For example, the welding, splicing, on-site temporary power supply, fire-fighting method, pipeline, fire-fighting coating operation and cross operation are not important in steel structure engineering, but they are all essential work.

1.Welding and replacement of steel structure engineering components.The safety distance of gas bottle B is not enough, and the distance from open fire is too close.There is no secondary no-load protection for electric welding machine. 

2.The temporary power consumption at the construction site of steel structure engineering does not meet the requirements of the specification, the leakage protection, grounding and zero connection measures of the electrical equipment are not in place, the cable used is damaged, and the joint treatment is not standardized, which is easy to cause electric shock accidents. 

3.There is no scheme for the mobile operation platform set up by fire pipeline and material mixing operation, and the erection is not standardized, which is prone to collapse accident.

4.When the steel structure engineering components are assembled in the ground, due to the nonstandard number, the frog trough is filled with plowing and pressing, and the shed structure with large quilt is not stable, so it is excited to collapse for human.
