危险预知活动是由日本住友金属矿山公司和歌山冶炼厂于1973年首先提出来的,实践证明效果很好,因此很快在日本的各企业普及。日本东予冶炼厂在开展危险预知活动后,伤亡事故大幅度减少,直至事故几乎为零。 Dangerous activity was first proposed by Japan’s Sumitomo metal mining company Wakayama Smelter in 1973, proved to be very effective and therefore quickly spread in various Japanese enterprises. After carrying out the danger prediction activities, the East Japan Smelting Works substantially reduced the number of fatalities and injuries until the accident was almost zero.
