  Background and Aims: Hot and humid conditions are common in many parts of the world these conditions can influence both the health and performance of individuals. Therefore to describe the environmental conditions appropriately, the amount of reliability of heat stress indices should be measured. The aim of this study was evaluating the reliability of WBGT and P4SR by comparison to core body temperature in an OilTerminal.

  Methods: The participants (94 persons) were two groups of acclimatized and not acclimatized employees of different units of the Oil Terminal. After identifying the units and their activities, air and wet temperatures, WBGT, and core body temperature (oral and tympanic) were measured in three situations including outdoor, indoor, and rest activities.

  Results: The statistically significant correlation was found between above mentioned heat stress indices with oraland tympanictemperatures (P<0/05) . The regression equations were shown that the most determinant coefficient belong to WBGT and tympanic temperature (R2=0/571) .

  Conclusion: It was found that the WBGT and P4SR with core body temperature had significant correlations and WBGT had the most accuracy to predict heat stress in employees.
