This study aimed to evaluate the workers safety behavior and to determine the importance of each unsafe behavior in an Iranian steel manufacturing company.
This study was conducted in Mobareke steel manufacturing company, which is located in the middle of Iran, in 2007. The methodology was based on the safety behavior sampling (SBS) technique and entropy. After specifying the unsafe behaviors and with reference to the results of a pilot study a sample of 3248 was determined, with a sampling accuracy of 5% and confidence level of 95%.
The results indicated that 41.8% of workers behaviors were unsafe. The most frequent unsafe behaviors were inappropriate use of personal protective equipments (PPEs) with 32% of total unsafe behaviors. The results also notified a significant relationship between age, job experience and educational level on unsafe behaviors (P< 0.05). The highest weight, which is obtained by entropy, belongs to using inappropriate tools with weight of 0.1425. The ultimate findings of the study showed that a considerable number of workers' behaviors were unsafe, which is one of the main antecedents of industrial accidents.
Considering catastrophic consequences of accidents in steel manufacturing industry, the results emphasize on diminishing unsafe behaviors and recommends applying behavior based safety principles.
本研究旨在评估伊朗一家钢铁制造公司工人的安全行为，并确定每种不安全行为的重要性。
本研究于2007年在位于伊朗中部的莫巴雷克钢铁制造公司进行。该方法基于安全行为抽样（SBS）技术和熵。在确定不安全行为并参考初步研究结果后，确定了3248个样本，抽样精度为5%，置信水平为95%。
结果表明，41.8%的工人行为不安全。最常见的不安全行为是个人防护装备（PPE）使用不当，占不安全行为总数的32%。结果还表明年龄、工作经验和教育水平与不安全行为之间存在显著关系（P<0.05）。通过熵获得的最高权重属于使用不当工具，权重为0.1425。该研究的最终结果表明，相当数量的工人行为不安全，这是工业事故的主要原因之一。
考虑到钢铁制造业事故的灾难性后果，研究结果强调减少不安全行为，并建议应用基于行为的安全原则。
