Abstract: On November 11, 2003, Employee #1 was operating a trim saw. A piece of fir material, measuring approximately 1 inch by 2 inches by 6 feet, was launched from the trim saw towards Employee #1. The wood struck Employee #1's cab glass and penetrated it. The cab glass consisted of lexan safety glass and was 0.25-inches thick. As the piece of wood came through the safety glass, a section of the wood splintered off and struck the operator on the left side of his face. Employee #1 was hospitalized and treated for a fractured jaw and soft tissue damage along the left side of his face past his left ear.
