城市排水管道维护井下作业硫化氢气体中毒事故安全防护【摘要】近年来,我区有毒有害危险作业场所中毒事故呈多发态势,特别是硫化氢气体中毒事故的接连发生,严重危害了从业人员的健康和生命安全,给我们的安全管理工作敲响了警钟。
因此我们安全生产管理人员必须认真总结经验,深刻吸取教训,杜绝类似事故的发生。
据统计2006年以来,我区在地下管线、密闭和通风不良等有限空间作业过程中,因操作不规范已发生了19起中毒窒息伤亡事故,死亡28人。
尤其是2011年8月份以来,我区在进行排水管道维护井下作业时连续发生3起硫化氢气体中毒伤亡事故,后果极其严重,教训极为惨痛,严重危害了从业人员的健康和生命安全,给我们的安全管理工作敲响了警钟。
分析资料显示,硫化氢气体中毒事故发生频率和死亡人数呈明显的上升趋势,作为安全生产管理人员应该更能深刻体会“安全责任重于泰山”这句话的份量,因此我们必须认真总结经验,深刻吸取教训,杜绝类似事故的发生。
本文结合实际案例,着重分析城市市政排水管道维护井下作业硫化氢气体中毒事故发生的原因及预防措施。

So we personnel for the administration of production safety must be carefully summarize experience and profound draw lessons, and prevent similar accidents.According to the statistics since 2006, in my district underground pipeline, airtight and poor ventilation and limited space in the process of work, because of improper operation has been 19 up poisoning suffocation casualty accidents, 28 people died. Especially since August 2011, the drainage pipeline maintenance of our working underground continuous happen when the hydrogen sulfide gas poisoning 3 casualty accidents, the consequence is extremely serious, very painful lesson, serious harm from personnel of the health and safety of life, to our safety management work was a wake-up call. Analysis data shows, hydrogen sulfide gas poisoning accidents frequency and the death toll is obviously rising trend, as personnel for the administration of production safety should be more to deeply understand “security responsibili ty than mount tai” this sentence of weight, so we must carefully summarize experience and profound draw lessons, and prevent similar accidents. This paper combining with actual cases, this paper mainly analyzes the city drainage pipeline maintenance underground work hydrogen sulfide gas poisoning the cause of the accident and preventive measures.【key words 】urban drainage pipeline maintenance, hydrogen sulfide gas, poisoning accidents, cause analysis and prevention measures一、硫化氢等有毒有害气体产生原因:城市排水管道井下作业是市政行业排水管道养护、维修和排水工程施工、排水泵站运行以及防汛抢险中经常遇到的生产和施工项目,其主要工作内容是下井检查、维修;管道疏通、清淤;管道内砌堵、拆堵、接管;城市防洪沟盖板沟清淤;排水泵站集水池清淤;各种闸门井维护检修等。
