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...
