“…The exploited building and engineering structures are exposed to the influence of exceptional loads that are difficult to predict, e.g., explosion pressure or fire temperature [ 14 , 15 , 16 ]. The actions taken during the rescue operations and testing of various structures subjected to the temperature of fire differ in the type of equipment used and the type of temporary support structure.…”

The durability of concrete structure members is dependent on several factors that should be analyzed at each stage of the construction process. Omitting any of these factors might lead to the augmentation of harmful interactions and, as an effect, to safety hazards and the degradation of a structure or its parts. The article, based on several years of studies on exploited concrete structures, presents the effects of an incorrect analysis of selected factors resulting in the occurrence of faults significantly influencing the possibility of safe use of the objects. The described cases include, but are not limited to, the consequences of an improper assessment of building conditions after a biogas explosion in a fermentation chamber, the effect of a wood dust explosion, fire temperature and firefighting action on the prestressed girders, the stages of degradation of bearing structures supporting gas tanks exploited in an aggressive environment, and the consequences of omitting the temperature load in relation to the upper surface of a plate covering the fire pond. In each case, methods of restoration of the damaged elements were proposed, and their application to engineering practice was described. The practical aspects of the conducted research and implemented interventions were indicated.

The safety accident of indoor natural gas supply system is the process of natural gas leakage and diffusion, most of which are turbulent processes affected by many factors. When the natural gas leaks into the indoor confined space, it will mix with the air to form a mixture. When the oxygen in the natural gas and the air reaches a certain concentration range, combustion or explosion will occur when it meets the ignition source. This paper mainly introduces the influencing factors and calculation methods of the explosion limit of natural gas, and analyzes the calculation methods of the explosion limit of multi-component combustible mixed gas.

“…In view of distinctive vivacity, the combustion process in closed space in most cases turns out into explosion. Then, uncontrolled closed space combustion is usually considered as the explosive-type threat which mitigation may be acquired by introduction of well-timed venting [6].…”

The method of estimation of maximal parameters of combustion of gaseous mixtures in closed space is presented. Estimation of chemical composition of combustion products is based on simplified rules of decomposition of reactive medium. Exemplary calculations of temperature, pressure, heat of combustion of hydrocarbon/air mixtures are presented. The accuracy of presented method was validated by comparison with calculations performed by thermodynamic numerical code that include wide list of chemical substances present in combustion products. The obtained results confirm applicability of the proposed method to predict closed space combustion parameters of gaseous mixtures. Semi-empirical methods of estimation of flammability limits are briefly referred
