In India's fast-growing economy, the construction sector offers significant developments with huge employment opportunities but poses risks due to poor working environments and uncomfortable postures. Traditional methods, such as manual material handling, can lead to health hazards and musculoskeletal disorders such as overexertion, low back pain, etc.
The purpose of this study was to analyze the working postures of unorganized employees engaged in residential buildings using Ergofellow software and to recommend changes in their unsafe working postures.
Participants' working positions were video recorded and the postures were analyzed using Rapid Upper Limb Assessment (RULA), Rapid Entire Body Assessment (REBA) and Ovako Working Posture Analysis (OWAS). Paired sample t-tests were used to analyze significant differences between the RULA and REBA scores after the ergonomic interventions were implemented.
From the analysis of RULA, REBA and OWAS, the working postures showed a high risk of potential injury and required an immediate change in employees' working postures. The RULA and REBA scores were subsequently lower after the ergonomic interventions, which were based on ergonomic and safety principles. The paired sample t-tests with p-values of less than 0.05 demonstrated decreased risks after ergonomic interventions.
Working postures of the construction workers exposed to musculoskeletal disorders were examined and the ergonomic interventions were implemented. According to the recommendations, working positions were changed, and employee well-being was enhanced by reduced operational risks.
在印度快速发展的经济中,建筑行业发展显著,提供了大量就业机会,但由于工作环境恶劣和姿势不舒适而带来风险。传统方法,如人工搬运材料,可能导致健康危害和肌肉骨骼疾病,如过度劳累、腰痛等。
本研究旨在使用Ergofellow软件分析从事住宅建筑的非正规员工的工作姿势,并建议改变他们不安全的工作姿势。
对参与者的工作姿势进行视频记录,并使用快速上肢评估(RULA)、快速全身评估(REBA)和奥瓦科工作姿势分析(OWAS)对姿势进行分析。在实施人体工程学干预后,使用配对样本t检验分析RULA和REBA分数之间的显著差异。
通过对RULA、REBA和OWAS的分析,工作姿势显示出潜在受伤的高风险,需要立即改变员工的工作姿势。基于人体工程学和安全原则的人体工程学干预后,RULA和REBA分数随后降低。p值小于0.05的配对样本t检验表明人体工程学干预后风险降低。
对暴露于肌肉骨骼疾病的建筑工人的工作姿势进行了检查,并实施了人体工程学干预。根据建议,改变了工作姿势,并通过降低操作风险提高了员工的幸福感。
