  拆架前,全面检查待拆脚手架,根据检查结果,拟订出作业计划,报请批准,进行技术交底后才准工作。架体拆除前,必须察看施工现场环境,包括架空线路、外脚手架、地面的设施等各类障碍物、地锚、缆风绳、连墙杆及被拆架体各吊点、附件、电气装置情况,凡能提前拆除的尽量拆除掉。拆架时应划分作业区,周围设绳绑围栏式竖立警戒标志,地面应设专人指挥,禁止非作业人员进人。拆除时要统一指挥,上下呼应,动作协调,当解开与另一人有关的结扣时,应先通知对方,以防坠落。在拆架时,不得中途换人,如必须给人时,应将拆除情况交代清楚后方可离开。每天拆架下班时,不应留下隐患部位。拆架时严禁碰撞脚手架附近电源线,以防触电事故。所有杆件和扣件在拆除时应分离,不准在杆件上附着扣件或两杆连着送到地面。所有的脚手板,应自外向里竖立搬运,以防脚手板和垃圾物从高处坠落伤人。拆下的零配件要装人容器内,用吊篮吊下;拆下的钢管要绑扎牢固,双点起吊,严禁从高空抛掷。
