Summary
This study on 51 workers found that 12-hour day and night shifts did not negatively impact physiological systems or work capacity. The 12-hour shift schedule is deemed safe for worker health and system reliability.
Area of Science:
- Occupational Health
- Physiology
- Human Factors Engineering
Context:
- Investigated the impact of a 12-hour shift work schedule on 51 workers at "D. Dimov" state works in Yambol.
- Addressed worker complaints regarding the introduction of a 12-hour shift regime.
- Evaluated changes in pulse variability and subjective psychosomatic complaints during day and night shifts.
Purpose:
- To assess the physiological workload and strain associated with 12-hour shift work.
- To determine if the 12-hour shift schedule poses risks to worker health.
- To evaluate the impact on the 'man-machine-environment' system's security and reliability.
Summary:
- No significant physiological overpressure or decrease in working capacity was observed during 12-hour day or night shifts.
- Pulse variability and subjective psychosomatic complaints remained within acceptable physiological limits.
- The study found no evidence of detrimental effects on workers' health status.
Impact:
- The 12-hour shift schedule does not endanger worker health.
- The implemented shift schedule is compatible with physiologically sound work organization norms.
- The 'man-machine-environment' system's security and reliability are not compromised by the 12-hour shifts.
