Stonecutting and setting are important tasks in a construction site. A field study was conducted to assess occupational-related disorders and to conduct ergonomics assessment among stonecutters. The study focused on (a) the duration of work per day, (b) the working environment and working activities and (c) the feeling of discomfort in different parts of the body. A detailed posture analysis was performed with the Ovako working posture analysis system (OWAS). It was observed that stonecutters worked continuously in awkward postures during stonecutting and setting. Consequently, they suffered from discomfort in different parts of their body, specifically in the lower back, knees and shoulders, which mainly prevented them from continuing their work. This study also revealed that stonecutters had to work in congested work areas with a poor level of illumination. The noise level and dust particles emitted during stonecutting activities could affect stonecutters.
石材切割和安装是建筑工地的重要任务。本研究旨在评估石材切割工的职业相关疾病，并进行工效学评估。研究重点关注：(a)每天的工作时长；(b)工作环境和工作活动；(c)身体不同部位的不适感。采用 Ovako 工作姿势分析系统（OWAS）对详细姿势进行了分析。研究发现，石材切割和安装过程中，工人长时间保持不自然的姿势，导致他们身体不同部位感到不适，尤其是下背部、膝盖和肩部，这严重影响了他们的工作。此外，研究还揭示了工人必须在照明条件差、拥挤的工作区域工作。切割石材时产生的噪声和粉尘颗粒也会对工人造成影响。
