Any accident foreseen in this frame?

In the construction of provisionally closing a dam, a hydraulic excavator is lifting up those steel plates that were spread over the embankment in order to load them on a truck waiting at the back. The size of one such plate is 6,000 mm in length x 1,500 mm in width x 20 mm in thickness. Now what accident do you anticipate occurring in this frame?

This is the accident resulted!

The hydraulic excavator lifted up a steel plate and began to swing to the right, when the left undercarriage was floated and fell into the lake together with the operator. He was drowned.
