背景资料:

A铜业公司是某大型企业的控股子公司。2013年,A铜业公司新建采用艾萨熔炼技术生产铜及硫酸的项目。项目于2013年1月开工建设,9月10日投产运行。项目主要工艺设备有艾萨熔炼炉、电炉、余热锅炉等。艾萨熔炼炉产生的高温烟气进入余热锅炉,经热交换后产生蒸汽,热交换后的烟气经除尘净化系统处理后排出。余热锅炉设计额定蒸汽压力2.5MPa、额定蒸发量35t/h、额定蒸汽温度350℃。2013年11月24日20时,当班调度员甲听到一声巨响,随机在监控系统屏幕上看到余热锅炉有大量蒸汽喷出。甲按照应急救援预案要求立即拉响警报,通知紧急停炉和现场人员撤离。21时,经人员清点,仍有5名职工下落不明,乙派2名工人进入现场查看情况,因现场蒸汽太大,2名工人被烫伤。于是紧急外调防护服,救援人员穿上防护服进入余热锅炉房,发现4名职工死亡、1人重伤。事后查明,事故发生时余热锅炉的运行压力2.3MPa,蒸汽温度310℃,从熔炼炉到余热锅炉的冷却屏波纹金属软管发生爆炸,大量高温饱和蒸汽喷出,导致现场人员伤亡。此次事故的直接经济损失为420万元。

该起事故调查组的组成单位应包括所在地市级(设区的市)人力资源和社会保障部门。
