“…Исследования интенсивности теплового излучения на рабочих местах операторов при нахождении у сушил показали превышение допустимой величины только при выполнении работ (150-240 Вт/м2 при допустимой 140 Вт/м 2 ). Приведенные значения факторов производственной среды подтверждаются и данными работ [3][4][5][6][7][8][9][10].…”

The results of a comprehensive assessment of working conditions for operator‑casters on automatic lines are presented, including the factors of the production environment that determine these conditions. It has been established that a comprehensive assessment of the working conditions of operator‑casters should take into account the factors of the production environment and their absolute values when performing individual technological operations in obtaining castings.

“…Известно, что при воздействии теплового излучения пожара на человеческий организм наблюдается существенное влияние на протекания биохимических процессов, изменения теплового и солевого баланса. Последствием такого воздействия могут быть сердечно-сосудистые нарушения, интенсивное потоотделение, ухудшение зрения [1,2].…”

It is shown that the task of taking into account the impact of thermal radiation from a fire for determining safe distances for situating fire engines and choosing positions for firefighters during developing operational fire extinguishing plans for industrial buildings with enlarged window openings is not fully supported by the functionality of existing software systems. Since thermal radiation as one of the components of dangerous fire factors valuable only with a sufficient exposure, we analyze events tree branches associated with the process of diffusion combustion on the surface of a flammable liquid spill. Algorithms of the fire temperature regime module in the room of an industrial building with an enlarged window opening are presented based on an integral model and the module of the directional pattern of thermal radiation through window openings. The results of numerical modeling using the presented software product allow us to conclude that the effect of thermal radiation diaphragmization by window openings weakens with distance from the front of the heat-emitting surface and becomes negligible at distances of five meters and more.

Expert assessment of the effectiveness of measures to improve working conditions in foundries

2022

The expert evaluation of the effectiveness of measures to improve working conditions in foundries using the integrated assessment methodology is considered. Four classes of foundries have been established according to working conditions, which are determined by a complex of factors of the production environment. The possibility of using it to select the most optimal option in the development of projects of reconstructed foundries or workshops and the implementation of measures to improve working conditions is shown. To evaluate the developed methodology, it was tested on the example of the organization of a foundry with a small-scale production. The technique has shown its high efficiency in choosing the optimal placement of equipment.
