Abstract: Employee #1 and a crew were resurfacing a street with asphalt. They had just finished using two rollers to pack and finish the asphalt and were working on a hill with an approximately 15 percent grade when the main hydraulic pressure line blew on the 8-ton tandem Hyster roller driven by Employee #1. It was out of control and could not be stopped. A coworker operating a Hyster pneumatic rubber tired R-9 roller knew that if he did not stop the runaway roller it would go over the hill and into a house. The coworker yelled at Employee #1 and told him he was going to deliberately run into him. When he did, the back of his roller went into the air and turned over. Employee #1 fell out of his roller and onto the roadway. Employee #1 suffered minor injuries. He was not wearing a seat belt.
