Workers may be exposed to conditions that put their physical and mental integrity at risk, from workplace settings to climate characteristics. Heat stress is a harmful health condition caused by exceeding the human body's tolerance limits, leading to illness and increasing the chance of work accidents. Heat stress indexes, such as the Humidex and the Heat Index (HI), are used to measure these impacts. These indexes are significant as they provide a quantitative measure of the heat stress experienced by workers, taking into account both environmental and individual factors.
This study aims to compare multiple heat stress indexes, relating them to historical Brazilian occupational accident data.
We selected eight indexes and applied multiple correspondence analysis to each one, a statistical method that generates graphs to visualize the association between variables in a database.
The analysis and comparison of the graphs indicated that seven of the eight indexes presented similar behavior. It was also possible to relate ranges of index values with specific characteristics of the accidents.
The technique allowed us to analyze the relationship between climate and work accidents and showed that the choice of the heat stress index does not significantly alter the results for most indexes studied.
从工作场所环境到气候特征，工人可能会面临危及身心健康的状况。热应激是一种因超过人体耐受极限而导致的有害健康状况，会引发疾病并增加工作事故的几率。诸如热指数（Humidex）和炎热指数（HI）等热应激指数被用于衡量这些影响。这些指数很重要，因为它们在综合考虑环境和个体因素的情况下，对工人所经历的热应激提供了一种量化度量。
本研究旨在比较多种热应激指数，并将它们与巴西历史职业事故数据相关联。
我们选取了八个指数，并对每个指数应用多重对应分析，这是一种统计方法，可生成图表以直观呈现数据库中变量之间的关联。
图表的分析和比较表明八个指数中的七个呈现出相似的表现。还能够将指数值范围与事故的特定特征联系起来。
该技术使我们能够分析气候与工作事故之间的关系，并表明对于所研究大多数指数而言，热应激指数的选择并不会显著改变结果。
