2011年安全生产事故案例分析习题(18)

  某年2月,某石化厂焦化车间,在焊接一处管线连接处时,没有对距用火地点只有1.2M 的污水井进行有效遮盖;动火前车间既没有到现场检查落实用火安全措施,动火时又没有看火人在场,致使电焊火星落到污水井中,引燃井内的瓦斯气,发生爆燃,并串入污水明沟,引发大火。直接经济损失高达21万元。

  一、单项选择题

  1.以下选项中,不属于可燃液体的是_

  A.四氯化碳  B.三甲苯  C.环己烷  D.乙二醇

  2.在焊割动火作业中,必须采取安全措施。下列选项中,叙述错误的是_

  A.动火人员必须持证上岗  B.进行动火作业前必须报告班组长

  C.动火前必须清除动火地点周围可燃物  D.动火后必须彻底熄灭余火

  三、简答题

  5.防止发生火灾、爆炸事故的基本原则是什么?

  参考答案

  1. A  2. B  3. ABD  4. ABD

  5.防止发生火灾、爆炸事故的基本原则是:(1)防止与限制可燃气体与空气形成燃烧、爆炸性混合物(可燃气体在空气中浓度处于爆炸极限范围内);(2)消除各类点火源;(3)预先采取措施,使得一旦发生燃烧爆炸危险,能够阻止和限制火灾遇爆炸后蔓延及扩展。
