问题 问答题

××年8月5日13时26分,某市某化学危险品仓库发生特大爆炸事故。爆炸引起大火,1小时后着火区发生第二次强烈爆炸,造成更大范围的火灾。直到6日凌晨5时,才扑灭这场大火。这起事故造成15人死亡,200多人受伤(其中重伤25人),直接经济损失超过2.5亿元,已经威胁到某市的安全。
经事故调查,专家组认定将干杂仓库违章改作化学危险品仓库以及仓库内化学危险品违章存放是事故的主要原因;干杂仓库4#仓内混存的氧化剂和还原剂接触是事故的直接原因。“8.5”特大爆炸火灾事故是一起严重的责任事故。
事故的间接原因
(1)某市城市规划忽视安全要求。市政府某些工作人员安全意识薄弱,对该仓库区的总体布置未按国家规定进行审查,造成易燃、易爆、剧毒化学危险品仓库、牲畜和食品仓库以及液化石油气储罐等设施集中设置,并且其与居民区和交通道路之间均不符合安全距离的规定要求。
(2)不按国家有关安全规定对该危险物品储运公司的申办报告进行严格审查,就批准成立某危险物品储运公司,属失察失职。
(3)作为民用爆炸物品发放许可证的政府主管部门,某市公安局执法不严,监督不力。未按规定严格审查,便向该公司颁发许可证,使其在不具备国家规定安全条件情况下,经营民用爆炸物品合法化。
(4)该危险物品储运公司是中国对外贸易开发集团下属的储运公司与市公安局派出的爆炸危险物品服务公司联合投资建立的,对消防及化学危险品负有监督职能的市公安局未能严格执行双重性监督职能,为其下属单位经营开方便之门。
(5)该公司凭借与公安局的特殊关系,长期违反化学危险品的安全管理规定,冒险蛮干,违章混存化学危险品,埋下祸根。
此外,该公司为获得经营化学危险品的许可,还弄虚作假,欺骗上级机关。
根据以上内容回答下列问题

答案

参考答案:(1)广义上说,可能导致重大事故发生的设备设施和场所都可能称为重大危险源。《安全生产法》第96条规定:重大危险源,是指长期地或者临时地生产、搬运、使用或者储存危险物品,且危险物品的数量等于或者超过临界量的单元(包括场所和设施)。
(2)参照《企业职工伤亡事故分类标准》(GB/6441—1986),该仓库存在的危险危害因素有:火灾、化学性爆炸、车辆伤害、起重伤害、中毒和窒息。
控制危险、危害因素的对策措施主要有:
①实行机械化、自动化;
②设置安全装置;
③机械设备、装置及其主要部件必须具有必要的机械强度和安全系数;
④保证电气安全可靠;
⑤按规定维护保养和检修机器设备;
⑥保持工作场所合理布局、整洁;
⑦配备符合要求的个人防护用品。
