You are the operator of Dragline #1. The dragline has been losing power. After making some checks, you report damage to the trailing cable about 100 feet from the machine. An electrician and his helper come to troubleshoot. They determine that the cable needs to be repaired. It was damaged by a bulldozer working in the area. The electrician is in a hurry. He engages in unsafe work practices. You try to stop him, but he ignores you. Soon there is an accident. You must figure out how to rescue the electrician without electrocuting yourself and then provide first aid to save his life.
