Objectives. Despite widespread use of scaffolds on construction sites, they are the most common causes of accidents, injuries and fatalities in this sector. About 80–90% of all occupational accidents occur as a result of human factors. On construction sites, proper erection/dismantling of scaffold is possibly the most essential factor in preventing accidents as it is one of the factors reported to be highly statistically significant in correlation to a high overall scaffold safety rating. Therefore, analysis of human errors (HEs) caused by scaffolders is important to be implemented. The main objective of this study was to evaluate possible HEs during scaffold erection and dismantling (SE&D). Methods. Stages involved were identified using hierarchical task analysis (HTA). Risk values of HEs were then evaluated using the fuzzy analytical hierarchy process (FAHP). Results. Our findings indicate that the highest and lowest risk values were related to the errors of ‘failure to reattach braces and connections prior to dismantling scaffolds’ and ‘insufficient preparation of the firm foundation’, respectively. Conclusion. This study formulates a method to estimate the risk of potential HEs in SE&D.

目标。尽管在建筑工地广泛使用脚手架，但它们是该部门事故、伤害和死亡的最常见原因。大约 80-90% 的职业事故是由人为因素造成的。在建筑工地上，正确安装/拆除脚手架可能是预防事故的最重要因素，因为据报道，它是与高整体脚手架安全等级相关的具有高度统计学意义的因素之一。因此，对由脚手架造成的人为错误（HEs）进行分析非常重要。本研究的主要目的是评估在脚手架架设和拆除 (SE&D) 过程中可能出现的 HE。方法. 使用分层任务分析 (HTA) 确定所涉及的阶段。然后使用模糊层次分析法 (FAHP) 评估 HE 的风险值。结果。我们的研究结果表明，最高和最低风险值分别与“在拆除脚手架之前未能重新连接支架和连接”和“牢固地基准备不足”的错误有关。结论。本研究制定了一种估计 SE&D 中潜在 HEs 风险的方法。
