At about 10:11 a.m. on June 18, 2013, Employee #1 was working for Roofline Inc., which was dba Roofline Supply & Delivery in San Mateo, CA. Employee #1 and a coworker had been directed by their employer to deliver roofing materials for construction at a residential roof repair project. The project was taking place at a two-story residential townhouse on a hillside lot. Employee #1 positioned a truck outfitted with a conveyor for lifting 4-inch by 4-foot by 8-foot (100-millimeter by 1.22-meter by 2.44-meter) sheets of composite sheathing and insulation onto the roof. Employee #1 climbed a ladder onto a scaffold platform from which he could access the roofs of the condominiums. Employee #1 was receiving the materials and stacking them on racks placed on the roof. The roof had a pitch of approximately 4:12. Employee #1 said he had attached an anchor to the roof for a safety line and was wearing a safety harness during his first period of work on the roof. His coworker affirmed that Employee #1 was using the fall protection prior to taking a break. Following the break, the coworker was returning to the truck when he learned that Employee #1 had fallen from the roof. The coworker found Employee #1 unconscious and being assisted by a worker for the roofing installer on a stair landing. Employee #1 stated that he had prepared to go on break by removing his harness and leaving it near the ridge of the roof where his safety line was anchored. When he returned to the roof to resume work, Employee #1 said he had decided to walk down the sloping roof and then along the eaves at the lower edge of the roof. He was going to do this because some of the roof area was taken by stacks of 4-foot by 8-foot (1.22-meter by 2.44-meter) sheets of composite sheathing and insulation. Employee #1 stated that as he walked along the roof edge, he slipped on some cut sections from the composite construction sheets and then lost his balance. According to the fire department report and a worker with the roof installers, Employee #1 first struck and broke a wooden deck railing at the second-level entrance to the residence and then fell onto a landing of the concrete stairs below. The fall distance to the deck below the eave measured about 16.5 feet (5.0 meters), and the fall distance to the landing on the stairs where Employee #1 came to rest measured about 6.5 feet (2.0 meters), for a total fall distance of about 23 feet (7.0 meters). Employee #1 was taken to Stanford Hospital, where he was admitted and treated for injuries to his head and left leg and calf. The narrative did not state the nature of his injuries. He was released on June 20, 2013. No witnesses to the Employee #1's fall were identified. Employee #1 had delivered roofing materials for about 10 years for the prior owner of the business operation. Ownership of the business had changed, and the new corporation had taken over about 10 days before this incident. Employee #1 said that the materials he slipped on were not an excessive amount of debris. The employer provided evidence that the personal fall protection systems they supplied included safety lines, full harness and lanyard with shock relief, and rope-grab handle grip. Employee #1 and his coworker worked as a team, and there was no foreman or supervisor for the delivery crews. These citations were issued: General -T8 CCR 3210(a): Failure to ensure that an employee was protected from falls at elevated location. * General -T8 CCR 3395(f)(3): Failure to have all required written procedures for heat illness prevention. The incident was reported in a timely fashion to DOSH by the employer and by Cal/Fire.
