The purpose of this study is to provide industry practitioners with a better understanding of the impacts of high-temperature conditions on construction labor productivity. Such information could assist in the establishment of plans to prevent heat-stress injuries and help improve the safety and comfort of construction labor working environments. On-site WBGT (Wet Bulb Globe Temperature) data a...

Ultra Violet (UV) parasols are a reasonable countermeasure against heat stress as they portable and inexpensive. This study compared the mitigation effect of UV parasol with that street trees dry-mist spraying on hot humid summer day in Japan. We observed meteorological elements calculated universal thermal climate index (UTCI) wet-bulb globe temperature (WBGT) under parasol, trees, spraying, d...

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...

In 1974 two sets of heat stress guidelines, each based on the wet bulb globe temperature (WBGT) index, were designed for men's National Collegiate Athletic Association (NCAA) Championship Division I distance running competitions. One set of guidelines was established to minimize the chance of heat injury during distance running events. A second set was designed to predict heat stress related pe...

BACKGROUND There seems to be a discrepancy between the available heat stress guidelines and the actual risk of heat-related illness among professional beach volleyball players competing under hot and humid conditions. OBJECTIVE To monitor heat stress and record cases of heat-related medical forfeits on the Swatch FIVB Beach Volleyball World Tour. METHODS The FIVB Heat Stress Monitoring Prot...

The effect of humid heat acclimation on thermoregulatory responses to humid and dry exercise-heat stress was studied in six exercise-trained Thoroughbred horses. Horses were heat acclimated by performing moderate-intensity exercise for 21 days in heat and humidity (HH) [34.2-35.7 degrees C; 84-86% relative humidity (RH); wet bulb globe temperature (WBGT) index approximately 32 degrees C]. Horse...

The U.S. Army has a need for continuous, accurate estimates of the wet bulb globe temperature to protect soldiers and civilian workers from heat-related injuries, including those involved in the storage and destruction of aging chemical munitions at depots across the United States. At these depots, workers must don protective clothing that increases their risk of heat-related injury. Because of...

The objective of the present contribution is to assess the exposure to hot thermal environments in the Portuguese glass industry. For this purpose a field survey was carried out and the measurements took place in industrial units - five industries and nineteen workplaces were considered-so all the results are based on real working conditions. In order to assess the level of heat exposure the We...

Recently, a novel environmental stress index (ESI) which is composed from commonly used meteorological variables: ambient temperature (T(a)), relative humidity (RH), and solar radiation (SR) was suggested as follows: ESI = 0.63T(a)-0.03RH+0.002SR+0.0054(T(a) x RH)-0.073(0.1+SR)(-1); (degrees C) The purpose of the present study was to evaluate and validate the ESI for hot dry and hot wet climati...
