建立安全生產管(guan)理制度

1、危(wei)險(xian)性(xing)較大的分部分項(xiang)工程應建(jian)立安全生產責任制，嚴格執行有(you)關規定。

施工(gong)企(qi)業各級領導，在管(guan)理生產的同時，必須負(fu)責(ze)管(guan)理安(an)全(quan)工(gong)作，逐級建立安(an)全(quan)責(ze)任制，使落實安(an)全(quan)生產的各項(xiang)規(gui)章制度(du)成為全(quan)體職工(gong)的自覺行動(dong)。

2、建立安全技(ji)術措(cuo)施計劃，包括改善勞(lao)動條件，防止傷亡事(shi)故，預防職業病和職業為目的各項技(ji)術組織措(cuo)施，創造(zao)一個良好的安全生(sheng)產環境(jing)。

3、建立嚴格的勞(lao)力管(guan)(guan)理(li)制度(du)。嚴格執行公(gong)司勞(lao)力管(guan)(guan)理(li)制度(du)，勞(lao)力由(you)勞(lao)工(gong)科統一安排。新(xin)入場的工(gong)人接受入場安全(quan)教育后方可上崗操作。特(te)種(zhong)作業人員全(quan)部(bu)持證上崗。
