They are one of the "three major injuries" (falling from heights, collapse, and object impact) accidents in the construction industry. Falling accidents from heights are caused by working at heights, so they can be simply classified according to the classification form of working at heights. According to the "Classification of Work at Heights", any work performed at heights where there is a possibility of falling above 2m (inclusive) from the reference plane is called work at heights.

In 2022, a falling accident occurred from a height in the second-floor workshop of a company in Shenzhen during the renovation process. A construction worker fell from the ceiling and landed on his head. He died after being sent to the hospital but failed to rescue him. Our appraisers went to the workshop on the second floor of the factory building where the incident occurred to conduct an inspection, and conducted an on-site inspection of the ceiling and electrical environment at the scene.

Our company was entrusted by the client to conduct a technical appraisal of the "fall from height" accident and find the direct cause of the accident.

identification analysis results:

The identification expert group discussed and comprehensively analyzed the relevant information, on-site inspection and test data of this "fall from height" accident, and gave the following identification opinions.

The personnel involved had a weak sense of safety. They illegally climbed onto a ceiling that was not accessible to people, failed to take 57% protective measures to prevent falls from heights, and did not wear a safety helmet correctly. They accidentally collapsed the observation hole cover and fell to the ground, causing the accident.
