某机电安装公司承担了某化工装置安装工程，组建了施工项目部。2010年7月22日11时左右，施工作业队某焊工在离地面约10m高的钢结构顶部进行钢结构焊接工作。在操作过程中，该焊：【在往侧向移动时脚踏在了一个探头跳板上，探头板侧翻，焊工不慎从操作平台上跌落，坠落过程中安全帽脱落，焊工头部着地。送医院抢救途中死亡。】
经事故调查，焊工当时在钢结构顶部搭设的操作平台上进行焊接作业，操作平台为钢模板构成，铺设在用钢管搭设的简易脚手架横杆上，模板没有绑扎固定，没有防护栏杆。操作平台距离地面高度约10m，系由钢结构安装工人自行搭设，搭设后没有进行检查验收。焊工在钢结构顶部作业时未系好安全带，也未系好佩戴的安全帽下颚带。
7月23日下午，施工项目部安全部门负责人向机电安装公司上报了事故，机电公司负责人接到报告后，认为已是周末，于是等到7月26日（周一）上午报告了当地人民政府安全生产监督管理部门。分析本次人身伤亡事故的直接原因。
