Abstract: At approximately 11:15 a.m. on November 12, 2012, Employee #1 of Young's Roofing, Inc. fell from an extension ladder when it collapsed while he was installing a piece of flashing about 14 feet up on the building wall. Employee #2 was working nearby and both Employee #1 and Employee #2 said the ladder was resting on the building at a point about 15 feet above the sidewalk. According to both workers, the bottom rails of the ladder were four to five feet away from the wall. Employee #1 said he was unable to find a tie-off point for his ladder. Employee #2 said he was setting upon a second ladder on the same wall. Employee #1 said he was transferring pressure of his right arm and torso onto the ladder while he was using a cordless power-driver to install screws for the flashing into the wall. Employee #1 felt that this is what dislodged the ladder from the bottom outward, away from the wall. Employee #1 was taken to Stanford Hospital for treatment of injuries including two broken wrists and orbital skull fracture. He was released on November 15, 2012.
