Abstract

Physical fatigue, often encountered during various tasks in construction sites, presents a significant hazard when combined with the external environment. This study investigates the interplay between fatigue, body stability, and hazards within the construction industry. An experimental approach was employed to explore the relationship between worker fatigue and body stability while examining how body stability changes with varying levels of fatigue in a hazardous environment. The Harvard step test was utilized to induce quantifiable and varied levels of fatigue among participants, who then performed the experiment in four distinct construction environments across six fatigue levels. Findings indicate that an escalation in fatigue corresponds to a reduction in physical stability, particularly beyond a certain fatigue threshold, leading to a significant decrease in overall stability. Moreover, the results demonstrate that heightened fatigue levels can induce greater decreases in worker physical stability, not only by diminishing physical stability but also by impacting hazard responses. The outcomes of this study substantiate the connection between worker fatigue and physical stability at construction sites and serve as foundational data for the implementation of an effective safety management system that takes into account worker fatigue levels.

건설 현장 내의 다수 작업은 신체적 피로도를 동반하며, 이러한 피로도는 외부 환경과 결합되어 위험을 야기할 수 있는 주요한 요소 중 하나이다. 이 연구는 건설 산업에서 피로, 신체 안정성 및 위험원 사이의 관계를 분석하는 것을 그 목적으로 한다. 이를 위해 작업자의 피로와 신체 안정성 간의 관계를 조사하고 위험 환경에서 피로 수준에 따른 신체 안정성 변화를 조사할 수 있는 실험을 디자인하고 수행하였다. 정량적이며 다양한 수준의 피로도를 제공하기 위해 하버드 스텝 테스트를 통해 실험참가자에게 피로도를 가했으며, 참가자들은 다양한 수준의 피로도 상황에서 4가지의 건설 환경에서 실험을 수행하였다. 실험 결과를 통해 피로도의 증가는 신체 안정성의 저해와 연관성이 있음을 보였으며, 특히 일정 수준 이상의 피로도의 경우 신체 안정성을 크게 떨어트림을 확인할 수 있었다. 또한, 높은 수준의 피로도는 단순한 신체 안정성의 저하뿐 아니라 위험원에서의 반응을 통해 작업자의 신체 안정성을 보다 크게 저하시킬 수 있음을 보였다. 본 연구 결과는 건설 현장에서 작업자 피로와 신체 안정성의 관련성을 확인하며, 작업자의 피로 수준을 고려한 효과적인 안전 관리 시스템을 구현하는 데 기초 데이터로 활용될 수 있을 것이다.
