防范硫化氢中毒的安全技术措施
 (一)气体检测

  1、用人单位要摸清自身界内存有硫化氢等有害气体的危险源分布情况(如塔、沟、池、釜、罐、下水道等),定期进行气体监测和分析;

  2、作业前,应对作业环境进行监测,判明是否存在硫化氢等有毒有害气体和空气中氧气的含量情况。允许接触值参考常见有毒有害气体允许浓度和爆炸范围和《工作场所有害因素职业接触限值》(工作场所空气中有毒物质容许浓度);

  3、作业中,应保持必要的测定次数或连续监测;

  4、气体检测仪必须符合国家标准并定期检测;

  5、气体检测应由取得监测资质的单位和人员进行。

  (二)通风、降水

  1、作业前,必须先行通风。采取自然通风或人工强排通风的手段,污水管道内按照平均风速0.8m/s计算通风机的风量,作业场所有毒有害、易燃易爆气体允许浓度达到国家标准后,方可进行作业;

  2、对于硫化氢浓度变化大的作业,必须同时进行通风;

  3、固定封闭式的沉淀池、纸浆池等设施,必须装设固定的机械通风系统,池的进入口面积不应小于1. 5平方米,并在开口上方加装安全防护网,凡不宜装设固定式通风系统的,必须配备移动或便携式的通风设施;

  4、对于进入管道内的作业,作业前必须提前降水,避免潜水作业,作业时要联系好上、下游水泵停车、开车时间,防止溺水事故发生。
