摘要
为预防塔机作业吊物坠落引发的物体打击(SFO)事故发生,剖析近5年塔机作业事故调查报告,提取19个高频致因因素,融合实验室决策评价(DEMATEL)和解释结构模型(ISM)方法,厘清致因因素间影响关系,构建致因因素多级递阶层次结构,找出关键致因因素。结果表明:19个高频致因因素分为9个层级,其中安全防护用品使用不当、违规进入或处于危险区、吊物坠落是最高层的表层因素,安全管理制度不完善是最底层的本质因素,现场监督管理不到位、无专项施工方案或不合格是较深层次的致因因素;现场监督管理不到位、安全技术交底不到位、安全管理制度不完善以及安全意识、技能或经验不强是塔机作业吊物坠落引发的SFO事故的关键致因因素。
To prevent SFO accident in tower crane operation,19 high-frequency cause factors were extracted from investigation reports of tower crane accidents in the past five years.Decision-making trial and evaluation laboratory(DEMATEL)and interpretative structural modeling(ISM)were integrated to analyze mutual influence relationship between each cause,ladder level structure of causes were constructed,and key causes were found out.The results show that 19 high frequency causative factors are divided into 9 levels,among which improper use of safety protective equipment,illegal entry or in the danger zone and falling of hanging objects are apparent factors.Imperfection of safety management system is essential factor.Inadequate on-site supervision and management and missing or unqualified special construction scheme are deeper cause factors.And the key causing-factors of SFO accident are inadequate on-site supervision and management,inadequate safety technical disclosure,imperfect safety management system,insufficient safety awareness,skills or experience.
