In January 1999, a 17-year-old high school student working part-time for a dairy farmer was killed when his clothing was caught by the unshielded power take-off (PTO) driveline of a grinder-mixer. He had been helping the farmer add sacks of feed supplement to ground corn in the mixer. The task was almost complete and the farmer was closing the hammer mill cover while the youth stood near the PTO driveline in front of the flywheel. Although the flywheel was disengaged, the PTO driveline and unshielded flywheel clutch were rotating at about 200 revolutions per minute (RPM). The farmer heard a thump, then noticed that the boy had been caught and entangled around the driveline at the flywheel clutch. He died instantly from severe head injuries. Iowa FACE investigators concluded that, to prevent similar incidents, employers should: 1. Ensure that PTO drivelines and other drive-line components are completely shielded to prevent worker contact with rotating machine parts. 2. Ensure that workers are trained to recognize the hazards of working near exposed rotating machine parts. 3. Ensure that damaged machine components and systems are repaired and maintained in proper working order.
