Assessment of Occupational Heat Stress in A Selected Indonesian Steel Mill

Introduction: Workers in the Indonesian steel manufacturing industry are subject to many heat stress risk factors, ranging from equatorial climate physically demanding work tasks which may result heat- related illnesses and reduced worker productivity. Hence, a study was conducted at Steel Mill X assess level of among its workers, determine association factors provide meaningful recommendations. Methods: This uses descriptive cross-sectional method workers’ with individual, occupational symptoms. An online questionnaire used collect primary data yet WBGT monitoring were provided by as secondary data. Results: The score ranged 48 140 (M=89.8, SD=±31.0). 122 workers very high-risk category (75.8%). Occupational had statistically significant includes: area, length exposure, air movement, hot surfaces, confined space, clothing WBGT; while stress-related symptoms associated include headache, fatigue, profuse sweating, extreme thirst increased body temperature. absence between individual eliminates it confounding factor, suggesting main variable. Conclusion: Control measures such improving supply drinking water maintenance cooling systems should be implemented soon possible prevent workers.
