Poling based to consolidate foundation is not solid formation collapse poling flat Rachel not standard, set up strong, not according to standard rules set bracing scaffolding collapse should be according to the engineering construction needs and carrying weight, according to the rules of the erection. Special open separate method and safety measures of field use scaffolding tight safety net is not in conformity with the product standards, without inspection certificates, falling objects, hit the scene using dense mesh net due production license and product certificate and check regularly. Storm, typhoon and flood season before and after, not to the construction site of the tower crane, lift, derrick, scaffolding and spin the power facilities such as line inspection, repair, reinforcement mechanical injury, electric shock, other damage in accordance with the provisions in the storm, typhoon, flood season before and after, to the construction site of the tower crane, derrick, scaffolding and construction of the power supply facilities for inspection, maintenance, reinforcement, to ensure the safe use of scaffolding plank under lead wire bundle, the four corners and unused, and scaffolding lateral not set federated eye network, falling scaffolding full shop, four corners with lead wire binding, scaffold outside with federated eye network, close intervals of 3 m high with a AnQuanPing network construction scaffolding materials do not conform to the standard before the collapse of scaffolding, should choose the material of good material and specifications, the fir pole do bearing scaffold is strictly prohibited. A scaffolder a demolition operations erection of scaffolding should be collapsed by trained and set-up, and who, for a operation certificate, a professional scaffolding can only take the disassembly and maintenance, anyone not allowed to dismantle and destroy any part of the scaffold by demolition workers did not admire set-up personnel safety protection appliance falls and other injuries required dress neatly, complete security protection products to wear
