Introduction: Regarding development of several thermal indices and limitations of each, in this research applicability and validity of temperature- humidity index (Humidex) were examined against the standard heat index, Wet Bulb Globe Temperature -WBGT, as well as tympanic temperature of subjects. Material and Method: This cross-sectional study was done on 163 subjects at spring and summer ...
زمینه وهدف: مواجهه با گرما یکی از مسائل عمده در صنایع مطرح می باشد. مطالعه حاضر باهدف ارزیابی ریسک حرارتی، اندازه گیری شاخص استرس و ارائه طرح کنترل گرما در ایستگاه های جوش القایی و برش شرکت پروفیل صورت گرفته است. روش بررسی: داده های مطالعه از طریق اندازه گیری پارامترهای فیزیکی با استفاده از دستگاه wbgt دیجیتال و دماسنج کاتا نقره اندود انجام شد. احساس راحتی افراد بر اساس میانگین رأی پیش بینی ش...
Introduction: Heat is one of the hazardous physical agents in the workplace. Exposure to heat and consequent thermal stress influence workers productivity in addition to adverse health effects. The aim of this study was to determine the heat stress induced productivity loss related to different tasks of farmers in Darreh Shahr city, during summer. . Material and Method: This cross-sectional stu...
Introduction: Outdoor workers are exposed to heat from solar radiation and the atmospheric conditions, in addition to the heat from the working process, which is worse by global warming. The purpose of this study was to evaluate heat stress based on wet bulb globe temperature index and also to examine the relationship between WBGT and physiological indices among outdoor workers of Shabestar cit...
Background & Aims of the Study: Heat Stress is a major factor in many industrials and heat stress is one of occupational hazards in the workplace and severely affects the health and productivity, heat stress can decrease efficiency, increase accidents and reduce safety levels. Aim of this study was comparing the heat stress indices of HSI and WBGT and core body temperature in steels ind...
Background &Aims of the Study: Nowadays heat stress is one of the most current harmful physical agents in workplaces. Attentions to recognized consequences of heat stress and have no information about heat stress in Ardabil bakeries, this study have been done in 2013. Materials & Methods: This cross sectional research has been done in 96 different bread types bakeries in ...
most of iranian oil terminals are located in tropical regions and consequently, disorders of heat stress among workers are expected. there are many heat stress indices with self-advantages and disadvantages which are used for evaluating the amount of heat stress. the aim of the present study was to evaluate the reliability of wbgt, et and cet indices by comparison to core body temperature in kh...
This study assesses heatstroke risk in the near future (2031–2050) under RCP8.5 scenario. The developed model is based on a generalized linear with number of ambulance transport due to (hereafter patients heatstroke) as explained variable and daily maximum temperature or wet bulb globe (WBGT) explanatory variable. With temperature, we performed projection case considering only climate change (C...
