Abstract: At 3:45 p.m. on December 23, 1991, a three-man crew of Capital Neon was installing a neon sign at a cafe using a sign boom truck to place the letters on the side of the building. Two members of the crew made an adjustment on a slipping V-belt and pulley, which drove the gears and raised the boom. Upon tightening the belt and securing the hold-down bolts, Employee #1 reached in and pulled the V-belt to check the tension. Unaware, a coworker turned on the motor and Employee #1's finger was caught in the belt and pulley, which removed the flesh from the last joint of his left index finger. First aid was administered before Employee #1 was transported by ambulance to UC Davis Medical Center.
