Background The Deepwater Horizon disaster cleanup effort provided an opportunity to examine the effects of ambient thermal conditions on exertional heat illness (EHI) and acute injury (AI). Methods outcomes were daily person‐based frequencies EHI AI. Exposures maximum estimated WBGT (WBGTmax) severity. Previous day's cumulative effect was assessed by introducing previous WBGTmax into model. Results AI higher in workers exposed above a 20°C (RR 1.40 RR 1.06/°C, respectively). 28°C‐WBGTmax day...
Heat stress exposure limits based on wet-bulb globe temperature (WBGT) were designed to limit exposures those that could be sustained for an 8-h day using limited data from Lind in the 1960s. In general, Sustainable are heat levels at which thermal equilibrium can achieved, and Unsustainable occur when there is a steady increase core temperature. This paper addresses ability of ACGIH® Threshold Limit Value (TLV®) differentiate between exposures, propose alternative occupational limits, ask...
Wet bulb globe temperature (WBGT) index is used by many professionals in combination with metabolic rate and clothing adjustments to assess whether a heat stress exposure sustainable. The progressive protocol systematic method prescribe adjustment value (CAV) from human wear trials, it also provides an estimate of apparent total evaporative resistance (Re,T,a). It clear that there direct relationship between the two descriptors thermal effects diminishing increases CAV at high Re,T,a. There...
There are times when it is not practical to assess heat stress using environmental metrics and metabolic rate, strain may provide an alternative approach. Heat indicators have been used for decades as tools monitoring physiological responses work in hot environments. Common of body core temperature (assessed here rectal Tre), heart rate (HR), average skin (Tsk). Data collected from progressive trials were (1) demonstrate if (PHSIs) at the upper limit Sustainable below generally accepted...
The ACGIH® Threshold Limit Value® (TLV®) is used to limit heat stress exposures so that most workers can maintain thermal equilibrium. That is, the TLV was set an upper of Sustainable for people. This article addresses ability differentiate between and Unsustainable four clothing ensembles over a range environmental factors metabolic rates (M). (woven clothing, particle barrier, water barrier vapor coveralls) represented wide evaporative resistances. Two progressive studies provided data on...
While wet bulb globe temperature (WBGT) is the long-accepted index to represent environmental contributions heat stress, Heat Index (HI) a commonly reported and used for stress guidance. The purpose of this article was propose an HI-based exposure limit. data came from previous progressive studies that identified critical conditions between sustainable unsustainable exposures. experimental trials included five clothing ensembles at three levels each relative humidity (rh) metabolic rate (M)....
