This study aimed to investigate the thermal responses of acclimated workers exposed heat stress in a real work environment. The physiological indices and subjective perception 14 were measured an industrial plant. effects wet bulb globe temperature (WBGT) on studied. differences between unacclimated college students compared analyzed. relationship mean skin sensation was revealed. results show ...

OBJECTIVE: To assess whether ice-water immersion or cold-water immersion is the more effective treatment for rapidly cooling hyperthermic runners. DESIGN AND SETTING: 17 heat-acclimated highly trained distance runners (age = 28 +/- 2 years, height = 180 +/- 2 cm, weight = 68.5 +/- 2.1 kg, body fat = 11.2 +/- 1.3%, training volume = 89 +/- 10 km/wk) completed a hilly trail run (approximately 19 ...

original article   the objectives of this research were to study the correlations of heat strain score index (hssi) and values of wet-bulb globe temperature (wbgt) index with physiological parameters such as core body temperature, heart rate, and blood pressure of workers exposed to heat stress in a glass manufacturing plant in order to determine the reliability of hssi. this cross sectional st...

Abstract Here the development of python library thermofeel is described. was developed so that prominent internationally used thermal indices (i.e. Universal Thermal Climate Index and Wet Bulb Globe Temperature) could be implemented into operational weather forecasting systems European Centre for Medium Range Weather Forecasts) whilst also adhering to open research practices. Th...

Urbanization has resulted in high temperatures cities, which are exacerbated by an increase urban impervious surfaces (road space). This study investigated the effect of road characteristics on roadside temperature. Different temperature indices were measured at four sites Seoul with different designs using weather measuring devices and infrared thermal cameras. The differences between air decr...

Existing methods for estimating heat stress, enshrined in British/International Standards (the Wet Bulb Globe Temperature (WBGT) index [BS EN 27243] and the Required Sweat Rate equation [BS EN 12515; ISO 7933 modi®ed]), assume that the clothing worn by the individual is water vapour permeable; the WBGT index also assumes that the clothing is relatively light. Because most forms of personal prot...

The main focus of this study is to apply a computational tool for the flow analysis of the turbine engine that has been tested with ice crystal ingestion in the Propulsion Systems Laboratory (PSL) at NASA Glenn Research Center. The PSL has been used to test a highly instrumented Honeywell ALF502R-5A (LF11) turbofan engine at simulated altitude operating conditions. Test data analysis with an en...

While climate change continues to increase ambient temperatures, the resulting heat stress exposure to workers in non-climate controlled settings is not well characterized, particularly in low and middle income countries. This preliminary report describes current heat stress in Nicaraguan work places and estimates occupational heat stress in 2050. From over 400 measurements of heat exposure usi...

The focus of this review is upon acute exposure to hot environments and the accompanying physiological changes. The target audience includes physiologists, physicians and occupational health and safety practitioners. Using the principles of thermodynamics, the avenues for human heat exchange are explored, leading to an evaluation of some methods used to assess thermally-stressful environments. ...
