“…The phenomena of an explosion in enclosed spaces in the cubic shape proceed as deflagration, i.e. combustion occurs at a speed not higher than the speed of sound in the gas mixture before ignition [3]. In presented case, the dimensions of the rooms were similar, therefore it can be assumed that the premises had a cubic shape.…”

“…The most tragic incidents, due to the consequences, caused by the gas explosion in Poland have been widely discussed among other in the paper "Katastrofy budowlane spowodowane wybuchem gazu" [1]. The gas explosion phenomena in enclosed space, called confined explosion, is well known and described in numerous papers [2,3]. One of the effects of these incidents is an explosion overpressure, that can be reduced by explosion relief openings.…”

“…Opening of the relief vent at overpressure of potw allow to reduces the influence of an explosion on the load-bearing structure of the building from pmax to pred, which is also many times lower than maximum value (compare Figure 1). Explosion of gas used in residential and public buildings result in strain of the load-bearing elements with the overpressure value corresponding to the reduced pressure value pstat ≈ pred [3].…”

The article presents the issues of repair works in a multi-family residential building, whose structural and non – structural elements have been damaged and destroyed by a gas explosion and the fire. Gas explosions in residential buildings constitute a small percentage of the total number of building disasters, however, due to the relatively large number of injured people, these incidents are very dangerous [1]. Moreover, the gas explosion often leads to significant material losses and fatalities. Proper assessment of the load-bearing structure after such incident requires an extensive knowledge of the behaviour of structures. The first authority, that issues a decision regarding further use is Construction Supervision Inspector. Until the demolition of the object is ordered, the next step is to provide expert report made by an authorized construction expert, whose aim is to assess the technical condition of the elements of the structure and to determine the scope of necessary repair works. Construction expert, who give such opinion during the assessment of objects immediately after such incident, often has limited access to structural elements, moreover these elements often are covered. Hence, the recommendations contained in these reports often do not include all of required construction works.

Ecology today is becoming increasingly important. Increasing air pollution and greenhouse gas emissions make the search for such fuels which will not have such a negative effect on the environment as the fuel use currently -mainly coal. At present it seems that the substitute fuel can be gaseous fuels (propane-butane, methane). Their combustion is less harmful to the environment and their transport is relatively not very complicated. As it turns out, the use of gas is increasing in industry, automotive, heating systems (power plants that operate in the so-called cogeneration). The increase in demand carries continuous development of gas infrastructure, which in turn may increase probability of failure. As a conclusion of this article, taking into account all the construction disasters induced by the gas, the number of such failures is relatively small. It should be remembered, that the disaster caused by gas explosion may cause very large material and human losses. Not without significance is the impact of gas leakage, eg. of the pipeline on the environment. An example is the methane which is a greenhouse gas, less persistent in the air, but much more active than CO 2 . The article presents selected disasters associated with natural gas or propane-butane and the impact of these gases on the environment because these fuels are most commonly used in most sectors of the economy.
