Power, lighting line shunt settings; and a reasonable selection of rated residual operating current leakage protection, with grading, strictly enforce the "three distribution secondary protection", "a machine a gate a box of a drain" system. 4) provided at the workplace and passage lighting. Site lighting all use of soft rubber sheathed cable and have GFCI protection, illumination lead not just to drag or tied around the scaffolding and other facilities stand. 5) All electrical equipment insulation do good; all electrical equipment leakage protection device is installed and grounded. Unauthorized persons not to use electrical equipment, all electrical equipment by the person responsible for inspection and maintenance. Create a file for each electrical equipment. 6) tool flexible cable plugs do not arbitrarily dismantled, replaced. Flexible cables do not any longer. Room 7) Electrical warning signs and have someone manage. Construction site does not use an extension cord. 8) Electric machinery and hand tools are located two leakage protection device. Welding, cutting machines and other equipment will be installed randomized controlled AC contactor or steel switch, and then protect the zero line, without using inverted switch. Site security staff to deal with scaffolding, mast, tower cranes and other construction equipment collapse accident cause analysis, development of appropriate corrective measures for handling reports of casualties fill out report forms, accident investigation and reporting corporation emergency rescue leading group. Sent to hospital immediately after the (11) should be subject to fracture with a splint and other simple fixed promptly. 4, in the excavation process, such as the case of the following circumstances, the appropriate measures and methods to be taken: 1) When the supporting structure surface cracks must be promptly clay or cement block. 2) When the side wall of the supporting structure when soil water leakage, plugging water should take timely and effective measures. 3) excavation deformation exceeds the allowable value or when premonitory should immediately adopt the following measures:
