Over the period 1980-2009, there were 58 documented hyperthermia deaths of American-style football players in the United States. This study examines the geography, timing, and meteorological conditions present during the onset of hyperthermia, using the most complete dataset available. Deaths are concentrated in the eastern quadrant of the United States and are most common during August. Over h...
microsoftinternetexplorer4 زمینه و هدف: استرس گرمایی در بسیاری از صنایع از جمله صنایع پتروشیمی و فولاد یک خطر جدی برای سلامتی و ایمنی کارگران به شمار می آید. ارزیابی استرس گرمایی نه تنها از نظر پیشگیری از بیماری های ناشی از مواجهه با گرما، بلکه از نظر عملکرد و ایمنی کارگران در محیط کار نیز مهم است. شاخص هایی که هم اکنون برای ارزیابی استرس گرمایی مورد استفاده قرار می گیرند بسیار زیاد بوده و انتخ...
Background Thermal component of the atmospheric environment is an important issue which is related to human's health. Thermal environment includes both heat exchange conditions (stress) and the physiological response (strain). The aim of this study was to measure the association of heat indices (PSI, HSI, Humidex) especially subjective one (STI) with some physiological parameters (Blood pressur...
Introduction: Workers in the Indonesian steel manufacturing industry are subject to many heat stress risk factors, ranging from equatorial climate physically demanding work tasks which may result heat- related illnesses and reduced worker productivity. Hence, a study was conducted at Steel Mill X assess level of among its workers, determine association factors provide meaningful recommendations...
Introduction: Global warming is likely to affect certain groups such as workers in heat-producing industries. With limited research exploring an important area, this study aimed explore the heat stress vulnerability and adaptive strategies of indoor small-scale factory workers. Methods: This was a cross-sectional mixed-method approach used. The setting units. quantitative component included env...
بررسی استرس گرمایی در مشاغل روباز مناطق گرم و کویری بر اساس دادههای هواشناسی مطالعه موردی: قم-ایران
اهداف: هدف از پژوهش حاضر، بررسی استرسهای گرمایی توسط شاخصهای دمای تر گویسان (WBGT) و استرس محیطی (ESI) بر اساس دادههای هواشناسی در مشاغل روباز استان قم بهعنوان یک منطقه گرم و کویری است. روشها: این مطالعه بهصورت توصیفی– تحلیلی بر اساس دادههای هواشناسی در چهار ماه خرداد، تیر، مرداد و شهریور سال 1392 انجام شد. پارامترهای محیطی در هر 10 دقیقه از ساعت 7 تا 19 اندازهگیری و ثبت شد. شاخص WBGT ...
The hygienic norms for microclimate are often neglected. The purpose of the study was to assess stress in workers exposed to overheat in the hot period of the year. The microclimate components and wet bulb globe temperature (WBGT) were measured in two units: glass manufacturing unit and iron foundry. Stress was estimated in 15 males, exposed to heat and in a control group of 15 men from each un...
This study evaluated the physiological tolerance times when wearing explosive and chemical (>35 kg) personal protective equipment (PPE) in simulated environmental extremes across a range of differing work intensities. Twelve healthy males undertook nine trials which involved walking on a treadmill at 2.5, 4, and 5.5 km·h(-1) in the following environmental conditions, 21, 30, and 37°C wet bulb g...
Health and productivity impacts from occupational heat stress have significant ramifications for the large workforce of India. This study profiled occupational heat stress impacts on the health and productivity of workers in select organized and unorganized Indian work sectors. During hotter and cooler seasons, Wet Bulb Globe Temperatures (WBGT) were used to quantify the risk of heat stress, ac...
