This case involves a laborer who was killed by a concrete boom after a concrete pumping truck was called to a construction site. The driver pulled the truck up to the designated area and began to stabilize the pump. When the outriggers were placed, one of them fell through a patch of newly laid concrete, causing the boom to come out of place. The outrigger swung and hit a laborer in the head, killing him instantly. It was alleged that the truck and pump were not stabilized correctly before use.
