ABSTRACT
On the basis of analysis of occupational accidents at mining and oil-and-gas enterprises, it has been established that the level of occupational accidents has a seasonal nature. Logical seasonal variations of accident rates have been considered, not only taking into account durations of stay in difficult weather conditions, but also changes of the general energy consumption of the workers, which depend on the temperature factor in the resident region. On the basis of analytical research on changing energy consumption of work in the various climatic zones, mathematical formulas (equations) have been derived for definition of duration of physiologically necessary rest, which depends on the temperature factor for different works. Comparison of results of calculations employing the technique (methodology) of an estimation of labor’s gravity with results of experimental data from other researchers, received in the different years and for various professions, has shown more than satisfactory convergence. This has formed the basis for development of the new energy criterion for estimation of danger in receiving injuries by workers in difficult weather conditions. The estimation of an existing scale of labor’s severity (energy consumption) by means of a new criterion has shown that there are limiting temperatures, which change the normative category. Nowadays, this factor isn’t considered at the certification of workplaces, although there is a close connection between the danger of receiving injuries during work and its severity. For evident representation of change of labor’s severity, which depends on the temperature factor, maps have been constructed, similarly to maps of climatic division into districts (zoning). Maps have been created on the basis of the complex account of viewing time of the temperatures, values of which were below the calculated limiting temperatures of change of labor’s severity. The new indicator of thermal loading, measured in «hourdegree», has been proposed for a more objective picture. Construction of maps has been made for northern areas of the country, where the estimation of energy costs change from temperature is most expedient. Usage of these maps in an aggregate with the executed calculations will serve as the basis for developing a new methodology of workplace certification that further leads to a decrease in industrial traumatism at enterprises of northern regions.
