Abstract: At approximately 9:00 a.m. on August 29, 1990, Employee #1, of Oakwood Lake Resort, was in a personnel platform suspended by a 20-ton P and H hydraulic mobile crane, repairing a flagpole at the resort's amphitheater. The operator raised the platform to where the block touched the boom tip. He had started to extend the 28-ft-long telescoping boom when the 0.5-in. load line stretched and then parted inside the block. The platform and Employee #1 fell approximately 25 ft to the ground. He suffered a concussion and was admitted to Memorial Hospital in Modesto, CA. The operator's view of the boom tip was obstructed by the basket.
