heat stress is well recognized among the hazardous physical agents that might be present during work. this study aims to compare wbgt index at acclimated and unacclimated people to permissible threshold limit value and study the differences between physiological parameters at them. twenty one healthy men were participated in the study. all of the subjects were monitored in two different weather...
results the results showed that the average hr at resting, sitting (32℃ ± 0.1℃), and light workload (30℃ ± 0.1℃) were 78.52 ± 12.10, 69.74 ± 11.98, and 110.78 ± 17.91 beat/min, respectively. the average of ear canal temperature was estimated at 36.70℃ ± 0.36℃ for sitting workload and at 36.71℃ ± 0.27℃ light workload. conclusions the findings of this study illustrated that the average hr and the...
Introduction: Water and electrolytes are essential to maintain the health and performance in hot occupational environments. The aim of this study was to determine the effect of different drinks on indices HSSI, PESI and PSI under laboratory conditions. Methods: This clinical trial study was conducted on 13 male students in hot and dry laboratory conditions, (40 ° C, humidity 30%). In 3 s...
heat stress is a common occupational health hazard at outdoor workplaces especially in a hot-humid climate. overheating of the body can cause a number of problems, including heat rash, heat cramps, dizziness, heat exhaustion, and heat stroke. the present study aimed to assess heat stress indices including di, wbgt, and sw req /phs, as a mean to estimate the heat load on the employees of a petro...
BACKGROUND Heat exposure among construction workers in the Persian Gulf region is a serious hazard for health. The aim of this study was to evaluate the performance of wet bulb globe temperature (WBGT) Index for estimation of heat strain in hot/humid conditions by the use of Physiological Strain Index (PSI) as the gold standard. MATERIAL AND METHODS This cross-sectional study was carried out ...
Abstract Background: Heat exposure is one of the harmful agents at work environments. Workers in high temperature environments are susceptible to heat strain. The purpose of this study was to evaluate the performance of Iranian cooling vests containing phase change material in hot and humid conditions in the Persian Gulf. Materials and Methods: This interventional study carried out on 6 subj...
Introduction: Heat stress is one of the hazardous agents in the steel industries which can threaten the health and safety of workers and lead to serious occupational diseases. The aim of the study was to assess the heat stress in the steel industries and compare PHS (Physiological Strain Index), WBGT (Wet-Bulb Globe Temperature), DI (Discomfort Index) and HSI (Heat Stress Index) indices for the...
Firefighting demands performing heavy muscular work under adverse and potentially dangerous conditions. Although the physiological and psychological responses to simulated firefighting activities have been described, the heat strain has not been characterised using standardised indices of exercise-heat strain. The purpose of the study is to describe the physiological and perceptual strain assoc...
