What are the "five major injuries"?

The "five major injuries" are: falling from a height, collapse, object strike, mechanical injury and electric shock. According to incomplete statistics, the above five major injuries account for more than 95% of all accidents.

1, falling from a height

People fall from a height of more than two meters near the edge and the hole (including stairs, elevators, reserved holes and passages; Around ditches, pits, troughs and deep foundations; One side of the stairs; Edge of platform or balcony; Around the roof) and scaffolding, hanging baskets, tower cranes, elevators, construction elevators and other high-altitude falling accidents caused casualties.

Step 2 collapse

Collapse injury refers to the safety accidents caused by the instability and collapse of buildings, structures, piles, earthwork and scaffolding. Because the strength of the bottom support cannot resist the upper load.

3. Object impact

Object strike injury refers to an accident in which the inertial force of an out-of-control object causes personal injury or death. Simply put, it is a personal casualty accident caused by falling objects.

4. Mechanical damage

Mechanical injury refers to such injuries as squeezing, collision, impact, shearing, winding, twisting, throwing, cutting, cutting off and stabbing caused by the movement of mechanical equipment (static) and the direct contact between parts, tools and machined parts and human bodies. Does not include injuries caused by vehicles and lifting machinery.

5, electric shock injury

Electric shock injury is an accident in which the human body directly contacts the power supply (leading to charged body or leakage body) and a certain current passes through the human body, causing tissue damage and dysfunction and causing casualties.

Extended data

accident cause

1, violating safety operation regulations.

2. Not using or not using the safety "three treasures" correctly.

3. Workers lack due safety knowledge and awareness.

4. On-site safety inspection is not in place, potential safety hazards are not found and rectified in time, and safety protection measures are ineffective.

5, the legal consciousness is not strong, workers have no right to know the construction safety environment before entering the construction site; 6. Have the right to refuse the construction before the potential safety hazard is eliminated.

situation

There is a 10kV overhead line passing through the east-west direction of a construction site, and the height of the high-voltage line is about 7m from the ground. When earthwork backfilling is completed, the overhead line is only 5.6 meters from the ground. During this period, the construction unit has repeatedly asked the construction unit to move as soon as possible, but it has never been resolved. The construction unit has been taking risks under the high-voltage overhead line without taking any measures.

At the time of the accident, the on-site management personnel illegally commanded 12 migrant workers, and when placing a 6-meter-long steel cage into the pile hole, the top steel bar was too close to the high-voltage line to generate an arc, which knocked 1 1 migrant workers to the ground, causing 3 deaths and 3 injuries.
