Using a multiplicative bioclimatic indicator model to determine local safety conditions for work outdoors
Abstract
In the present work, the chilblain risks for groups operating in the open air in the areas of falling rocket carrier separable parts launched from the Vostochny cosmodrome for specific time intervals of the 2017-2018 winter season were evaluated. The substantiation of the choice of the multiplicative bioclimatic indicator model and the criterion condition for the values of the desirability function Di > 0.37 is presented. The chosen criterion condition preserves the possibility of working outdoors without frostbite of open body parts. Using a multiplicative bioclimatic indicator model of weather severity, combinations of air temperature and wind speed were calculated for certain territories, under which the weather severity conditions are «satisfactory and better». Specific time intervals have been established, when the ability to work outdoors without frostbite of open body parts remains at a certain level. The results can be used in operational work, when planning work in harsh weather conditions, as well as for a short-term forecast of working conditions in the open air without the risk of injury from cold.
