Abstract: At approximately 10:07 a.m. on October 2, 2012 Employee #1, a line worker with Sacramento Regional Transit District and was working at a power substation in Sacramento California. Employee #1 was using a sixteen-foot extension ladder with good rubber feet, placed on a solid level surface, to access the roof of the small building. Employee #1 had gone up and down the ladder several times before the bottom slipped out from under him as he was descending the ladder causing him to fall approximately eleven-feet to the concrete-asphalt ground below. According to Employee #1 the ladder was not tied off or secured from movement and it was not standard practice to tie off or secure ladders. Employee #1 was hospitalized as a result of the fall and sustained unspecified fractures from the event. The Employer was a local transportation authority. Employee #1 had received ladder safety training from the employer prior to the incident.
