It is state-of-the-art that a Level 1 PSA also includes a fire PSA for all plant operational states. In performing Fire PSA not only the malfunction of the components has to be assessed but also all supply systems and cables have to be traced for a given component. In the past it was assumed in the case of a fire in a compartment that all components and cables in that compartment are not functional anymore. However, this is in many cases a too conservative approach and could lead to overestimated fire induced core damage frequencies. Therefore, a method is necessary to assess in a more realistic manner the effects of cables failures caused by fire. Such a procedure requires a sound data base on equipment, list of cables and their properties as well as cable routing. Two methods are described which are currently developed. One of them is a cable failure mode and effect analysis which is easier to apply in practice.

Composites structures are widely using in varied fields of industry, where it has to take into account changes of temperature or it is possibility of fire hazards. Heat transfer and fire conditions in composites are very often analysis issues nowadays. A large amount of research in area of modelling heat transfer and fire loading of composites has been performed for both experimental studies and modelling and simulation. The most common areas of analysis of thermal composite structures are: multiscale modelling of heat transfer, simultaneous fire and mechanical loading, fire involved failure and temperature distribution under fire and elevated temperature conditions. This paper presents analysis of heat transfer in composites with taking into account their shape and thickness. The models include a convection mode of heat transfer. The first composite plate is 10 cm wide by 10 cm tall with a thickness of 1 cm. The modified structure has also second part, smaller plate on top 5 cm wide by 5 cm in right corner. They made of glass/vinylester composite. The plates are heating in one, two and three directions. The results are shown in forms of contours of temperature distribution and thermal gradient. Comparison of results for the modelled structures shows differences in the shape and thickness of the analysed structure.

The article is an attempt to reconstruct a symbolic significance of the fire in life of polish family between XIII and XVIII centuries. On the basis of analyze of rich ceremonialism, which can be found in home, household and church space, some types of this element were defined by way of example. The basic merit of a fire is its consumer value, which providing family with life was the base of assessment and creating of additional sense. In symbolic stratum the main role played a ritual fire, which being a part of receiving ritual admitted new members of community (for example, children, women) . There was a fire in magical acts and fortune-telling in everyday practice. Made cyclically or by accident purifying fire protected house and cattle from contagion, dark forces and animal pests. Fire is also a destructive power, of which man was afraid and from which protected his family. The value of flame was also an area of death. Ritual gestures and acts usually used element’s substitutes like candle, smoke, ashes and stove. The rich symbolism of fire, its multi-aspect using and great variety of forms are an evidence of importance of this element in a family’s community space.

Thermal insulation in buildings has been a problem for mankind throughout history. New materials have always been used in this context, and every new material has negative aspects such as environmental, economic and engineering. Although the building exterior insulation materials produced in recent years have made significant progress in terms of thermal comfort, but those with superior properties in resistance to fire are very limited. In this study, considering the environmental sensitivity, the plasters produced from the sands of arenitized granite, micaschist, pumice and expanded perlite rocks and their combinations were applied on expanded polystyrene (EPS), extruded polystyrene (XPS) foams and mineral wool for investigating the fire behaviors of each material. As a result of fire tests, it was observed that the most positive values were gained from micaschist based external isolation board, whereas the board obtained from arenitized granite gave the most negative values. With the combination of natural and environmentally friendly materials such as micaschist, perlite and pumice, on a fire resistant insulation material such as mineral wool, a highly fire resistant, environmentally sensitive and economical insulation material can be produced.

An efficiently working fire protection system in an enterprise, a work place or an institution guarantees the proper execution of fire protection duties. Its proper organisation is of key importance. The conditions of the proper organisation of the fire protection system in a given organisational unit are above all the universality in the scope of using applicable provisions, knowledge of applicable provisions, appropriately exercised supervision of usage of applicable provisions, orders and established rules of conduct. The aim of this paper is to specify the most important duties of owners, users or managers in providing protection against fire or other local risks. This results from the fact that given the variety of operating enterprises, the character of their activity, kind of production and used technology, size, fire risk, etc. it is not possible to determine a standard model of a fire protection system for a particular work place.

Lech Piwowar was connected, inter alia, with the Cracow Writers’ Association (1929–1930), with the literary and artistic societies “Litart” (1931–1935) and “Volta” (1935–1937), since 1933 he closely cooperated with the Visual Artists’ Theatre “Cricot” and published in the magazines “Naprzód”, “Gazeta Artystów” and “Tygodnik Artystów”. According to Heronim Michalski, Piwowar was a “keen student” of Tadeusz Peiper, according to Julian Przyboś – he was a “faithful and fanatical” student. The author of this article devoted to Piwowar focuses on his poems employing explosive imagery, motifs of fire and blood, primarily within the current of social, “committed poetics” (e.g. Spring, Build!, or A Beauty’s Funeral recalling the revolutionary Cracow of 23 March 1936), poems with a rhetorical exclamation – a call. They lead to questions about the avant-garde imagination annexing (making more substantive) the proletarian gesture of dissent, an expression of revolt.

This article aims at presenting the basic principles of designing steel structures according to Eurocode PN-EN 1993-1-2, i.e. with respect to ensuring the appropriate level of safety for such structures in case of a fire developing into flashover. The load-carrying capacity of a steel structure, serving as an example, was assessed on the basis of a static strain-stress analysis. The analysis was conducted regarding changes in the temperature of structural members, both the exposed and the fireproof protected ones, under fire conditions.

Temperature distribution usually observed in steel beam-to-column end-plate joint after 15 minutes of its standard fire exposure is presented and discussed in detail. Two types of joints are analysed for comparative purposes. The first one is a pure steel connection while the other is covered by a reinforced concrete slab. Numerical simulation of the considered joint heating scenario was performed using the 3D model in the ANSYS environment. Some results were additionally verified by simpler calculations carried out on 2D models using the SAFIR computer program. It is emphasized that due to the local accumulation of many massive steel plates the representative temperature values identified in particular joint components are significantly lower than those which at the same time are measured in beam and column outside the connection. This means that the classic assumption of even temperature over the entire length of all the structural elements of a frame load-bearing structure exposed to fire at any time during such fire, without distinguishing in the formal model any cooler nodal elements, is always safe but very conservative. In addition, as the fire develops the differentiation between the temperature values relating to the beam web and to the beam flanges becomes more visible. This effect is particularly significant in the presence of a massive floor slab adjacent the upper flange of a frame I-beam which effectively cools it.

Fires in natural ecosystems cause catastrophic consequences on a global scale. These fires are caused by landscape-transforming factors, which include dust and gas pollution of the atmosphere, destruction of forests and living organisms, pollution of ecosystems with dangerous toxic compounds and heavy metals. The aim of the presented research is to investigate the influence of ground forest fires on the concentration of mobile forms of heavy metals in different soil horizons. Sampling of soils of pyrogenic origin was carried out from 4 plots according to operating standards on the territory of Rava-Rusky forestry near the village of Lavrykiv, Zhovkva district, Lviv region (Ukraine). Soil sampling for investigation of migration of heavy metals was carried out taking into account the number of years spent after burning of meadow vegetation and forest litter. The most contaminated with heavy metals is site #2 (completely burned out 2 years before the experiment). There is a significant accumulation of cadmium in edaphic horizons (0.31 – 0.66 mg/kg), the value is close to the maximum allowable concentrations for soils (0.7 mg/kg). Also in this area the highest content of mobile forms of nickel (1.52 – 2.80 mg/kg) was detected, while the maximum allowable concentrations for soils is 4 mg/kg. The lowest content of heavy metals is in the site #1, which was exposed to fire long before the start of monitoring – 3.5 years. Here the values of mobile forms of heavy metals are close to the background. Vegetation in burnt areas at the first year of post-pyrogenic development is characterized by spontaneous single species. In 2–3 years it is characterized by a group arrangement. Complete natural overgrowth of the burnt area (natural vegetative reclamation) occurs 4–5 years after combustion. Monitoring the impact of ground forest fires on the concentration of heavy metals in edaphic horizons is important in terms of environmental renaturalization and the development of preventive measures for forest fires and fires in natural ecosystems.
