Controlling heat stress - administrative versus physical control
American Industrial Hygiene Association Journal
|June 1, 1981
Summary
Combining physical and administrative controls is the most effective strategy for preventing heat stress. This approach protected 120 employees over six years, resulting in only three documented cases.
Area of Science:
- Occupational Health
- Environmental Physiology
- Workplace Safety Management
Background:
- Heat stress poses significant risks in occupational settings.
- Evaluating the efficacy of various heat stress prevention strategies is crucial for worker well-being.
- Understanding the interplay between different control measures enhances protective outcomes.
Purpose of the Study:
- To assess the collective effectiveness of multiple heat stress prevention measures.
- To explore the relative merits and interrelationships of physical and administrative controls.
- To determine the optimal strategy for managing heat stress in a labor force.
Main Methods:
- Evaluation of combined physical and administrative controls for heat stress prevention.
- Analysis of interrelationships between different control measures.
- Longitudinal study over six years monitoring environmental conditions and health outcomes.
Main Results:
- A combination of physical and administrative controls proved more effective than single measures.
- The implemented preventive measures protected 120 employees over 2.4 million man-hours.
- Average temperatures ranged from 26.6°C WBGT (non-summer) to 34.4°C WBGT (summer).
- Only three cases of heat stress were documented during the study period.
Conclusions:
- Integrated physical and administrative controls offer superior heat stress management.
- The study demonstrates a highly effective, multi-faceted approach to workplace heat stress prevention.
- This strategy significantly minimizes heat-related illness in demanding work environments.
