The aim of this study is to record, objectively describe and compare working postures of Brazilian and Norwegian construction electricians. Postures of the upper arms, head, and neck during work and breaks were quantified by means of inclinometry for a representative sample of 12 Brazilian and 12 Norwegian electricians in the construction industry during a full work-shift. Despite that differences were found between specific work-related factors, Brazilian and Norwegian workers revealed a high and very similar level and pattern of postures for all evaluated body regions, suggesting that results could be extrapolated to other electricians. Upper arm elevation was high and similar for both groups and head flexion and extension was pronounced compared to other occupations. Thus, extreme postures were identified for construction electricians in both countries, with similar exposure pattern also for defined tasks (planning, support and wiredraw), suggesting that this job is risky regardless organizational differences.
本研究旨在客观记录、描述和比较巴西和挪威建筑电工的工作姿势。通过倾斜计对 12 名巴西和 12 名挪威建筑电工在整个工作班次期间的工作和休息时的手臂、头部和颈部姿势进行了定量评估。尽管在特定的与工作相关的因素方面存在差异,但巴西和挪威工人在所有评估的身体部位均表现出高度相似的高水平姿势,这表明结果可以推广到其他电工。两组工人的手臂抬高高度相似,与其他职业相比,头部的弯曲和伸展更为明显。因此,在这两个国家,建筑电工的极端姿势都被确定下来,对于特定任务(规划、支撑和穿线)也有相似的暴露模式,这表明无论组织差异如何,这项工作都是有风险的。
