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...

The continuous development of human society from a technical-economic point of view is closely related to the increase in energy consumption. However, this implies the rapid depletion of existing fossil fuels and an accelerated increase in global pollution. At the moment, to counteract these impediments, one of the most important sources that can be used for the purpose of energy production, without having a negative impact on the environment, is hydrogen. Due to the fact that, when mixed with air, hydrogen can ge...

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...

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...

Many operations with flammable liquids produce flammable atmospheres by evaporation of the liquid being handled. In some circumstances, the flammable atmosphere is not due to the liquid being handled but due to residues of volatile liquid or vapor from earlier operations with the same equipment as is often the case with diesel fuel handling. This paper highlights some aspects regarding the danger of fires and explosions in the transport, storage and distribution of diesel fuel starting from the investigation of th...

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...

The need to provide the highest level of protection in the industrial spaces with explosion danger led, on the one hand, to the development of new types of dissipative textile materials with protective role against static electricity and, on the other hand, to the development of test methods of these materials for the purpose of assessing compliance with the requirements specific to prevent the initiation of explosive atmospheres. The assessment of the compliance of the dissipative textile materials used at the ma...
