On September 12, 2000, a 17-year-old bagger (the victim) at a retail grocery store suffered amputation of the right arm as a result of being caught in an operating meat grinder. The victim had been working in the family-owned store after school hours. On the day of the incident, a customer asked him to get some ground beef. There was none available, and no one working in the meat room. The youth decided to prepare the ground beef himself and went to the meat room to process the beef through the meat grinder. While he was operating the grinder, some of the meat became stuck in the meat grinder bowl. The youth removed the feed pan, reached with his right hand into the bowl and pushed the meat down into the grinderís worm.1 When meat fed from the bowl, the worm caught his hand and fed it into the grinderís barrel, amputating his hand and part of his lower right arm. Coworkers called 911 and emergency medical personnel responded within 5 to 10 minutes. NIOSH investigators concluded that, to help prevent similar occurrences, employers should: 1) ensure that workers are trained to recognize the hazard of accessing the internal components of operating or energized machinery; 2) prohibit workers under the age of 18 from operating power-driven meat-processing machines by implementing youth-appropriate hazardous-energy-control procedures and additionally, manufacturers of power-driven meat-processing equipment should; 3) consider design modifications or additions to provide redundant protection against the inadvertent release of hazardous energy through contact with operating machine components.
