Hydrogen is gaining popularity as a fuel source for more and more fields around the globe. The use of hydrogen for transport represents one of the important applications of this chemical substance, in this sense the development of infrastructures, but especially the safety of hydrogen filling stations representing an important element. Using hydrogen to power transportation can reduce harmful ozone-depleting emissions while improving air quality. Hydrogen fuel cell vehicles can help improve air quality and solve c...

Given the large interest for future uses of hydrogen, special safety measures have to be implemented for avoiding potential accidents. The broad objective of the research study is represented by the development and testing of experimental models representing areas of analysis and study for the initiation and combustion of air-hydrogen mixtures, respectively by numerical modelling of these phenomena, in order to obtain appropriate input data sets for precision computer simulations of chemical explosions of air- hyd...

Explosive atmospheres may occur both in underground mining, as well as in surface industries such as the oil and gas, chemical, petrochemical, wood or baker industries, basically in all industries which extract, process, use, transport or store flammable substances. Within the European Union, Directive 2014/34/EU regulates the placing on the market of equipment, protective systems and components intended for use in such hazardous atmospheres. In this regard, for proofing the compliance with the essential safety re...

The significant increase in the price of energy resources leads today's society not only to a reconsideration of energy conservation policies but also to the encouragement of architects, builders, and building owners to use thermal insulation and exterior wall finishing systems. The design of thermal insulation for facades is a constructive decision, in which the layer with thermal insulation properties is fixed on the load-bearing side of the walls, with the help of adhesives and/or by mechanical means, followed ...

The heat transfer from the source of initiation to the adjacent surfaces is a physical phenomenon worth considering in the process of analyzing the fire. This complex phenomenon describes how the transport, exchange, and redistribution of the thermal energy are carried out and is based on the theoretical knowledge that describes the initiation and fire evolution in time. Flames transfer heat from nearby surfaces through two physical processes, convection, and radiation. A third mode of heat transfer is conduction,...

Worldwide, fires have always been a topical issue, being events with a high occurrence probability, followed by significant material and sometimes, human losses. Statistics show a slightly decreasing trend in the number of fires reported in recent years, respectively in terms of casualties, reflecting an increasing focus on fire safety, through national regulations and legal provisions. Fire sprinkler systems frame into the category of active fire protection and control systems. They are fire extinguishers using d...

The evacuation time of occupants in a fire event is a particularly important parameter, both for the development of emergency evacuation plans and in the post-event investigation. To estimate this time, the classic approach uses alarm / evacuation trials. These simulations involve the allocation of human and financial resources and have the disadvantage of not being able to cover a wide range of technically possible critical scenarios. Moreover, it has been shown that in real fire cases, human behaviour can be sig...
