Assessment of labor conditions class by the intensity of heat treatment by the method of diagrams when changing the layout of technological equipment

Abstract

Introduction. Failure to comply with the requirements for the technological microclimate can lead to the development of occupational diseases and accidents. Therefore, in the general system of measures that ensure normal working conditions, one of the most important tasks is to reduce heat emissions.

Problem Statement. The paper studies the thermoradiation mode of workplaces. For this purpose, a scientific method based on the construction of radiation diagrams is used. The irradiation field of an object is based on the radiation diagrams of various sources that affect the working space.

Theoretical Part. Diagrams are used to express the quantitative parameters and boundaries of the distribution of radiant flows in the total field of irradiation of the workplace. Diagrams are built for different operating modes and operations based on theoretical calculations or real measurements. The method of diagrams is considered on the example of the cementation section of the foundry. The result of replanning, i.e. changing the location of the furnaces installed in the room, is shown.

Conclusion. The study of the intensity of thermal irradiation of the workplace by the method of diagrams showed that changing the layout of production equipment, as well as protection by distance, helps to reduce heat radiation and thus ensure compliance with sanitary and hygienic standards adopted for production facilities.
