This study examines the compatibility of Wet Bulb Globe Temperature (WBGT) limits with a Chinese migrant construction workforce in a tropical climate. The paper looks at the relative weaknesses of WBGT limits in comparison to alternative heat indices, and also explores the unique requirements for managing heat exposure in tropical areas with both acclimatized and unacclimatized workers. The paper addresses the numerous variables that must be taken into account when monitoring and mitigating heat stress in workers generally and then examines heat stress and its effects in the construction industry, tropical climates, and Asian workforces. The paper relates the goal of this research that is to determine a widely applicable, accurate in varying climates, and easy-to-use heat index for the mitigation of heat stress in tropical climates.
From the Paper:"Measuring for heat stress is a nuanced practice, requiring more attention to detail than the common reliance on the WBGT would suggest. First of all, measuring core temperatures is required in order to determine the effects of heat stress on any given individual, and Nagano et al have found that "monitoring temperatures based on a technique involving an auditory canal plug can be used to estimate rectal temperatures accurately, and thereby to avoid conditions leading to heat stress disorders." This is coupled with observations of heart rate and external temperature in order to give an idea as to the physiological reactions to heat stress. However, getting an accurate reading of the subject's core temperature and heart rate is not enough to analyze the effects of heat stress. For instance, the effects of hydration on the body's reaction to heat stress must be taken into account, because the "homeostasis of body water can be difficult to maintain when challenged by strenuous physical work and heat stress" (4). This fact is often disregarded in considerations of heat stress, however, because "implicit in all indices used for risk assessment in the prevention of heat stress is the assumption that workers are healthy and well hydrated" even when this is clearly not the case in reality (3)."
