Abstract

For the English full text of the article please see the attached PDF-File (English version follows Russian version).ABSTRACT The industrial safety system has evolved on railways for decades. In new economic conditions, many of its basic principles have been preserved, but those factors have emerged that require additional scientific analysis, experimental verification, and modern technological tools. In particular, using the example of construction and maintenance of bridge structures, the situation with labor safety, injuries, and fire hazards at railway transport facilities is studied and assessed. Factorial analysis of labor safety using different criteria is shown. Additionally the results confirm the effect of fire protection on flammability of wood: the effect is manifested in a more intense charring of the surface layer, which creates a barrier to heat the underlying layers, and in a decrease in concentration of combustible gaseous products of thermal decomposition. The results of the experiments allow to determine the directions of improvement of flame retardants, including through the use of additives that maximize the degree of expansion (thermal expansion) of the coatings Keywords: railway, labor safety, bridge works, nomogram of working conditions, injuries, fire protection equipment.
