Machine operator crushed by robotic platform.

NIOSH 2000 Jan; :1-7
A 23-year-old carousel operator, at a meat packing plant, was killed when his foot tripped a light sensor causing a computer controlled robotic platform to come down from above, crushing his skull. He had been watching a maintenance technician work on a conveyor and apparently stepped on the conveyor to get a better view of what the mechanic was doing. The conveyor the mechanic was working on had been shut off but the entire system had not been locked out. Power still remained to the light sensors and the robotic platform. When the platform came down it pinned the victim between the platform and the conveyor. When they lifted the platform off the victim, the victim fell approximately 15 feet to the concrete floor below. Death was most likely caused by the blow to the head from the robotic platform, not the fall. The victim was pronounced dead at the scene. The Nebraska Department of Labor Investigator concluded that to prevent future similar occurrences employers should: 1. ensure all equipment is properly locked out/tagged out prior to performing maintenance on it. 2. consider implementing a spot inspection program to ensure all employees are complying with safety requirements. 3. develop procedures to ensure individuals not involved in maintenance activities are not in the immediate area of the maintenance being performed. 4. consider installing a protective grate around access areas to the robotic platform.
