Abstract: At approximately 1:00 p.m. on July 1, 1993, Employee #1 was cutting downward with a skill saw on a small piece of 2 inch by 4 inch by 12 inch wood for an overhead fire-block inside a residential house. He was in a hurry to cut the wood while his leadman was getting some nails from his van across the street. Employee #1 was holding the piece of wood in the air without a brace when his saw binded, bounced up, and landed on his arm, causing a 4 inch skin laceration along his inner left arm. Employee #1 was hospitalized. Employee #1, a laborer, was not authorized to use the saw. He failed to follow the company's safety rules and was reprimanded. No malfunction of the equipment or procedures was found.
