Fatality Assessment and Control Evaluation (FACE) Project for New Jersey: Roofer Killed After Falling from a Ladder Lowered from a School Roof.

摘要

On May 13, 2005, a 26-year-old roofer was killed when he fell while climbing down an extension ladder that he had just lowered from the first story roof of a high school. The incident occured at an urban high school that had contracted with the victim's employer to renovate the school's flat roof. This was the last day of the construction project, and the work crew was completing the final tasks for the project and packing up their equipment. The victim had been assigned to clamp on a drain basket and reattach an electrical box near the edge of the roof. The victim climbed up to the roof through an interior stairwell and retrieved a 28-foot fiberglass extension ladder to the ground from the topof the 15-foot-high roof. As he started to climb down the ladder, the locking mechanism that secured the sections together failed, causing the top ladder section to suddenly slide downward. The victim fell from the ladder, striking his head on a piece of metal extending from the wall, and landed on a concrete walkway below. He died at the scene of the accident.
