Brief description of accident:
Three people, including Guo xx, a scaffolder, led six migrant workers to the chimney lifting plate. When the lifting platform rises from 196 m to 197.5 m, two of the six inverted chains have reached the full stroke. At this time, Guo xx and Guo xx each changed a chain. When the chain hook is removed, the hanging plate will shake slightly. At this point, Yang xx, a migrant worker, stood on the higher side of the hanging tray (due to the unsynchronized pulling of six migrant workers, the tray diameter was 5.4m), only about 200~300mm away from the edge of the hanging tray. At this point, there was a gap of 400mm between the hanging plate and the brick lining, and Yang xx (male, 19 years old, contractor) fell from this gap to the ground of 0 meters, and died after being rescued.
Accident cause analysis:
(1) Inadequate protective measures for hanging boards, and the failure of constructors to wear safety belts are the important reasons for the accident.
(2) When lifting the lifting platform, there is no unified command by a special person, and the six inverted chains are not synchronized, which causes the lifting platform to tilt, resulting in a large gap on one side of the lifting platform. The direct cause of the accident was that the shaking man was unstable and fell down.
Preventive measures:
(1) Improve the safety protection facilities for hanging boards, and fasten your seat belts when working high above the ground.
(2) The lifting of the hanging plate shall be commanded by special personnel to prevent the hanging plate from tilting.
