| Summary: | Background and Objective: Heat stress is one of the major safety and health
concern in the oil and gas industry. The main purpose of this study was to
compare the heat stress of oil terminals in northern and southern Iran. In
addition, two physiological parameters were utilized in order to validate
these indices.
Materials and Methods: This descriptive-analytical study was performed on
130 employees working at two oil terminals in Iran (i.e., Kharg and Neka).
Initially, heat stress indices including Hang Seng Index (HIS), Allow
Exposure Time (AET), WetBulb Globe Temperature (WBGT), and Predicted
Four Hour Sweat Rate (P4SR) were measured in this study. Subsequently,
the oral and tympanic temperature of the participants were taken in order to
validate the mentioned indices using Pearson correlation test. The data were
analyzed in SPSS software (version 22).
Results: The results showed a significant correlation between the heat stress
indices of the indoor workplace in Kharg, Iran, and physiological
parameters (P<0.05). Moreover, a positive correlation was observed
between the indices and the parameters, except for HSI. Regarding the oil
terminal in Neka, the oral parameter was also correlated significantly with
AET, WBGT, P4SR. However, there was no significant correlation between
the tympanic temperature and the aforementioned indices (P> 0.05).
Conclusion: According to the results, WBGT and AET are valid indices to
assess heat stress in oil terminals. In addition, it was revealed that the heat
stress in indoor workplace in Kharg oil terminal was higher than that in
Neka oil terminal. |
