鞍钢炼铁厂1969～1983年共发生 CO 急性中毒事故214人次(通常所说的煤气中毒,就是 CO 中毒)。其中事故资料比较完整的有192人次,中毒情况见下表。一、原因分析1.换渣口和做泥套时引起中毒历年测定结果表明,渣口 CO 平均浓度为171.5mg/m~3,波动范围为6250～0mg/m~3,如果在最高浓度下工作,几分钟就会引起中毒;由于出渣次数频繁,工人做换渣口泥套的时间较多,因此,中毒机会也较多,占各种作业的第一位。加上新工人缺乏
Angang Iron & Steel Co., Ltd. from 1969 to 1983, a total of 214 people were acute CO poisoning accidents (commonly referred to as gas poisoning, CO poisoning). Incident information more complete 192 people, poisoning situation in the table below. First, analysis of the reasons 1. Slag mouth and mud caused by poisoning over the years measured results show that the average concentration of slag mouth CO is 171.5mg / m ~ 3, the fluctuation range of 6250 ~ 0mg / m ~ 3, if at the highest concentration Work, a few minutes will cause poisoning; as a result of frequent slagging, workers do slag shackles for more time, therefore, more poisoning opportunities, accounting for all kinds of homework first. Coupled with the lack of new workers
