the form of dusts or require the use of dusts during manufacture. In spite of extensive research and development to prevent and mitigate dust explosions in the process industries, this phenomenon continues to represent a constant hazard to industries including manufacturing, usi...

The processing, transport and storage of flammable materials in the form of dust generates an explosion risk due to the possibility of initiating potentially explosive atmospheres created by dust suspended in air with various ignition sources, some of which may be their own installations. As explosions can cause human casualties and severe property damage, the explosion risk assessment and the application of appropriate measures by manufacturers and users of installations to prevent the ignition of explosive atmos...

The electrification process of the materials and technical equipment-s, especially the external parts of them, frequently occur during their use, being sometimes an intrinsic process, such as for example flowing of a flammable liquid through a pipe. The electrification process of materials and technical equipment-s is responsible for generating, through specific mechanisms, significant quantities of electrostatic charges. The presence of electrostatic charges on materials and technical equipment-s, used in areas w...

Because, in most cases, dust explosions cause significant damage to the environment, they can be treated as a disaster. Appropriate measures must be taken to prevent explosions. These measures are aimed at preventing the formation of explosive atmospheres, preventing the occurrence of ignition sources and limiting the effects of the explosion. Static electricity is one of the sources of ignition of the potentially explosive atmosphere of dust / air. Assessing the occurrence and the possibility of initiating discha...
