Abstract: On April 18, 2005, Employee #1 and two coworkers were demolishing a residential chimney. They had erected a scaffold, but it did not let them safely reach the top of the chimney from the chimney's front. The two coworkers proceeded with other tasks inside the house, leaving Employee #1 to work alone. Attempting to gain access from the rear of the house, he set up an extension ladder on the roof of a porch. That roof had a pitch of 4-in-12. When he climbed the ladder, it slipped. He fell to the ground, sustaining injuries to his right hand, left wrist, and head, including a concussion. He was hospitalized. His employer is a new firm, and the firm's owner had been meeting with a safety consultant to develop an "IIPP" - an Illness and Injury Prevention Program, required by California law.
