Ramon A. Saldana, contractor consultant, age 67, was fatally injured on September 1, 2008, when he fell through an opening in an elevated travelway 28 feet to the ground. The opening was created by removing sections of grating to lower tools and equipment to the ground below. The accident occurred because management policies and controls were inadequate and failed to ensure that the opening in the travelway was provided with railings, barriers, or covers when not in use. GENERAL INFORMATION
Freeport-McMoRan Morenci Inc., a surface copper mine, owned and operated by Freeport-McMoRan Morenci Inc. was located in Morenci, Greenlee County, Arizona. The principal operating official was Hunter White, general manager. The mine employed 3,500 employees working two,11-hour shifts, 7 days a week. Copper ore was drilled, blasted, and transported by trucks and conveyors to the mill for processing. The finished products were sold to commercial industries. Geotemps Inc., an employment staffing company, was located in Reno, Nevada. The principal operating official was Carla Anderson, staffing manager. Geotemps Inc. was contracted by Freeport-McMoRan Morenci Inc. to provide one employee, Ramon A. Saldana, who normally worked one,8-hour shift, 5 days a week. Saldana provided consultant services to mine personnel regarding various mine projects. Freeport-McMoRan Morenci Inc. supervised and trained Saldana and provided personal protective equipment to him. The last regular inspection at this operation was completed on August 24, 2008. DESCRIPTION OF THE ACCIDENT
On September 1, 2008, Ramon A. Saldana (victim) started work at 6:00 a.m., his normal starting time. He met with Juan Herrera, miner; Ralph Valenzuela, miner; and Ronald Jurado, supervisor. They held a safety meeting to discuss an ongoing project, referred to as the BC belt conveyor repair project that began on August 25, 2008. The BC belt conveyor was located in the #6 bedding area building at the mill. After the meeting, Herrera and Valenzuela went to the BC belt conveyor to complete the project. Valenzuela donned his fall protection, removed two sections of grating, and lowered tools and equipment to Herrera on the ground below. After lowering the tools and equipment, Valenzuela went to the head pulley section of the BC belt conveyor and discussed the replacement of guards with Jurado. The floor grating was not replaced at this time. Herrera remained on the ground to put away the tools and equipment. During the morning, Saldana was in the BC belt conveyor area several times to check on the progress of the job. He was last seen leaving the area about 9:45 a.m. Saldana apparently returned to the area near the opening. At 10:02 a.m., Herrera saw a glimpse of something hit the ground in front of him. He looked closer, saw Saldana lying on the ground, and yelled for help. Jurado and Valenzuela went to the accident scene and then called the company dispatcher for help. Greenlee County emergency medical services arrived and the victim was pronounced dead by the emergency medical physician at 11:49 a.m. Death was attributed to blunt force trauma.
