Any accident foreseen in this frame?
An operator is trying to load a mini hydraulic shovel on a truck. His unique method of loading in such a case is; first of all he does not use ramps, but instead hang the tip of the undercarriage on the edge of a truck body with the help of the boom and arm, NEXT swing the upper structure to face the rear, then lift up the rear part of the machine again with the help of the boom and arm, and lastly let the machine travel forward to the center of the truck body.
Now what accident do you anticipate from this picture?

This is the accident resulted!
When the operator swung the upper structure to the right, the machine was thrown off the balance and rolled over to the left side. He was thrown out of the operator's seat then and killed under the fallen machine.

Tips for forestalling similar accidents
1. For transportation of construction vehicles, prepare for a special truck as well as use ramps for loading and unloading for the purpose of assuring safety.
2. Appoint a conductor for the work of loading and unloading of construction vehicle from a truck or trailer. All the parties concerned will follow his/her instructions. The conductor will decide the work procedures and method, and then have everyone understood them.
3. Implement safety education and training, in course of which various hazards resulting from the work and their causes are clearly indicated, so that the workers' safety awareness may be enhanced.
