A review of heat stress evaluation indices in extremely hot environments

Selecting appropriate evaluation indices to evaluate extremely hot environments has become an urgent problem ensure the safety of workers’ lives and improve labor productivity. The objective this review is compare relevant for assessing heat stress analyze more effective ones applicable industrial environment by considering each one together. Based on extensive research existing literature international standards, paper introduces definitions its influencing factors. actual needs workers, from a practical standpoint, summarize definitions, advantages, limitations index. As result, emphasizes that thresholds thermal should be appropriately adjusted suit different environments. hazards extreme work can reduced developing new indices, charts, or related strategies. This will provide solid theoretical foundation environmental control schemes harsh working situations.
