[Use of the WBGT-index for evaluation of the heating microclimate in industrial conditions].

The article covers the results showing relationships between the parameters of human heat status and an integral parameter WBGT index (ISO 72443). The significant strong correlation was shown between WBGT index, average skin temperature and heat sensation, medium correlation was seen between WBGT index, changes in heat content of the body, water losses and pulse rate. Approximate values of WBGT index were calculated for the human doing the light physical work. The stated values describe various heat status taking into account the time of hyperthermia.
