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...

An attack with a "improvised" explosive device (IED) is when someone uses a bomb and/or destructive device to cause damage, render someone helpless, harass, or divert attention. Terrorists, criminals, vandals, suicide bombers, and rebels all utilize IEDs. IEDs can take many different shapes because they are improvised; they can be as simple as a pipe bomb or as complex as a sophisticated weapon that can inflict significant damage and casualties. IEDs can be transported or carried in a car; they can also be deliver...

In chemical processes, fire and explosion prevention is crucial, especially when flammable liquids or gases are present because they can create explosive atmospheres of gas or vapour in the air. These include oil-based products and organic solvents. It is essential to understand these compounds' characteristics as well as the size of an explosive atmosphere. Explosion hazards as well as the locations where explosive atmospheres are present can be identified and assessed. Safety data sheets also contains crucial in...

Explosions may have severe consequences on the integrity of structural or nonstructural elements of a building. Being considered events with a low probability of occurrence, they are not considered directly in the design, except in certain special situations (accidental design situations). In the case of deliberate attacks, placing explosive devices at short distances or even attached to building elements can cause major local failures. Local failure and potential loss of load carrying capacity are dependent on lo...

Underground mining remains one of the most dangerous occupations in the world, and coalmining is known for its high accident rates. In this paper we aim to present an overview of safety in the extractive industry and we will present statistics on known accidents. The repeated occurrence of explosions in underground mining raises questions about the measures taken to prevent their occurrence. Hazard identification and risk analysis are necessary to identify adverse events that may lead to a hazardous situation, to ...

Unlike friable rocks, salt behaves pseudoplastic when blasted, which leads to other premises of the blasting technique compared to those applied for stratified sedimentary or eruptive rocks. Here can also add the salt inhibitory character on the thermodynamic parameters of the explosions, with effects on their efficiencies as well as some particularities of the execution of the blasting works due to the presence of methane gas in the salt mines. The article presents the results of the research carried out in fired...
