background: pastry occupation is one of occupations to exposure with heat and significant number of workers works at it. this study is aimed to heat stress and heat strain score index assessment in the pastry workers of isfahan.   methods: this cross sectional and descriptive study was conducted on 360 pastry workers between 10 and 14 hours in the summer of 2012. wbgt index was used for determi...

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...

this paper presents a case study to determine the efficiency of the currently used heat stress indices in correlation with wet bulb globe temperature (wbgt) as a permissible index at a foundry plant and to evaluate the extent of the physiological responses such as heart rate and body temperature in correlation with heat stress indices. the field consisted of a foundry plant where a shift work w...

This paper deals with the indirect evaluation of the natural wet bulb temperature, t (nw), one of the two quantities forming the basis of the well-known wet bulb globe temperature (WBGT) index, considered worldwide to be a suitable and user-friendly tool for the preliminary assessment of hot thermal environments. This quantity can be measured by a wet bulb thermometer (a temperature sensor cove...

OBJECTIVES This report describes the thermal stresses and strains during competitive singles tennis. METHODS Thermoregulatory responses were investigated during best of three set tennis matches among 25 players. A total of 86 observations were made from 43 matches played, covering each season, with ambient temperatures ranging from 14.5 to 38.4 degrees C. Core body temperature and skin temper...

OBJECTIVES To examine the incidence, clinical state, personal risk factors, haematology, and biochemistry of heat exhaustion occurring at a deep underground metalliferous mine. To describe the underground thermal conditions associated with the occurrence of heat exhaustion. METHODS A 1 year prospective case series of acute heat exhaustion was undertaken. A history was obtained with a structur...

Global warming causes a temperature rise and alteration of other meteorological variables that directly or indirectly affect human comfort. The wet bulb globe (WBGT) incorporates the effects multiple to provide reliable measure thermal stress. Despite large significance WBGT on public health, studies related characterization trends assessment are limited in tropical humid region like Peninsular...
