The working time in work places thermically uncomfortable must be limited in order to prevent the risk of thermal stress. In a previous study we have demonstrated that the best method for calculation of the safe exposure times is based on the required sweat rate index. In the present work we verified in different work places termically uncomfortable, grouped for equivalent values of WBGT index, the variability of the safe exposure times calculated by means of a method just now mentioned for various levels of energetic expenditure. The results point out the possibility of a mathematical relation between energetic expenditure, WBGT index and mean of safe exposure times.
为防止热应激风险，必须限制在热环境不舒适的工作场所的工作时间。在之前的一项研究中，我们已经证明，计算安全暴露时间的最佳方法是基于所需出汗率指数。在本研究中，我们在不同热环境不舒适的工作场所进行了验证，这些场所根据湿球黑球温度（WBGT）指数的等效值进行分组，通过上述方法计算了不同能量消耗水平下的安全暴露时间的变异性。结果指出了能量消耗、WBGT指数和安全暴露时间平均值之间存在数学关系的可能性。
