Improving heat stress prevention through targeted education in hot and humid workplaces: a study in a foundry industry

This study demonstrated the critical role of targeted educational interventions in enhancing workers' PAKF to mitigate heat stress risks in thermally challenging industries. By developing and validating a multidimensional questionnaire, the authors provided a robust tool for assessing heat stress-related competencies, which revealed significant improvements in the intervention group's PAKF scores compared to the control group.

The authors recommend mandating regular heat stress training sessions across industries, enforcing real-time temperature/humidity monitoring in workplaces, and legislating standardized rest protocols during high-heat periods. Employers should integrate practical modules on symptom recognition, PPE usage, and hydration practices, while policymakers must prioritize industry-specific regulations that address the unique risks of sectors like foundries, construction, and agriculture. Collaborative efforts among occupational hygienists, employers, regulators, and workers are essential to ensure compliance and sustain the cultural shift toward proactive heat stress management.
