主次图分析法及其重点控制主次图分析法是一种分析寻找事物主要矛盾的科学方法,运用此方法,对鞍钢冶金工厂35年间发生的工亡事故进行分析,得出车辆伤害、物体打击、起重伤害、高处坠落、烧烫、触电、机械伤害等七类事故占总数的87.7%,分别处于 AB 区内,若使这七大伤害得到有效的控制,则工亡事故将减少90%左右。所以,从1984年开始,鞍钢把安全管理的重点放到防止七大伤害事故上。例如,为防止车辆伤害,加强了厂内铁路道口的管理,投资20多万元,增设了六处铁路道
The primary and secondary chart analysis and its emphasis control The primary and secondary chart analysis is a scientific method to find out the main contradictions of the matter. By using this method, it analyzes the accidents that occurred during the 35 years in Ansteel Metallurgical Factory, The seven types of accidents, such as striking, lifting injuries, falling from height, scald, electric shock and mechanical injury, account for 87.7% of the total, respectively, within the AB area. If the seven major injuries are effectively controlled, the accidents will reduce About 90%. Therefore, since 1984, Anshan Iron and Steel put the focus of safety management to prevent the top seven injuries. For example, in order to prevent vehicle injuries and strengthen the management of the factory railroad crossing, it invested over 200,000 yuan and added six railroad tracks
