Because this building is no longer inhabited after a family fire, it should be managed by the state, and the camera is installed on the roof.

The direct cause of the accident:

During the construction of the energy-saving comprehensive renovation project of No.728 apartment building in Jiaozhou Road, the construction workers illegally carried out electric welding outside the north window of the elevator foreroom on the 10 floor, and the molten metal splashed by electric welding ignited the fragments and chips of polyurethane insulation materials piled up on the scaffold protection platform on the 9 floor below, which caused a fire.

But if there is such a thing, it can't be so calm, so the photos on the Internet are probably because everyone is following the trend.

Indirect causes of fire in JIAOZHOU Road, Shanghai;

A, the construction unit, bidding enterprises, bidding agencies collude with each other, false bidding, subcontracting, illegal subcontracting.

Second, the project construction organization and management is chaotic.

Third, it is the dereliction of duty of design enterprises and supervision institutions. Fourth, the municipal and district construction departments lack supervision and management of the project. Fifth, the public security fire control institutions in Jing 'an District failed to supervise and inspect the project. Sixthly, the Jing 'an District Government has poor leadership on the organization and implementation of the project.
