Several heat indices have been developed in industrial health, but each has its limitations.
The objective of this article is to determine the validity and applicability of a temperature-humidity index, named Humidex compared with the Standard Wet-Bulb Globe Temperature (WBGT) index (ISO 7243).
This cross-sectional study was conducted in the summer of 2019, in a tile factory in the west of Iran. 59 measurements were performed in 8 different workstations. Environmental parameters including natural wet bulb temperature (Tnw), dry bulb temperature (Ta), globe bulb temperature (Tg), and heat stress (WBGT) were measured. Humidex was calculated according to an equation. SPSS software (version 16) was used for data analysis.
There was a high correlation between Humidex and WBGT in the estimation of heat stress (R=0.912, P<0.001). The Kappa Coefficient between Humidex and WBGT was 0.298, P=0.001.
Humidex is highly correlated with WBGT. Humidex can be used instead of the WBGT index, especially in hot and humid environments.
工业卫生领域已开发出多种热指数,但每种都有其局限性。
本文的目的是确定一种名为温湿指数(Humidex)的温度 - 湿度指数与标准湿球黑球温度(WBGT)指数(ISO 7243)相比的有效性和适用性。
这项横断面研究于2019年夏季在伊朗西部的一家瓷砖厂进行。在8个不同的工作站进行了59次测量。测量了包括自然湿球温度(Tnw)、干球温度(Ta)、黑球温度(Tg)和热应激(WBGT)在内的环境参数。根据一个公式计算温湿指数(Humidex)。使用SPSS软件(版本16)进行数据分析。
在热应激评估中,温湿指数(Humidex)与WBGT之间存在高度相关性(R = 0.912,P < 0.001)。温湿指数(Humidex)与WBGT之间的Kappa系数为0.298,P = 0.001。
温湿指数(Humidex)与WBGT高度相关。温湿指数(Humidex)可替代WBGT指数使用,尤其是在炎热潮湿的环境中。
