僱員採取的任何無視安全法規、標准或慣例的行動都被視為不安全行為。建築工地事故的主要原因之一是建築工人的不安全行為。由於可以減少事故的發生,對工人不安全行為的研究已經引起了很多人的關注。然而,由於來自建築工地的數據不足,很難評估不安全行為。因此,本研究的目標是調查基於不安全行為的預防建築事故的準則和潛在因素。通過訓練有素的調查員,從一個建築工地記錄了2.207個不安全行為。違反《職業安全與健康設備和措施條例》是80%的風險活動的原因。在設定的置信度大於90%的情況下,發現了13條主要規則來解釋基於不安全行為模式的建築事故預防。為了調查印度尼西亞建築工地發生不安全行為的可能性,進行了一項案例研究。印度尼西亞的專業建築工人完成了108份關於不安全行為的問卷調查。使用探索性因子分析提取了三個共同的變量,在列為問卷問題的23個不同的不安全行為中確定了模型的結構。研究結果不僅闡明了不安全行為、安全行為和安全氛圍之間的聯繫,而且還可以幫助安全從業人員針對每種不安全行為製定有效的策略。通過比較兩個國家和兩種方法的結果,還強調了重要的發現。;Any action taken by an employee that disregards safety regulations, standards, or practices is considered unsafe behavior. One of the main reasons for accidents on construction sites is unsafe construction worker behavior. Since it reduces the incidence of accidents, the study of unsafe worker behaviors has drawn a lot of attention. However, inadequate data from construction sites make it difficult to assess unsafe behavior. Therefore, the goal of this study is to investigate the guidelines and latent factors for preventing construction accidents based on unsafe behaviors. By trained surveyors, 2.207 unsafe behaviors were recorded from a construction site. The breach of the Regulation for the Occupational Safety and Health Equipment and Measure is to blame for 80% of risky activities. With the settings confidence value greater than 90%, 13 major rules are found to explain construction accident prevention based on unsafe behavior patterns. To investigate the likelihood of unsafe behavior occurring on construction sites in Indonesia, a case study was conducted. Professional construction workers in Indonesia completed 108 questionnaire questionnaires about unsafe behavior. Three common variables were extracted using exploratory factor analysis to pinpoint the model′s structure among 23 distinct unsafe behaviors listed as questionnaire questions. The results not only clarify the connection between unsafe behaviors, safety behavior, and safety climate but also can assist the safety practitioners to formulate an effective strategy for each type of unsafe behavior. Essential findings by comparing the results for both countries and both methodologies were also highlighted.
