Abstract: Employee #1, a gearbox rebuilder for Fisher's Gear & Machine Co., Inc., Los Angeles, CA, was working on a gearbox for a wind generator. The gearbox was detached from the wind generator and sitting open on a bench in the employer's shop. The bull gear on the gearbox was 30 inches in diameter and, when rotated by hand, would keep its momentum and continue to turn. The employee had applied transfer blueing and was rotating the bull gear by hand to look for high spots on the gear teeth when his right hand was caught between the bull gear and the pinion gear, amputating his right middle fingertip and crushing his right ring finger.
