Measurement technique and results of evaluating influence of heating microclimate on skin surface temperature in workers engaged into oil thermal mining

The study was aimed to refine a method evaluating level and dynamics of skin surface temperature as an indicator of heat state in a worker exposed to intermittent influence of workplace ambient high temperatures during a working shift. The measurement technique was automated continuous detection with registration of parameters every 5 seconds and the data backup to memory card. Findings are that actual scenarios of heat load on the workers significantly differ from the calculated ones. Mathematic models of relationships between air temperature and skin temperature were obtained and helped to play various scenarios of the workers’ presence in “heat” zones and evaluate them according to criteria of weighted average and maximal skin temperature. Results are thatoCcupational conditions of workers engaged into underground oil thermal mining necessitate specification and implementation of preventive measures and improved regulatory support, concerning creation of safe microclimate parameters.
