The foreman was a scaffold contractor, and was on the roof of the building at the site. They had two trucks of scaffolding parked next to each other, side by side. There were three or four short planks bridging across the two truck beds. There were scaffold frames on the bed of the truck that were leaned up against the back of the cab. There were approximately 14 metal scaffold frames that were 3 ft wide by 6 ft tall. Each frame weighs approximately 40 lbs. Employee #1 was walking from the bed of one truck onto the other. The scaffold frames leaning at the back of the cab tipped over and fell onto the employee pushing him downward onto the bed of the truck. When he landed, he fell on top of a small pile of planks. People nearby the construction site saw Employee #1 buried by the scaffold frames came to remove them, as one contacted the Medical Emergency Services.
